Description

Technical Field

[0001] The invention relates to the technical field of ore processing, in particular to a ball mill for processing molybdenum ore. Background Art

[0002] Molybdenum is an element with a relatively small distribution in nature, with an average content of about 0.001% in the earth's crust. Molybdenum is increasingly valued for its special properties such as high melting point and good high-temperature strength, and has become an indispensable metal in industrial sectors such as steel, petroleum, and chemicals. Molybdenum ore is a mineral aggregate containing the element molybdenum, and the main minerals include molybdenite, copper-molybdenum ore, tungsten-molybdenum ore, etc.

[0003] In the process of molybdenum ore processing, in order to obtain molybdenum ore of the required particle size, the crushed molybdenum ore needs to be further refined; in the process of molybdenum ore refinement, a ball mill is needed. In the related technology, for example, Chinese patent CN117548193B discloses a ball mill for quartz sand, which is used for quartz sand. The ball mill is provided with a liner group in a grinding barrel, and the liner group includes a first liner and a second liner, wherein the first liner is bolted to the inner wall of the grinding barrel, and the second liner is movably connected to the first liner, and any two adjacent liner groups along the ring in the grinding barrel are inserted through an insertion port provided below the second liner. The second lining plates are elastically connected, and an elastic limiting column is arranged at the bottom of the second lining plate. By arranging a protrusion with multiple arc-shaped contact surfaces, it is responsible for bearing the impact of the falling grinding body while driving the grinding body and the grinding material to rise. The arc-shaped structure of the protrusion decomposes a part of the impact force in the direction of the insertion port and buffers it through the displacement between the second lining plates. The remaining longitudinal force is converted into the pressure of the second lining plate on the first lining plate and the pressure between adjacent second lining plates through the elastic limiting column. At the same time, the pressure between adjacent second lining plates is further decomposed into lateral extrusion displacement through the arc-shaped structure.

[0004] Although the above-mentioned ball mill for quartz sand can improve the service life of the liner to a certain extent, it is found during use that when installing the first liner, its circumferential layout of the grinding barrels and its own processing errors easily lead to installation difficulties; and in the process of crushing the molybdenum ore, the particle size of the molybdenum ore will gradually become smaller and eventually appear in powder form. These powdered molybdenum ores will gradually become blocked between the liners, thereby affecting the shock absorbing performance of the elastic component. Summary of the invention

[0010] Furthermore, the first elastic shock-absorbing plate and the second elastic shock-absorbing plate are both capable of moving along the circumference of the grinding cylinder, and the first elastic shock-absorbing plate and the second elastic shock-absorbing plate on the same liner have a tendency to move in opposite directions, so as to achieve misalignment and increase the curvature of the first elastic shock-absorbing plate and reduce the V-shaped angle of the second elastic shock-absorbing plate; the ball mill for processing molybdenum ore also includes an adjusting mechanism, which is configured to adjust the distance that the first elastic shock-absorbing plate and the second elastic shock-absorbing plate on the same liner move in opposite directions according to the amount of molybdenum ore accumulated between two adjacent liner plates, so that the greater the amount of molybdenum ore accumulated between two adjacent liner plates, the greater the distance that the first elastic shock-absorbing plate and the second elastic shock-absorbing plate on the same liner move in opposite directions.

[0011] Furthermore, the adjustment mechanism also includes a transmission assembly, a second transmission rod and a third transmission rod, the number of which is equal to the number of the lining plates, and the transmission assembly and the first transmission rod are arranged in a one-to-one correspondence; the second transmission rod and the third transmission rod are arranged in parallel with the first transmission rod and can rotate on their own; one second transmission rod and one third transmission rod form a group, and the second transmission rod and the third transmission rod of the same group are respectively arranged on both sides of the same first transmission rod, and under the action of the transmission assembly, the second transmission rod and the third transmission rod of the same group can rotate in opposite directions; each of the second transmission rods is sleeved with a plurality of A first cam is provided, and a first cam on the same second transmission rod and a first elastic shock-absorbing plate on the same lining plate are arranged correspondingly, and when the second transmission rod rotates, the first cam can rotate synchronously in one direction to push the first elastic shock-absorbing plate to increase the curvature of the first elastic shock-absorbing plate; a plurality of second cams are sleeved at intervals on each of the third transmission rods, and a second cam on the same third transmission rod and a second elastic shock-absorbing plate on the same lining plate are arranged correspondingly, and when the third transmission rod rotates, the second cam can rotate synchronously in one direction to push the second elastic shock-absorbing plate to reduce the V-shaped angle of the second elastic shock-absorbing plate.

[0016] The beneficial effects of the present invention are: The present invention provides a ball mill for processing molybdenum ore. When installing the liner, the layout of the multiple liner equally spaced along the circumferential direction allows the liner to have a larger processing error, thereby facilitating the improvement of the installation speed. When grinding the molybdenum ore, the molybdenum ore is firstly put into the grinding drum. At this time, the layout of the multiple liner equally spaced along the circumferential direction allows the molybdenum ore to be relatively concentratedly distributed, and then in the subsequent grinding process, the thrown grinding balls can crush the concentrated molybdenum ore, which is conducive to improving the crushing efficiency. Then the grinding drum is driven to rotate. During the rotation of the grinding drum, the centrifugal force generated by the rotation of the grinding drum brings the grinding balls to a certain height and then falls, so that the grinding balls can produce a heavy impact and grinding effect on the molybdenum ore. The kinetic energy of the molybdenum ore and the grinding balls is then consumed by the shock absorbing part, which reduces the wear of the liner and prolongs the service life of the liner. At the same time, the cleaning mechanism can regularly clean the molybdenum ore between two adjacent liner plates, thereby preventing the molybdenum ore from being continuously stuck between the two adjacent liner plates, which is conducive to improving the overall grinding effect of the molybdenum ore.

[0017] Furthermore, by setting the first elastic shock-absorbing plate to be an arc-shaped structure with the convex surface facing the axis of the grinding cylinder; the second elastic shock-absorbing plate to be a V-shaped structure with the small end facing the axis of the grinding cylinder, when in use, the dropped grinding balls are more easily distributed between the two second elastic shock-absorbing plates corresponding to the two adjacent liner plates, so that the grinding balls can be distributed more evenly in the axial direction, which is beneficial to improve the uniformity of the grinding balls in crushing molybdenum ore.

[0018] Furthermore, by setting an adjustment mechanism, when the amount of molybdenum ore accumulated between two adjacent lining plates is greater, the distance that the first elastic shock-absorbing plate and the second elastic shock-absorbing plate on the same lining plate are adjusted to move in opposite directions is longer, thereby making the first elastic shock-absorbing plate and the second elastic shock-absorbing plate convex to a greater extent. On the one hand, it can improve the pushing ability of the first elastic shock-absorbing plate and the second elastic shock-absorbing plate for molybdenum ore, and reduce the problem of deterioration in the grinding effect of molybdenum ore caused by the particle size of the molybdenum ore becoming smaller and difficult to lift in the later stage. On the other hand, it can increase the deformable amount of the first elastic shock-absorbing plate and the second elastic shock-absorbing plate, which is beneficial to improve the shock-absorbing capacity of the first elastic shock-absorbing plate and the second elastic shock-absorbing plate; and it can make the misalignment between the first elastic shock-absorbing plate and the second elastic shock-absorbing plate larger, which is beneficial to increase the shock-absorbing interval composed of the first elastic shock-absorbing plate and the second elastic shock-absorbing plate.

[0024] like Figures 1 to 10 As shown, a ball mill for processing molybdenum ore provided by an embodiment of the present invention is used for ball grinding molybdenum ore, and is configured to include a horizontally placed grinding cylinder 2, a plurality of grinding balls, a plurality of lining plates 3 and a cleaning mechanism 4, wherein the grinding cylinder 2 is capable of self-rotation; a plurality of grinding balls are movably inserted in the grinding cylinder 2, and are configured to grind molybdenum ore; a plurality of lining plates 3 are inserted in the grinding cylinder 2, and are arranged on the inner circumferential wall of the grinding cylinder 2 at equal intervals along the circumferential direction; a shock absorbing part is provided on each lining plate 3, and the shock absorbing part is configured to absorb the kinetic energy of the grinding balls and the molybdenum ore; and the cleaning mechanism 4 is configured to regularly clean the molybdenum ore between two adjacent lining plates 3.

[0025] Specifically in this embodiment, Figure 4 and Figure 5 As shown, the grinding cylinder 2 is configured as a cylindrical structure with both ends opened. To facilitate closing the openings at both ends of the grinding cylinder 2, end covers 21 are connected to both ends of the grinding cylinder 2. The end cover 21 is configured as a T-shaped rotating body structure and has a vertically connected disc-shaped part and a columnar part, wherein the disc-shaped part and the grinding cylinder 2 are coaxially arranged, and the columnar part is located on the side of the disc-shaped part away from the grinding cylinder 2; to facilitate feeding into the grinding cylinder 2, a material port (not shown) is opened on the circumferential side wall of the grinding cylinder 2, and a cover plate 22 is closed at the material port, and the cover plate 22 is hinged on the grinding cylinder 2; to facilitate installation of the grinding cylinder 2, the ball mill for molybdenum ore processing is configured to also include a machine base 1, as shown in FIG. Figure 1 As shown, two fixed bearing seats 11 are symmetrically and spaced apart on the machine base 1 , and when the grinding cylinder 2 is installed, the columnar parts of the two end covers 21 are coaxial and respectively inserted into the two fixed bearing seats 11 .

[0026] like Figure 5 and Figure 6 As shown, the liner 3 is configured as a strip-shaped plate structure, and the end face of the liner 3 away from the axis of the grinding cylinder 2 is configured as an arc surface. When installed, the liner 3 is configured so that the extension direction is parallel to the axial direction of the grinding cylinder 2, and is detachably connected to the inner circumferential wall of the grinding cylinder 2 by bolts; taking the number of liner plates 3 as an example, the twelve liner plates 3 are inserted into the inside of the grinding cylinder 2 at equal intervals along the circumferential direction.

[0027] During installation, the layout of the plurality of lining plates 3 arranged at equal intervals along the circumferential direction allows the lining plates 3 to have a larger processing error, thereby facilitating an increase in the installation speed.

[0028] When grinding molybdenum ore, first open the cover plate 22, and then put the molybdenum ore into the grinding drum 2 through the material port. At this time, the layout of multiple lining plates 3 arranged at equal intervals along the circumferential direction allows the molybdenum ore to be relatively concentrated in the gap between two adjacent lining plates 3, so that in the subsequent grinding process, the thrown grinding balls can crush the concentrated molybdenum ore, which is beneficial to improve the crushing efficiency; then close the cover plate 22 to drive the grinding drum 2 to rotate; during the rotation of the grinding drum 2, the centrifugal force generated by the rotation of the grinding drum 2 brings the grinding balls to a certain height and then falls, so that the grinding balls can produce a heavy impact and grinding effect on the molybdenum ore, and the kinetic energy of the molybdenum ore and the grinding balls is then consumed by the shock absorbing part, which reduces the wear of the lining plates 3 and helps to extend the service life of the lining plates 3; at the same time, the cleaning mechanism 4 can regularly clean the molybdenum ore between two adjacent lining plates 3, so as to avoid the molybdenum ore from being stuck between two adjacent lining plates 3, which is beneficial to improve the overall grinding effect of the molybdenum ore.

[0029] In some embodiments, the damping unit is configured to include a plurality of first elastic damping plates 31 and a plurality of second elastic damping plates 32 , and the first elastic damping plates 31 and the second elastic damping plates 32 of the same damping unit are alternately arranged along the axial direction of the grinding drum 2 .

[0030] Specifically in this embodiment, Figure 7 As shown, taking the shock absorbing part as including seven first elastic shock absorbing plates 31 and seven second elastic shock absorbing plates 32 as an example, the seven first elastic shock absorbing plates 31 and the seven second elastic shock absorbing plates 32 on the same lining plate 3 are alternately arranged along the axial direction of the grinding drum 2, and the first elastic shock absorbing plates 31 on different lining plates 3 are correspondingly arranged and the second elastic shock absorbing plates 32 are correspondingly arranged.

[0031] During use, when molybdenum ore or grinding balls fall onto the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32, as the molybdenum ore or grinding balls continue to fall, the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 can undergo elastic compression deformation, thereby reducing the impact on the liner 3 by converting the kinetic energy of the molybdenum ore or grinding balls into the elastic potential energy of the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32.

[0032] In a further embodiment, the first elastic damping plate 31 can be set as an arc-shaped structure with the convex surface facing the axis of the grinding cylinder 2; the second elastic damping plate 32 can be set as a V-shaped structure with the small end facing the axis of the grinding cylinder 2.

[0033] When in use, since the first elastic shock-absorbing plate 31 is an arc-shaped structure and the second lining plate 3 is a V-shaped structure, the distance between the two corresponding first elastic shock-absorbing plates 31 on adjacent lining plates 3 is smaller than the distance between the two corresponding second elastic shock-absorbing plates 32, so that the dropped grinding balls are more easily distributed between the two corresponding second elastic shock-absorbing plates 32 on the two adjacent lining plates 3, and the grinding balls can be distributed more evenly in the axial direction, which is beneficial to improve the uniformity of the grinding balls in crushing molybdenum ore.

[0034] It is understandable that the first elastic shock absorbing plate 31 and the second elastic shock absorbing plate 32 may also be configured as an arc-shaped structure or a V-shaped structure.

[0035] In a further embodiment, the cleaning mechanism 4 is configured to include first transmission rods 41 and block groups, the number of which is equal to the number of liners 3. The block group is fixedly arranged on the inner circumferential wall of the grinding cylinder 2 and is located between two adjacent liners 3. Each block group is configured to include multiple first blocks 42, and the multiple first blocks 42 of the same block group are arranged at intervals along the axial direction of the grinding cylinder 2; the first transmission rod 41 is inserted between two adjacent liners 3, and the rod length direction extends along the axial direction parallel to the grinding cylinder 2, and simultaneously penetrates all the first blocks 42 of the same block group; each first transmission rod 41 is fixed with multiple second blocks 43 and spaced apart, and the second blocks 43 and the first blocks 42 on the same first transmission rod 41 are alternately arranged along the rod length direction of the first transmission rod 41; the first transmission rod 41 can move back and forth along its own rod length direction to push the molybdenum ore through the second block 43.

[0036] Specifically in this embodiment, taking the case where the number of first transmission rods 41 and block groups is twelve, the twelve first transmission rods 41 are respectively inserted between two adjacent lining plates 3, and the twelve block groups are respectively inserted between two adjacent lining plates 3; Figure 8 As shown, the first stopper 42 and the second stopper 43 are both configured as a rectangular parallelepiped structure with an arc bottom surface. When installed, the first stopper 42 and the second stopper 43 are configured to point to the axis of the grinding cylinder 2; Figure 7 As shown, the first transmission rod 41 is configured as a round rod structure. When installed, the first transmission rod 41 is configured to vertically penetrate the front and rear side walls of the first stop block 42 and the second stop block 43 .

[0037] More specifically, in order to facilitate the provision of driving force for the first transmission rod 41 to reciprocate along the length direction of the rod, the molybdenum ore processing ball mill is configured to further include a driving cylinder 12 and a first compression spring (not shown), such as Figure 2As shown, the drive cylinder 12 is arranged on the fixed bearing seat 11 on the left, and the output shaft of the drive cylinder 12 is arranged to the right in the horizontal direction, and a push plate is vertically and fixedly connected to the output shaft of the drive cylinder 12; the number of the first compression springs is equal to the number of the first transmission rods 41, and they are arranged one by one. When installed, the first compression spring is arranged on the right end surface of the grinding cylinder 2 and is fixedly connected to the right end portion of the first transmission rod 41, so as to drive the first transmission rod 41 to reset.

[0038] Initially, the second stopper 43 is disposed in contact with the previous first stopper 42 , so as to prevent molybdenum ore from accumulating between the second stopper 43 and the previous first stopper 42 .

[0039] During use, as the grinding drum 2 rotates, when the first transmission rod 41 rotates to the position of the driving cylinder 12, the output shaft of the driving cylinder 12 is synchronously extended; in the process of extending the output shaft of the driving cylinder 12, it first pushes on the end of the first transmission rod 41, and then synchronously drives the first transmission rod 41 to move inward. On the one hand, the first transmission rod 41 synchronously drives the second stop block 43 to move toward the direction of the next first stop block 42 to push the molybdenum ore between the second stop block 43 and the next first stop block 42, and on the other hand, drives the first compression spring to be compressed.

[0040] When the output shaft of the driving cylinder 12 extends to a preset length, the output shaft of the driving cylinder 12 begins to retract. During the retraction of the output shaft of the driving cylinder 12, the first transmission rod 41 moves outward synchronously under the push of the first compression spring until it returns to the initial position.

[0041] It can be understood that the driving cylinder 12 can be configured as any one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.

[0042] It is understandable that the first compression spring may not be provided, and a magnetic connection may be provided between the push plate and the first transmission rod 41 , so that the drive cylinder 12 can synchronously drive the first transmission rod 41 to move inward or outward.

[0043] In a further embodiment, the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 can both move along the circumference of the grinding cylinder 2, and the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 on the same liner 3 have a tendency to move in opposite directions, so as to achieve misalignment and increase the curvature of the first elastic shock-absorbing plate 31 and reduce the V-shaped angle of the second elastic shock-absorbing plate 32; the ball mill for processing molybdenum ore is configured to also include an adjustment mechanism 5, and the adjustment mechanism 5 is configured to be able to adjust the distance that the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 on the same liner 3 move in opposite directions according to the amount of molybdenum ore accumulated between two adjacent liner plates 3, so that the greater the amount of molybdenum ore accumulated between two adjacent liner plates 3, the greater the distance that the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 on the same liner 3 move in opposite directions.

[0044] Specifically in this embodiment, Fig. 9 As shown, the top surface of the lining plate 3 is set as a straight surface, and a plurality of sliding seats 33 are arranged on the straight surface. The plurality of sliding seats 33 are arranged at equal intervals along the extension direction of the lining plate 3. The sliding seat 33 is set as a strip-shaped block structure, and the cross-sectional shape is set to a T-shape. The extension direction of the sliding seat 33 is parallel to the extension direction of the short side of the top surface of the lining plate 3. A slide groove 331 is opened on the top of the sliding seat 33. The extension direction of the slide groove 331 is parallel to the extension direction of the sliding seat 33, and the slide groove 331 runs through the left and right side walls of the sliding seat 33. A third magnet 334 is fixedly arranged in the middle of the slide groove 331.

[0045] Two first mounting seats 311 are symmetrically arranged at the left and right ends of the bottom of the first elastic shock-absorbing plate 31. The first mounting seat 311 is set as a rectangular structure, and its long side extension direction is set parallel to the long side extension direction of the top surface of the lining plate 3. A T-shaped first sliding hole is penetrated on the left and right side walls of the first mounting seat 311. When installed, the first elastic shock-absorbing plate 31 is set to be slidably sleeved on the sliding seat 33 through the first sliding hole. A first magnet 312 is fixedly inserted at the first sliding hole. The first magnet 312 is slidably inserted in the sliding groove 331 when in use, and the two first magnets 312 on the same first elastic shock-absorbing plate 31 have the same magnetic pole facing the third magnet 334.

[0046] Two second mounting seats 321 are symmetrically arranged at the left and right ends of the bottom of the second elastic shock-absorbing plate 32. The second mounting seat 321 is set as a rectangular parallelepiped structure, and its long side extension direction is set parallel to the long side extension direction of the top surface of the lining plate 3. A T-shaped second sliding hole is penetrated on the left and right side walls of the second mounting seat 321. When installed, the first elastic shock-absorbing plate 31 is set to be slidably sleeved on the sliding seat 33 through the second sliding hole. A second magnet 322 is fixedly inserted at the second sliding hole. The second magnet 322 is slidably inserted in the sliding groove 331 when in use, and the two second magnets 322 on the same second elastic shock-absorbing plate 32 have the same magnetic pole facing the third magnet 334; the second mounting seat 321 has the same structure as the first mounting seat 311.

[0047] Taking the example of the third magnet 334 with the left side as the N pole and the right side as the S pole, at this time, the magnetic pole of the first magnet 312 on the left side facing the third magnet 334 and the magnetic pole of the first magnet 312 on the right side facing the third magnet 334 on the same first elastic shock-absorbing plate 31 can both be set to S poles, and under the action of magnetism, the first elastic shock-absorbing plate 31 has a tendency to move to the right; at this time, the magnetic pole of the second magnet 322 on the left side facing the third magnet 334 and the magnetic pole of the second magnet 322 on the right side facing the third magnet 334 on the same second elastic shock-absorbing plate 32 can both be set to N poles, and under the action of magnetism, the second elastic shock-absorbing plate 32 has a tendency to move to the left.

[0048] Similarly, at this time, the magnetic pole of the first magnet 312 on the left side facing the third magnet 334 and the magnetic pole of the first magnet 312 on the right side facing the third magnet 334 on the same first elastic shock-absorbing plate 31 can also be set to N poles, and the first elastic shock-absorbing plate 31 has a tendency to move to the left under the magnetic effect; at this time, the magnetic pole of the second magnet 322 on the left side facing the third magnet 334 and the magnetic pole of the second magnet 322 on the right side facing the third magnet 334 on the same second elastic shock-absorbing plate 32 can also be set to S poles, and the second elastic shock-absorbing plate 32 has a tendency to move to the right under the magnetic effect.

[0049] It is understandable that the left side of the third magnet 334 can also be set to the S pole, and the right side can also be set to the N pole, so that the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 on the same lining plate 3 have a tendency to move in opposite directions; the principle is the same as above and will not be repeated.

[0050] During use, when the amount of molybdenum ore accumulated between two adjacent lining plates 3 is larger, the longer the distance that the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 on the same lining plate 3 are moved in opposite directions by the adjustment mechanism 5, and the greater the degree of inward convexity of the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32, on the one hand, can improve the pushing ability of the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 on the molybdenum ore, and reduce the problem of poor grinding effect of the molybdenum ore due to the smaller particle size of the molybdenum ore and the difficulty in lifting in the later stage, and on the other hand, can increase the deformable amount of the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32, so as to improve the shock-absorbing ability of the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32; and can make the misalignment between the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 larger, so as to increase the shock-absorbing interval composed of the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32.

[0051] In a further embodiment, the adjustment mechanism 5 is configured to further include a transmission assembly 55, a second transmission rod 51 and a third transmission rod 52, the number of which is equal to the number of the lining plates 3, and the transmission assembly 55 and the first transmission rod 41 are arranged one by one; the second transmission rod 51 and the third transmission rod 52 are arranged in parallel with the first transmission rod 41, and can rotate on their own; a second transmission rod 51 and a third transmission rod 52 form a group, and the second transmission rod 51 and the third transmission rod 52 of the same group are respectively arranged on both sides of the same first transmission rod 41, and under the action of the transmission assembly 55, the second transmission rod 51 and the third transmission rod 52 of the same group can rotate in opposite directions; each second transmission rod 51 is sleeved with a plurality of Multiple first cams 53, the first cam 53 on the same second transmission rod 51 and the first elastic shock-absorbing plate 31 on the same lining plate 3 are correspondingly arranged, and when the second transmission rod 51 rotates, the first cam 53 can rotate synchronously in one direction to push the first elastic shock-absorbing plate 31 to increase the curvature of the first elastic shock-absorbing plate 31; each third transmission rod 52 is sleeved with multiple second cams 54 at intervals, the second cam 54 on the same third transmission rod 52 and the second elastic shock-absorbing plate 32 on the same lining plate 3 are correspondingly arranged, and when the third transmission rod 52 rotates, the second cam 54 can rotate synchronously in one direction to push the second elastic shock-absorbing plate 32 to reduce the V-shaped angle of the second elastic shock-absorbing plate 32.

[0052] Specifically in this embodiment, in order to facilitate the installation of the second transmission rod 51 and the third transmission rod 52, as shown in FIG. Fig. 9 As shown, two mounting holes 332 are symmetrically and vertically provided on the left and right ends of the sliding seat 33 and the front and rear side walls, as shown in FIG. Figure 6As shown, the second transmission rod 51 is set to be simultaneously inserted into the right-side mounting holes 332 of all the sliding seats 33 on the left side lining plate 3 during installation, the first cam 53 and the first elastic shock-absorbing plate 31 on the left side lining plate 3 are set in a one-to-one correspondence, and the first elastic shock-absorbing plate 31 has a tendency to move to the left under the push of the first cam 53. At this time, under the magnetic action of the first magnetic pole and the third magnetic pole, the first elastic shock-absorbing plate 31 has a tendency to move to the right so as to be able to press the first cam 53 tightly. The third transmission rod 52 is set to be simultaneously inserted into the left-side mounting holes 332 of all the sliding seats 33 on the right side lining plate 3 during installation, the second cam 54 and the second elastic shock-absorbing plate 32 on the right side lining plate 3 are set in a one-to-one correspondence, and the second elastic shock-absorbing plate 32 has a tendency to move to the right under the push of the second cam 54. At this time, under the magnetic action of the second magnetic pole and the third magnetic pole, the first elastic shock-absorbing plate 31 has a tendency to move to the right so as to be able to press the second cam 54 tightly.

[0053] like Figure 6 As shown, in order to facilitate the first cam 53 to rotate only in the counterclockwise direction and the second cam 54 to rotate only in the clockwise direction, the first cam 53 and the second transmission rod 51 are connected by a ratchet. When the second transmission rod 51 rotates in the counterclockwise direction under the cooperation of the ratchet, the first cam 53 can be synchronously driven to rotate in the counterclockwise direction. The second cam 54 and the third transmission rod 52 are connected by a ratchet. When the third transmission rod 52 rotates in the clockwise direction under the cooperation of the ratchet, the second cam 54 can be synchronously driven to rotate in the clockwise direction. Figure 7 , Figure 8 and Fig.10 As shown, a first collar 541 is coaxially and fixedly disposed on both sides of the large end of each second cam 54. The first collar 541 is rotatably sleeved on the outside of the third transmission rod 52. A first ratchet is disposed on the outer peripheral wall of each first collar 541. Fig. 9 As shown, two annular grooves 333 are coaxially arranged on the left and right sides of the slide groove 331 and the mounting hole 332, and a second ratchet is arranged on the circumferential side wall of the annular groove 333 on the right side, and the second ratchet and the first ratchet cooperate unidirectionally, so that the second cam 54 cannot rotate in the counterclockwise direction; similarly, second rings are coaxially and fixedly arranged on the left and right sides of the large end of each first cam 53, and the second ring can be rotatably sleeved on the outside of the second transmission rod 51 at the same time, and a third ratchet is arranged on the outer circumferential wall of each second ring; at this time, a fourth ratchet is arranged on the circumferential side wall of the annular groove 333 on the left side, and the fourth ratchet and the third ratchet cooperate unidirectionally, so that the first cam 53 cannot rotate in the clockwise direction.

[0054] During use, when the amount of molybdenum ore accumulated between two adjacent lining plates 3 is greater, the rotation angle of the second transmission rod 51 and the third transmission rod 52 is greater under the action of the transmission assembly 55, so that the rotation angle of the first cam 53 and the second cam 54 is greater, and thus the first mounting seat 311 on the right side of the first elastic shock-absorbing plate 31 moves to the left more. At this time, under the mutual attraction of the first magnet 312 and the third magnet 334, the moving distance of the first mounting seat 311 on the left side of the first elastic shock-absorbing plate 31 is less than the moving distance of the first mounting seat 311 on the right side, so that the first elastic shock-absorbing plate 31 becomes more convex; similarly, the greater the rotation angle of the second cam 54, the greater the distance the second mounting seat 321 on the left side of the second elastic shock-absorbing plate 32 moves to the right. At this time, under the mutual attraction of the second magnet 322 and the third magnet 334, the moving distance of the second mounting seat 321 on the right side of the second elastic shock-absorbing plate 32 is less than the moving distance of the second mounting seat 321 on the left side, so that the second elastic shock-absorbing plate 32 becomes more convex.

[0055] In a further embodiment, the transmission assembly 55 is configured to include a first gear 551, a second gear 552, a third gear 553 and a guide portion, the first gear 551 is sleeved on the first transmission rod 41, and can rotate relative to the first transmission rod 41, and can elastically slide along the rod length direction of the first transmission rod 41; the guide portion is configured to be able to adjust the rotation angle of the first gear 551, so that the rotation angle of the first gear 551 is adjusted to be larger when the amount of molybdenum ore accumulated between two adjacent liners 3 is larger; the third gear 553 is fixedly sleeved on the third transmission rod 52; the second gear 552 is fixedly sleeved on the second transmission rod 51, and is meshed with the first gear 551 and the third gear 553 at the same time.

[0056] Specifically in this embodiment, Figure 8 As shown, in order to facilitate the installation of the first gear 551, the ball mill for processing molybdenum ore is configured to also include a rotating seat 554, and the rotating seat 554 is configured as a "cross" shaped rotating body structure. The first gear 551 is configured to be rotatably sleeved on the rotating seat 554 during installation, and a mounting column is coaxially and fixedly arranged on the left end portion of the first transmission rod 41, and a second compression spring 555 is connected between the mounting column and the rotating seat 554.

[0057] During use, in the initial crushing stage of the molybdenum ore, very little powdered ore is produced, that is, the space between the second stopper 43 and the subsequent first stopper 42 will not be blocked, and the second compression spring 555 will basically not be compressed, so that the rotating seat 554 and the fixed column can move synchronously, at this time the first gear 551 will not rotate, and the second gear 552 and the third gear 553 will not rotate; when in the second half of the crushing of the molybdenum ore, the powdered ore will increase and be blocked between the second stopper 43 and the subsequent first stopper 42. As the grinding balls continue to fall, this part of the powdered ore is gradually compacted, so that the movement of the second stopper 43 has a large resistance, and the second compression spring 555 will be gradually compressed, so that the rotating seat 554 and the fixed column move relative to each other, and the first gear 551 rotates under the action of the guide part, synchronously driving the second gear 552 and the third gear 553 to rotate in the opposite direction, and then driving the first cam 53 and the second cam 54 thereon to rotate through the second transmission rod 51 and the third transmission rod 52.

[0058] In a further embodiment, the guide portion is configured to include a slidingly fitted protrusion and a guide groove 556 , wherein the protrusion is fixedly disposed on the inner circumferential wall of the first gear 551 ; the guide groove 556 is disposed on the first transmission rod 41 and includes a spiral groove 5563 .

[0059] Specifically in this embodiment, Figure 8 As shown, the guide groove 556 is configured to be composed of an annular groove 5561, a straight groove 5562 and a spiral groove 5563 which are connected in sequence, and the annular groove 5561, the straight groove 5562 and the spiral groove 5563 are arranged in sequence from left to right.

[0060] During use, in the initial crushing stage of the molybdenum ore, very little powdered ore is produced. At this time, the protrusion mainly moves in the straight groove 5562, and the first gear 551 does not rotate; when it is in the second half of the molybdenum ore crushing, the powdered ore increases. At this time, the protrusion mainly moves in the spiral groove 5563, so as to synchronously drive the first gear 551 to rotate.

[0061] In other embodiments, in order to improve the cleaning effect of the cleaning mechanism 4 , the position where the first transmission rod 41 reciprocates is set at the top of the grinding cylinder 2 .

[0062] Specifically in this embodiment, Figure 2 As shown, the driving cylinder 12 is arranged at the top of the left fixed bearing seat 11, so that during use, when the output shaft of the driving cylinder 12 drives the first transmission rod 41 to move inward synchronously, the molybdenum ore between the second stop block 43 and the next first stop block 42 can become loose under the pushing of the second stop block 43, and then this part of the molybdenum ore can fall to the maximum extent under the action of gravity, thereby improving the cleaning effect of the cleaning mechanism 4.

[0063] In other embodiments, the ball mill for processing molybdenum ore is configured to further include a driving mechanism 6 , and the driving mechanism 6 is configured to provide a driving force for the self-rotation of the grinding cylinder 2 .

[0064] Specifically in this embodiment, the driving mechanism 6 is configured to include a driving motor 61, a first pulley 62, a second pulley 63 and a transmission belt 64. Figure 1 As shown, the driving motor 61 is installed on the machine base 1, the first pulley 62 is fixedly sleeved on the motor shaft of the driving motor 61, the second pulley 63 is fixedly sleeved on the outer peripheral wall of the grinding cylinder 2, and the transmission belt 64 is transmission sleeved between the first pulley 62 and the second pulley 63.

[0065] When in use, the driving motor 61 is started, the driving motor 61 drives the first pulley 62 to rotate, the first pulley 62 drives the second pulley 63 to rotate through the transmission belt 64, and the second pulley 63 drives the grinding drum 2 to rotate.

[0066] In combination with the above embodiments, the use principle and working process of the embodiments of the present invention are as follows: When grinding molybdenum ore, first open the cover plate 22, and then put the molybdenum ore into the grinding cylinder 2 through the material port; then start the drive motor 61, the drive motor 61 drives the first pulley 62 to rotate, the first pulley 62 drives the second pulley 63 to rotate through the transmission belt 64, and the second pulley 63 drives the grinding cylinder 2 to rotate; during the rotation of the grinding cylinder 2, the centrifugal force generated by the rotation of the grinding cylinder 2 brings the grinding balls to a certain height and then falls, so that the grinding balls can produce a heavy impact and grinding effect on the molybdenum ore; and when the molybdenum ore or grinding balls fall onto the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32, as the molybdenum ore or grinding balls continue to fall, the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32 can undergo elastic compression deformation, so that the kinetic energy of the molybdenum ore or grinding balls can be converted into elastic potential energy of the first elastic shock-absorbing plate 31 and the second elastic shock-absorbing plate 32.

[0067] In the initial crushing stage of the molybdenum ore, very little powdered ore is produced, that is, the space between the second stopper 43 and the next first stopper 42 will not be blocked, and the second compression spring 555 will basically not be compressed, so that the rotating seat 554 and the fixed column can move synchronously. At this time, the protrusion mainly moves in the straight groove 5562, the first gear 551 will not rotate, and the second gear 552 and the third gear 553 will not rotate; when it is in the second half of the molybdenum ore crushing, the powdered ore will increase and be blocked between the second stopper 43 and the next first stopper 42. As the grinding balls continue to fall, the powdered ore will be blocked between the second stopper 43 and the next first stopper 42. Part of the powdered ore is gradually compacted, so that the movement of the second stopper 43 has a large resistance, and the second compression spring 555 is gradually compressed, so that relative movement occurs between the rotating seat 554 and the fixed column. At this time, the protrusion mainly moves in the spiral groove 5563, so as to be able to synchronously drive the first gear 551 to rotate in the clockwise direction. The first gear 551 synchronously drives the second gear 552 to rotate in the counterclockwise direction and the third gear 553 to rotate in the clockwise direction, and then drives the first cam 53 and the second cam 54 thereon to rotate through the second transmission rod 51 and the third transmission rod 52.

[0068] The first cam 53 rotates to cause the first mounting seat 311 on the right side of the first elastic shock-absorbing plate 31 to move to the left. At this time, under the mutual attraction of the first magnet 312 and the third magnet 334, the moving distance of the first mounting seat 311 on the left side of the first elastic shock-absorbing plate 31 is smaller than the moving distance of the first mounting seat 311 on the right side, so that the first elastic shock-absorbing plate 31 becomes more convex; similarly, the second cam 54 rotates to cause the second mounting seat 321 on the left side of the second elastic shock-absorbing plate 32 to move to the right. At this time, under the mutual attraction of the second magnet 322 and the third magnet 334, the moving distance of the second mounting seat 321 on the right side of the second elastic shock-absorbing plate 32 is smaller than the moving distance of the second mounting seat 321 on the left side, so that the second elastic shock-absorbing plate 32 becomes more convex.

[0069] During the rotation of the grinding drum 2, when the first transmission rod 41 rotates to the position of the driving cylinder 12, the output shaft of the driving cylinder 12 is synchronously extended; during the extension of the output shaft of the driving cylinder 12, it first pushes on the end of the first transmission rod 41, and then synchronously drives the first transmission rod 41 to move inward. On the one hand, the first transmission rod 41 synchronously drives the second stop block 43 to move toward the direction of the next first stop block 42 to push the molybdenum ore between the second stop block 43 and the next first stop block 42, and on the other hand, drives the first compression spring to compress; at the same time, the protrusion will move along the spiral groove 5563 and away from the end of the straight groove 5562, so that the first cam 53 and the second cam 54 are both rotated 360 degrees, so as to facilitate the deformation of the first elastic damping plate 31 and the second elastic damping plate 32 respectively next time.

[0070] When the output shaft of the driving cylinder 12 extends to a preset length, the output shaft of the driving cylinder 12 begins to retract. During the retraction of the output shaft of the driving cylinder 12, the first transmission rod 41 moves outward synchronously under the push of the first compression spring until it returns to the initial position; at the same time, the protrusion will move along the spiral groove 5563 and into the straight groove 5562, and the first gear 551 rotates counterclockwise, driving the second gear 552 to rotate in the clockwise direction and the third gear 553 to rotate counterclockwise. Under the unidirectional cooperation of the second ratchet and the first ratchet, the second cam 54 will not rotate with it, and under the unidirectional cooperation of the third ratchet and the fourth ratchet, the first cam 53 will not rotate with it.

[0071] After the grinding is completed, the cover plate 22 is opened, and then the ground molybdenum ore in the grinding cylinder 2 is taken out through the material opening.

[0072] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
