Description

Technical Field

[0001] The invention relates to the technical field of ball mills, in particular to a high-efficiency mill for mineral processing. Background Art

[0002] A ball mill is a key piece of equipment for pulverizing materials after crushing. This type of mill uses a cylinder filled with a predetermined number of grinding balls as the grinding medium. It is widely used in industries such as cement, silicate products, new building materials, refractories, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics for dry or wet grinding of various ores and other grindable materials. A ball mill consists of a horizontal cylinder, hollow feed and discharge shafts, and a grinding head. The cylinder is a long, cylindrical structure containing the grinding media. Material is fed into the cylinder through the hollow feed shaft. As the cylinder rotates, the grinding media, due to inertia and centrifugal force, adhere to the cylinder liner and are carried away by the cylinder. When carried to a certain height, they are thrown down by gravity, acting like projectiles and crushing the material within.

[0003] Publication number CN114588974A discloses a stirring ball mill, including a support seat, a bearing, a rotating drum and a guide grinding assembly. The support seats are relatively distributed, and the bearings are fixedly installed on the support seats respectively. The bearings are relatively arranged, and the two ends of the rotating drum are rotatably installed between the bearings through a rotating shaft. The guide grinding assembly is arranged in the rotating drum, and the guide grinding assembly includes an arc-shaped guide plate, grinding balls and a guide channel. The arc-shaped guide plate is fixedly installed between the two ends of the rotating drum, and the arc-shaped guide plate is distributed in a ring-shaped manner around the central axis direction of the rotating drum. A guide channel is formed between the arc-shaped guide plate and the inner wall of the rotating drum. The grinding balls are fixedly assembled on the inner wall of the rotating drum, and the grinding balls are evenly spaced. When the rotating drum rotates, the grinding balls and the arc-shaped guide plate rotate synchronously with the rotating drum. During the rotation process, the material collides with the grinding balls and is dispersed and ground in the rotating drum through any guide channel, thereby improving the grinding effect and improving the grinding efficiency.

[0004] A similar technical solution to the above improves the grinding effect by adding an arc-shaped guide plate inside the ball mill to guide and disperse the material in the rotating drum for grinding, but the throwing trajectory of the grinding material is relatively constant, which makes it inconvenient to adjust the throwing trajectory of the material and the grinding body, resulting in an inability to guarantee the probability of collision between the material and the grinding body, thereby affecting the grinding effect of the material. At the same time, when adding grinding balls, the landing points of the grinding balls are uneven, resulting in poor mixing uniformity between the grinding balls and the material, which also affects the grinding efficiency.

[0005] Therefore, it is necessary to invent a high-efficiency grinding mill for mineral processing to solve the above problems. Summary of the Invention

[0020] The technical effects and advantages of the present invention are as follows:

[0021] 1. The present invention provides a cylinder assembly, and a first liner and a second liner are provided inside the cylinder assembly. The first liner and the second liner can play a role in assisting the throwing of materials to improve the grinding effect of the materials. A protrusion is provided on the outer side of the first liner, and inclined surfaces with different inclinations are provided on both sides of the protrusion.

A protrusion with an inclined structure is provided on the outer side of the second liner. Under the guidance of the protrusion, the materials and the grinding balls can rotate to a certain extent, thereby improving the grinding effect of the materials when they fall and collide, thereby improving the grinding effect of the device.

[0022] 2. The present invention sets a cylinder assembly, and both ends of the cylinder assembly are provided with end plate assemblies. The inner side of the end plate assembly is provided with an arc-shaped guide plate. When the material moves to a certain height, the guide plate can guide the material so that the material moves along the inner wall of the guide plate under the action of inertia, thereby changing the movement trajectory of the material to increase the throwing range of the material, thereby achieving the effect of improving the grinding effect, and the angle of the guide plate can be adjusted so that the device can be adaptively adjusted according to the grinding standard of the material.

[0023] 3. The present invention provides a first guide plate which is low in the middle and high at both ends, a second guide plate which is low on the left and high on the right, and a third guide plate which is high on the left and low on the right. This allows the material and the grinding balls to be offset laterally toward the middle, left end, and right end of the movable cylinder on the basis of the original vertical throwing. This allows the material to be thrown along trajectories that are obliquely to the right and obliquely to the left at the same time, and can also be thrown along trajectories that are obliquely to the left and obliquely to the right toward the middle, thereby achieving the purpose of throwing the material and the grinding balls along trajectories in different directions. At the same time, the throwing height of the material and the grinding balls is also increased, thereby increasing the collision probability and force between the material and the grinding balls, and ensuring the grinding effect of the material.

[0024] 4. The present invention guides the added grinding balls by adjusting the first guide plate, the second guide plate and the third guide plate to an angle where the arc surface faces the delivery channel, so that the added grinding balls can move toward the middle, left end and right end of the movable cylinder respectively, thereby improving the dispersion of the grinding balls during the falling process, so that the material and the grinding balls can be evenly mixed in the movable cylinder, thereby ensuring that the material and the grinding balls can be quickly and evenly mixed, shortening the time required for grinding, and improving the grinding efficiency of the material.

[0025] 5. The present invention sets an adjustment component, which can realize the connection between the end plate assembly and the cylinder assembly. By adjusting the adjustment component, the limit between the end plate assembly and the cylinder assembly can be released to facilitate the disassembly of the end plate assembly, thereby facilitating the cleaning, maintenance and unloading inside the device.

The protrusions 109 can guide the material and the grinding balls so that the material and the grinding balls rotate to a certain extent to improve the grinding effect of the material.

[0052] The end plate assembly 2 includes two movable plates 201, and the two movable plates 201 are respectively arranged inside the two connecting seats 103; specifically, a stepper motor 202 is fixedly arranged on the outer side of the movable plate 201 on the left, and a support rod 203 is fixedly arranged on the power output end of the stepper motor 202. The support rod 203 passes through the interior of the movable cylinder 101, and the other end of the support rod 203 is rotatably arranged on the movable plate 201 on the right through a bearing. A guide plate 204 is fixedly arranged on the outer side of the support rod 203, and the guide plate 204 can guide the material and the grinding balls.

[0053] More specifically, the guide plate 204 is configured as an arc structure, and the inner arc surface of the guide plate 204 is provided with a plurality of hemispherical fixed blocks 205, and sealing plates 206 are fixedly provided at both ends of the guide plate 204, and the sealing plates 206 are in contact with the inner wall of the movable plate 201.

[0054] The adjustment component 3 includes a mounting seat 301, and the mounting seat 301 is arranged in the middle of the outer side of the movable plate 201 located on the right side; specifically, connecting ears 302 are fixedly provided on both sides of the mounting seat 301, and the connecting ears 302 are fixedly provided in the middle of the outer side of the movable plate 201 by bolts, and both ends of the mounting seat 301 are penetrated by a plug 303, and the inside of the plug 303 is penetrated by an insertion rod 304, and one end of the insertion rod 304 is fixedly provided with a positioning seat 305, and the positioning seat 305 is in contact with the inner wall of the connecting seat 103.

[0055] More specifically, a rotating seat 306 is provided inside the mounting seat 301, and connecting blocks 307 are fixedly provided on both sides of the rotating seat 306, and two movable arms 308 are provided on the outer side of the connecting block 307 through a pin shaft, and one end of the movable arm 308 is movably provided on one end of the insertion rod 304 through a pin shaft, and the rotating seat 306 can drive the insertion rod 304 to move through the movable arm 308.

[0056] In addition, a bracket 314 is fixedly provided on the inner side wall of the mounting seat 301, and the rotating seat 306 is rotatably provided on the outer side of the bracket 314. A hexagonal groove 309 is provided through the middle of the rotating seat 306, and a hexagonal shaft 310 is provided through the inside of the hexagonal groove 309. A spline shaft 311 is fixedly provided on one end of the hexagonal shaft 310, and a sleeve 312 is sleeved on one end of the spline shaft 311. The sleeve 312 is fixedly provided on the inner side wall of the mounting seat 301. When the spline shaft 311 is inserted into the sleeve 312, it cannot rotate, and the rotating seat 306 can be realized at this time. The limit is achieved by locking the adjustment component 3, and a tension spring is provided inside the sleeve 312, one end of the tension spring is fixedly connected to the inner wall of the sleeve 312, and the other end of the tension spring is fixedly connected to the spline shaft 311. The setting of the tension spring ensures that the spline shaft 311 is automatically inserted into the sleeve 312 when not subjected to external force, thereby achieving the limit of the rotating seat 306. An auxiliary handwheel 313 is fixedly provided at one end of the hexagonal shaft 310, and the auxiliary handwheel 313 is provided on the outside of the mounting seat 301. The auxiliary handwheel 313 facilitates the user to operate the hexagonal shaft 310.

[0057] The driving assembly 4 includes a base 401, and the base 401 is arranged at the bottom end of the movable cylinder 101. A driving motor 402 is fixedly provided in the middle of the base 401, and the output shaft of the driving motor 402 is fixedly provided with a driving gear 403 corresponding to the transmission gear 102; specifically, support shafts 404 are provided at both ends of the upper surface of the base 401, and support rollers 405 are provided at both ends of the support shaft 404, and the support rollers 405 correspond to the movable cylinder 101, and the support rollers 405 can play a supporting role for the movable cylinder 101.

[0058] In summary, when the device is in use, the material and the grinding balls are put into the interior of the cylinder assembly 1, and the driving assembly 4 can drive the cylinder assembly 1 to rotate. When the cylinder assembly 1 rotates, it can drive the material and the grinding balls to move, so that the material and the grinding balls move to a high place and fall down. During this process, the material and the grinding balls continuously collide to achieve the grinding of the material. During the material conveying and throwing process, the end plate assembly 2 can guide the movement of the material to increase the throwing range of the material, thereby improving the grinding effect of the material, and the adjustment assembly 3 can limit the end plate assembly 2 to facilitate the disassembly and unloading of the end plate assembly 2.

[0059] When the cylinder assembly 1 is grinding the material, the driving motor 402 drives the transmission gear 102 to rotate through the driving gear 403, and the transmission gear 102 drives the movable cylinder 101 to rotate, so that the movable cylinder 101 rotates, and the movable cylinder 101 can drive the first lining plate 104 and the second lining plate 105 to rotate. The first lining plate 104 drives the material to move through the protrusions 106 on its surface, so that the material and the grinding balls are brought to a higher place, and the protrusions 109 on the surface of the second lining plate 105 can also drive the material and the grinding balls to move, and the material and the grinding balls can move along the inclined surface of the protrusions 109, so that the material and the grinding balls rotate to a certain extent. When the material and the grinding balls move to a certain height, they change their motion trajectory under the guidance of the guide plate 204. Under the action of inertia, the material and the grinding balls move a certain distance along the inner wall of the guide plate 204, and then perform parabolic motion under the action of gravity and inertia. During the movement, the material and the grinding balls collide multiple times to achieve material grinding.

[0060] The barrel assembly 1 can rotate in two directions under the action of the driving motor 402. When the barrel assembly 1 rotates in two directions, the first inclined surface 107 and the second inclined surface 108 can guide and transport the material in different directions. Since the inclinations of the first inclined surface 107 and the second inclined surface 108 are different, they can guide and transport the material at different heights, thereby achieving different crushing effects.

[0061] When adjusting the guide plate 204 in the end plate assembly 2, start the stepper motor 202. At this time, the stepper motor 202 will drive the support rod 203 to rotate, so that the support rod 203 drives the guide plate 204 to rotate synchronously. When the guide plate 204 is adjusted to a suitable angle, turn off the stepper motor 202, and the guide plate 204 will be fixed in the current position, thereby realizing the adjustment of the angle of the guide plate 204, thereby facilitating the guide plate 204 to guide the material.

[0062] When adjusting the adjustment component 3, first pull the auxiliary handwheel 313 so that the auxiliary handwheel 313 drives the hexagonal shaft 310 and the spline shaft 311 to move outward. At this time, the spline shaft 311 is separated from the sleeve 312, and the limit of the spline shaft 311 is released. At this time, the hexagonal shaft 310 and the spline shaft 311 are rotated, and the hexagonal shaft 310 drives the rotating seat 306 to move. The rotating seat 306 drives the insertion rod 304 to move through the movable arm 308, so that the positioning seat 305 at one end of the insertion rod 304 is separated from the connecting seat 103. At this time, the limit of the adjustment component 3 and the connecting seat 103 can be released, thereby releasing the limit between the end plate assembly 2 and the cylinder assembly 1.

[0063] Example 2

[0064] In the above embodiment, by means of the inclined surfaces with different inclinations on both sides of the protrusion 106, when the barrel assembly 1 rotates in different directions, the two inclined surfaces can bring the material to different heights, so as to adapt to the grinding of materials with different grinding standards. At the same time, through the guidance of the protrusion 109, the material and the grinding balls rotate to a certain extent during the movement, thereby improving the grinding effect when the material falls and collides. In addition, by providing an arc-shaped structure guide plate 204 with an adjustable angle, the material and the grinding balls are guided, thereby changing the movement trajectory of the material and the grinding balls, and increasing the throwing range of the material and the grinding balls, thereby achieving the effect of improving the grinding effect. Although the arc-shaped guide plate 204 can change the movement trajectory of the material and the grinding balls and increase the throwing range, in the process of the material and the grinding balls being thrown along the guide plate 204, the throwing trajectory of the material and the grinding balls is always on the vertical plane perpendicular to the guide plate 204, that is, the material and the grinding balls can only be thrown out vertically, which causes the material and the grinding balls to always be thrown out with a fixed trajectory, which is not conducive to increasing the collision probability between the material and the grinding balls, thereby affecting the grinding effect of the material. At the same time, when adding grinding balls or materials to the movable cylinder 101, the grinding balls or materials will fall directly and accumulate in the movable cylinder 101, which is not conducive to the full mixing between the grinding balls and the materials, resulting in a low mixing uniformity between the grinding balls and the materials. The movable cylinder 101 needs to rotate for a long time before the grinding balls and the materials are evenly mixed, resulting in a long grinding time and low grinding efficiency. Therefore, the solution of the present invention is further improved so that the material and the grinding balls are thrown out along different trajectories, that is, the material and the grinding balls are laterally offset in the process of being thrown out vertically, thereby changing the throwing trajectory of the material and the grinding balls, thereby increasing the probability of collision between the material and the grinding balls, and improving the grinding effect of the material. Moreover, when adding grinding balls or materials into the movable cylinder 101, the falling grinding balls and materials can be guided to increase the dispersion of the grinding balls and materials during the falling process, so that the grinding balls and materials can fall evenly into the movable cylinder 101, thereby ensuring that the material and the grinding balls can be quickly and evenly mixed, thereby shortening the time required for grinding and improving the grinding efficiency of the material.

[0065] Specifically, such as Figure 2 and Figures 14 to 20As shown, the guide plates 204 are provided with three, namely the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043, and the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043 are all provided with an arc structure, the first guide plate 2041 is a two-way slope structure with a low middle part and high two ends, and the material and the grinding balls thereon will move toward the middle part, the second guide plate 2042 is a one-way slope structure with a low left end and a high right end, and the material and the grinding balls thereon will move toward the left end, and the third guide plate 2043 is a one-way slope structure with a high left end and a low right end, and the material and the grinding balls thereon will move toward the right end. The plates 2043 are all evenly rotated and arranged inside the movable cylinder 101 through the support rod 203, and the lengths of the second guide plate 2042 and the third guide plate 2043 are both two-thirds of the length of the support rod 203, that is, there is enough gap between the left end of the second guide plate 2042 and the right end of the third guide plate 2043 and the movable plate 201 on the corresponding side, so that the material and grinding balls can fall from the left end of the second guide plate 2042 and the right end of the third guide plate 2043 respectively, preventing material from remaining on the second guide plate 2042 and the third guide plate 5043 during unloading, and at the same time preventing the material and grinding balls from being guided to the two ends inside the movable cylinder 101, preventing the material and grinding balls from accumulating at the two ends inside the movable cylinder 101.

[0066] More specifically, a gear ring 5 is rotatably provided on the outer side of the movable plate 201 located on the left side, and the gear ring 5 can rotate on one side of the movable plate 201 located on the left side. One end of the three support rods 203 is fixedly provided with a driven gear 6, and the three driven gears 6 are all meshed with the gear ring 5. One end of the support rod 203 located on the second guide plate 2042 is fixedly connected to the power output shaft of the stepper motor 202. When the power output shaft of the stepper motor 202 rotates, it will drive the support rod 203 to rotate. At this time, the support rod 203 will rotate synchronously through the driven gear 6 thereon, so that the driven gear 6 drives the gear ring 5 to rotate. When the gear ring 5 rotates, it will drive the other two driven gears 6 to rotate synchronously, thereby causing the other two support rods 203 to rotate synchronously. Then, the stepper motor 202 drives the three support rods 203 to rotate synchronously at the same time, and finally achieves synchronous adjustment of the angles of the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043.

[0067] It should be noted that, during the grinding process of the material, the initial positions of the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043 are adjusted by the stepping motor 202 so that one side of the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043 are close to the inner wall of the movable cylinder 101. Figure 19As shown, at this time, the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043 throw the material and the grinding balls, and on the basis of throwing the material and the grinding balls vertically, the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043 can cause the material and the grinding balls to be laterally offset, that is, when the first guide plate 2041 throws the material and the grinding balls, the material and the grinding balls are offset laterally toward the middle of the movable cylinder 101 on the basis of throwing them vertically, so that The material and the grinding balls are thrown along the trajectories obliquely to the right and obliquely to the left at the same time. When the second guide plate 2042 throws the material and the grinding balls, the material and the grinding balls are thrown vertically and at the same time offset horizontally toward the left end of the movable cylinder 101, so that the material is thrown along the trajectory obliquely to the left. When the third guide plate 2043 throws the material and the grinding balls, the material and the grinding balls are thrown vertically and at the same time offset horizontally toward the right end of the movable cylinder 101, so that the material is thrown along the trajectory obliquely to the right.

[0068] By providing a first guide plate 2041 which is low in the middle and high at both ends, a second guide plate 2042 which is low on the left and high on the right, and a third guide plate 2043 which is high on the left and low on the right, the material and the grinding balls can be offset laterally toward the middle, left end, and right end of the movable cylinder 101 on the basis of the original vertical throwing, so that the material can be thrown along the trajectories obliquely to the left and obliquely to the right to the middle at the same time, or can be thrown along the trajectories obliquely to the left and obliquely to the right separately, thereby achieving the purpose of throwing the material and the grinding balls along trajectories in different directions, and at the same time increasing the throwing height of the material and the grinding balls, thereby increasing the collision probability and force between the material and the grinding balls, and ensuring the grinding effect of the material.

[0069] Example 3

[0070] During the grinding process, material and grinding balls are added to the movable cylinder 101. To ensure the grinding effect, it is necessary to improve the uniformity of the distribution of the newly added material and grinding balls within the movable cylinder 101. Based on the above embodiment, the initial positions of the first guide plate 2041, the second guide plate 2042, and the third guide plate 2043 are adjusted to improve the uniformity of the distribution of the newly added material and grinding balls within the movable cylinder 301, thereby improving the grinding effect.

[0071] Specifically, such as Figure 2 and Figure 20 As shown, a delivery port 7 is provided on the movable plate 201 on the left side, and a delivery channel extending to the interior of the movable cylinder 101 is fixedly provided at one end of the delivery port 7. Materials and grinding balls can be added into the movable cylinder 101 through the delivery port 7 and the delivery channel.

[0072] Before adding materials and grinding balls into the movable cylinder 101 through the feeding port 7, the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043 are adjusted by the stepping motor 202 to an angle where the arc surface faces the feeding channel. Specifically, Figure 20 As shown, as the movable cylinder 101 continues to rotate, the material and grinding balls will fall onto the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043 respectively during the adding process. When the material and grinding balls fall onto the first guide plate 2041, the first guide plate 2041 will guide the material and grinding balls so that the material and grinding balls move toward the middle of the movable cylinder 101. When the material and grinding balls fall onto the second guide plate 2042, the second guide plate 2042 guides the material and grinding balls so that the material and grinding balls move toward the left end of the movable cylinder 101. When the material and grinding balls fall onto the third guide plate 2043, the third guide plate 2043 guides the material and grinding balls so that the material and grinding balls move toward the right end of the movable cylinder 101.

[0073] Moreover, if Figure 20 As shown, when the first guide plate 2041, the second guide plate 2042, and the third guide plate 2043 are positioned around the periphery of the delivery channel, as the movable cylinder 301 drives the internal material to rise and fall, the fallen material can first impact the back of the first guide plate 2041, the second guide plate 2042, and the third guide plate 2043, and then slide into the movable cylinder 301. In this way, the thrown material can experience two impacts, which can improve the grinding effect of the material. Of course, in order to ensure the grinding effect of the material in this state, grinding blocks can be provided on the back of the first guide plate 2041, the second guide plate 2042, and the third guide plate 2043 to improve the grinding effect when the material impacts on them.

[0074] As described above, by adjusting the first guide plate 2041, the second guide plate 2042 and the third guide plate 2043 to the angle where the arc surface is facing the delivery channel, the added material and grinding balls are guided so that the added material and grinding balls can move toward the middle, left end and right end of the movable cylinder 101 respectively, thereby improving the dispersion of the material and grinding balls during the falling process, so that the material and grinding balls can fall evenly into the movable cylinder 101, thereby ensuring that the material and grinding balls can be quickly and evenly mixed, shortening the time required for grinding, and improving the grinding efficiency of the material.

[0075] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
