Description

Technical Field

[0001] The present invention relates to the technical field of accessories for semi-autogenous mills, and particularly to a combined lining plate assembly for a semi-autogenous mill. Background Art

[0002] In metal ore dressing plants, autogenous mills or semi-autogenous mills are often used to finely crush coarse crushed materials. Inside an autogenous mill or a semi-autogenous mill, the materials generally have two movement forms: throwing and discharging, and there are also two types of crushing actions: impact crushing and rubbing and peeling crushing. After the materials or grinding media (steel balls) are lifted by the lining plate lifting bars and then fall under the action of gravity onto the materials or the lining plate at the toe of the autogenous mill or semi-autogenous mill, causing the materials to break. And the materials or grinding media that make the discharging movement have a rubbing and peeling effect on each other, so that the materials are crushed through the rubbing and peeling effect. Generally speaking, the main way of material crushing inside an autogenous mill or a semi-autogenous mill is impact crushing. Impact crushing causes the lining plates of the autogenous mill or semi-autogenous mill to be damaged relatively quickly, and its grinding efficiency or operation rate is often the key factor restricting the production capacity of an ore dressing plant. With the progress of equipment manufacturing technology and the development of ore dressing processes, autogenous mills and semi-autogenous mills are developing towards large-scale, the upper limit of the particle size of the incoming materials is gradually increasing, the size of the grinding media (steel balls) is also correspondingly increasing, and higher requirements are put forward for the structural strength, wear resistance and grinding efficiency of the lining plates of large autogenous mills and semi-autogenous mills.

[0003] Most of the existing lining plates of semi-autogenous mills are installed by direct fixing through welding or bolts. However, although welding installation can ensure its installation strength, the installation process is cumbersome and not conducive to the replacement of the lining plates. And although fixing by bolts can improve the disassembly and assembly efficiency, the bolts will loosen or deform due to the collision of the materials inside the semi-autogenous mill, which is not conducive to long-term use. Moreover, the existing lining plates of semi-autogenous mills have limited crushing effect on the materials, and only the crushing accuracy of the materials can be controlled by changing the processing time. Therefore, it is very necessary to invent a combined lining plate assembly for a semi-autogenous mill to solve the above problems. Summary of the Invention

[0018] The technical effects and advantages of the present invention:

[0019] 1. The present invention provides a mounting assembly and a liner base. The mounting assembly can be fixed to the inner wall of the inner cylinder of the semi-autogenous mill by bolts or welding, and the liner base can be installed on the mounting assembly by means of snap-fit ​​and bolt cooperation. The hexagon socket bolts for connecting the liner base and the mounting assembly are hidden inside the liner base and will not be affected by the material. The liner base is installed in this way, which facilitates the disassembly and assembly of the liner base while ensuring its installation strength. At the same time, two adjacent mounting assemblies are staggered, so that the connection force points between the mounting assembly and the inner wall of the inner cylinder of the semi-autogenous mill are staggered, thereby effectively improving the force load of the mounting assembly and the liner base.

[0020] 2. The present invention sets a liner base, and a positive force-bearing surface and a reverse force-bearing surface are respectively set on both sides of the liner base. When the semi-autogenous mill rotates forward, the positive force-bearing surface can push the material and bear the impact of the material. When the semi-autogenous mill rotates reversely, the reverse force-bearing surface can push the material and bear the impact of the material. By switching the running direction of the semi-autogenous mill, the two sides of the liner base can be used to process the material separately, thereby improving the service life of the liner base.

[0021] 3. The present invention sets a positive force-bearing surface and a reverse force-bearing surface. The positive force-bearing surface is composed of a first force-bearing surface, a second force-bearing surface and a third force-bearing surface. The reverse force-bearing surface is composed of a first inclined surface, a second inclined surface and a second spliced ​​inclined surface. The inclination angle of the first force-bearing surface is smaller than that of the first inclined surface. Therefore, when the semi-autogenous mill rotates forward, the material is pushed to a higher height and the drop of the material is larger. Moreover, the positive force-bearing surface is provided with a stepped second force-bearing surface and a third force-bearing surface. Therefore, the positive force-bearing surface can realize the crushing processing of large pieces of material, and the reverse force-bearing surface can realize the fine grinding processing of the material. By switching the running direction of the semi-autogenous mill, the material processing effect can be controlled.

[0022] 4. The present invention sets a first air supply area and makes it cooperate with the inner cylinder, the first channel and the second channel on the liner base, the blowing holes and other components. When crushing large-particle materials, the high-pressure blowing provided by the first air supply area can, on the one hand, impact the sliding large-particle materials to play a crushing role, and can make the large-particle materials loose, increase the falling area of ​​the large-particle materials after falling, increase the total crushing area of ​​the large-particle materials, and thus improve the large-particle crushing effect; on the other hand, the high-pressure wind can lift up the fine particles mixed in the large-particle materials, and discharge and collect them through the exhaust system to prevent the materials from being over-crushed; furthermore, the impact of the high-pressure wind on the sliding large-particle materials can accelerate the large-particle materials to move downward, and the large-particle materials can move downward at a higher speed and impact on the crushing surface, thereby greatly improving the crushing effect of the large-particle materials and improving the crushing efficiency of the large-particle materials, and the effect is particularly significant.

[0023] 5. By setting up the second air supply area and making it cooperate with components such as the inner cylinder body, the first and second channels on the liner base, and the blowing holes, when crushing small particle materials, the high-pressure blowing provided by the second air supply area can, on the one hand, further disperse the falling small particle materials, increasing the dispersion area, thereby increasing the crushing area and improving the crushing effect; on the other hand, after the materials meeting the crushing particle size in the further dispersed small particle materials are lifted, they can be discharged and collected by the exhaust system, preventing the small particle materials meeting the crushing particle size from being over-crushed; furthermore, after the materials meeting the crushing particle size are separated in time, the crushing effect of the remaining small particle materials can be improved, thereby enhancing the crushing efficiency of the small particle materials, and the effect is particularly remarkable.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1

[0038] The present invention provides a combined semi-autogenous mill lining plate assembly as Figures 1 to 11 shown, which includes a mounting component 1, a lining base 2, a forward stress surface 3 and a reverse stress surface 4. There are multiple mounting components 1, and the multiple mounting components 1 form an annular structure, and two adjacent mounting components 1 are distributed in a staggered manner. The lining base 2 is located above the mounting component 1, and the forward stress surface 3 and the reverse stress surface 4 are respectively arranged on both sides of the lining base 2.

[0039] The mounting component 1 includes a mounting base 101. In the middle of the upper surface of the mounting base 101, a fixing base 102 is fixedly connected. The fixing base 102 is arranged in a "concave" structure. At both top ends of the fixing base 102, first inclined surfaces 103 are provided. In the middle of the upper surface of the fixing base 102, a slot 104 is opened. The slot 104 is arranged in a circular structure. On the inner wall of the bottom end of the slot 104, a positioning block 105 is fixedly connected. During the operation of the device, the material impacts the liner base 2, causing the liner base 2 to receive a force and a horizontal oblique force in the direction towards the mounting component 1. The cooperation between the fixing base 102 and the connecting slot 206 can ensure the connection strength between the mounting base 101 and the movable base 201. The positioning block 105 is arranged in a cylindrical structure. On one side of the fixing base 102, two positioning holes 106 are opened. The two positioning holes 106 are symmetrically distributed. Specifically, the positioning holes 106 extend into the slot 104. On both sides of the mounting base 101, two extension blocks 107 are fixedly connected. The two extension blocks 107 are symmetrically distributed. Through holes 108 are opened through the upper surface of the mounting base 101. The through holes 108 are arranged in a strip structure. The two through holes 108 are symmetrically distributed. At the top end of the through holes 108, grooves 109 are opened. On the lower surface of the mounting base 101, a fitting surface 110 is provided. The fitting surface 110 is arranged in an arc structure. The curvature of the fitting surface 110 is adapted to the curvature of the inner cylinder 5 of the semi-autogenous mill.

[0040] The liner base 2 includes two movable bases 201. The movable bases 201 are located above the mounting base 101. The lengths of the two movable bases 201 are different. On the upper surface of the movable base 201, a material pushing plane 202 is provided. In the middle of the material pushing plane 202, a material pushing groove 203 is opened. The material pushing groove 203 is arranged in an inverted isosceles trapezoid structure. Inside the material pushing groove 203, a plurality of reinforcing ribs 204 are fixedly connected. The plurality of reinforcing ribs 204 are equally spaced. Through holes 205 are opened through the middle of the reinforcing ribs 204. At one end of the lower surface of the movable base 201, a connecting slot 206 is opened. The connecting slot 206 is adapted to the mounting base 101. On the inner wall of the top end of the connecting slot 206, a square slot 207 is opened. The square slot 207 is adapted to the fixing base 102.

[0041] More specifically, a second inclined surface 208 is provided on one side of the inner wall at the top of the square groove 207. The second inclined surface 208 is adapted to the first inclined surface 103. Auxiliary positioning grooves 209 are formed at one end on both sides of the connecting groove 206. The auxiliary positioning grooves 209 are adapted to the extension blocks 107. A screw hole 210 is formed through the inner wall on one side of the square groove 207. The screw hole 210 corresponds to the positioning hole 106. An inner hexagon bolt 211 is movably connected to the inside of the screw hole 210 by a thread. And, one end of the inner hexagon bolt 211 is inserted and connected to the positioning hole 106. A circular groove 212 is formed at one end of the screw hole 210. The other end of the inner hexagon bolt 211 is located in the circular groove 212. Since the inner hexagon bolt 211 is located in the circular groove 212, it will not be impacted by the material and thus will not be deformed. A connecting sleeve 213 is fixedly connected to the middle of the inner wall at the top of the square groove 207. The connecting sleeve 213 is inserted and connected to the insertion slot 104. The connecting sleeve 213 is adapted to the positioning block 105. The lower surface of the movable seat 201 is provided with an arc surface 214. The curvature of the arc surface 214 is adapted to the curvature of the inner cylinder 5 of the semi-autogenous mill.

[0042] Among them, the forward force-bearing surface 3 includes a first force-bearing surface 301, a second force-bearing surface 302 and a third force-bearing surface 303. The first force-bearing surface 301, the second force-bearing surface 302 and the third force-bearing surface 303 are all located on one side of the movable seat 201. The forward force-bearing surface 3 pushes the material during rotation, thereby realizing the lifting of the material. The first force-bearing surface 301 can directly push the material. The second force-bearing surface 302 and the third force-bearing surface 303 can respectively push the material through the first crushing block 305 and the second crushing block 306, so that the material can be pushed to a high place.

[0043] Specifically, the first force-bearing surface 301, the second force-bearing surface 302 and the third force-bearing surface 303 are distributed in sequence from top to bottom. The second force-bearing surface 302 and the third force-bearing surface 303 are arranged in a stepped structure. The inclination angles of the first force-bearing surface 301, the second force-bearing surface 302 and the third force-bearing surface 303 increase in sequence. The inclination angles of the first force-bearing surface 301, the second force-bearing surface 302 and the third force-bearing surface 303 are 60°, 70°, 80° respectively. The inclination angles of the first force-bearing surface 301, the second force-bearing surface 302 and the third force-bearing surface 303 can be adaptively adjusted according to the processing accuracy of the semi-autogenous mill for the material. More specifically, since the force-bearing area of the first force-bearing surface 301 is relatively large, the material pushing work mainly depends on the first force-bearing surface 301. And the inclination angle of the first force-bearing surface 301 is relatively small. Therefore, the material will only slide down when it follows the first force-bearing surface 301 to a position close to the top of the inner cylinder 5 of the semi-autogenous mill, and the falling route of the material is relatively steep. When the material slides onto the second force-bearing surface 302 and the third force-bearing surface 303, the first crushing block 305 and the second crushing block 306 cooperate to realize the crushing treatment of the material. The device can perform the crushing treatment on large pieces of material in this state.

[0044] Moreover, a first splicing inclined surface 304 is provided at the bottom end of the third stress-bearing surface 303, and a plurality of first crushing blocks 305 are fixedly connected to the upper surface of the second stress-bearing surface 302. The first crushing blocks 305 are arranged in a right trapezoidal structure, and the plurality of first crushing blocks 305 are equally spaced. A plurality of second crushing blocks 306 are fixedly connected to the upper surface of the third stress-bearing surface 303, and the top end of the outer side surface of the second crushing blocks 306 is arranged in an inclined structure, and the plurality of second crushing blocks 306 are equally spaced.

[0045] The reverse stress-bearing surface 4 includes a first inclined surface 401, a second inclined surface 402 and a second splicing inclined surface 403. The first inclined surface 401, the second inclined surface 402 and the second splicing inclined surface 403 are all located on the other side of the movable seat 201. The reverse stress-bearing surface 4 pushes the material during the movement, so that the material is pushed to a high place. At this time, the first inclined surface 401 and the second inclined surface 402 realize the material pushing work. Since the stress-bearing area of the first inclined surface 401 is large, the pushing work mainly depends on the first inclined surface 401. And the inclination angle of the first inclined surface 401 is large, so the material will slide down when it follows the first inclined surface 401 to a position near the upper middle part of the inner cylinder 5 of the semi-autogenous mill. Specifically, the falling line of the material is relatively gentle, so the material will fall on the first inclined surface 401 and the second inclined surface 402. Since both the first inclined surface 401 and the second inclined surface 402 are arranged as flat surfaces, the material will be crushed under the action of impact. The device can crush small pieces of material in this state. The first inclined surface 401, the second inclined surface 402 and the second splicing inclined surface 403 are distributed in sequence from top to bottom, and the inclination angle of the first inclined surface 401 is greater than that of the second inclined surface 402.

[0046] More specifically, the inclination angles of the first inclined surface 401 and the second inclined surface 402 are 70° and 50° respectively. The inclination angles of the first inclined surface 401 and the second inclined surface 402 can be adaptively adjusted according to the crushing degree of the material by the semi-autogenous mill, but it should be ensured that the inclination angle of the first inclined surface 401 is greater than that of the second inclined surface 402. The second splicing inclined surface 403 is adapted to the first splicing inclined surface 304. The first splicing inclined surface 304 and the second splicing inclined surface 403 cooperate to make the adjacent two lining bases 2 fit tightly, thus ensuring the installation accuracy of the device.

[0047] Embodiment 2

[0048] When installing this device, first install and fix multiple installation components 1 on the inner wall of the semi-autogenous mill inner cylinder 5. During installation, it should be ensured that adjacent two installation components 1 are installed staggeredly, so that the welding solder joints or bolt anchor points are staggered, to ensure the force load of the installation component 1. Then install and fix the liner base 2 above the installation component 1. The liner base 2 consists of two movable seats 201 with different lengths. When installing the liner base 2 above the installation component 1, it should be ensured that the two movable seats 201 above adjacent two installation components 1 are staggered, that is, the longer movable seat 201 should be in contact with the shorter movable seat 201, so as to enhance the strength of the annular structure composed of the installation component 1 and the liner base 2.

[0049] When installing and fixing the installation component 1, the mounting seat 101 can be directly fixed on the inner wall of the semi-autogenous mill inner cylinder 5 by welding, or bolts can be inserted into the mounting holes 108 and cooperate with the pre-reserved screw holes on the inner wall of the semi-autogenous mill inner cylinder 5 to realize the installation and fixing of the mounting seat 101. After installation, the nut part of the bolt is located in the groove 109.

[0050] When installing the liner base 2, place the movable seat 201 above the mounting seat 101 so that the connecting groove 206 corresponds to the mounting seat 101. Push the movable seat 201 so that the movable seat 201 moves towards the mounting seat 101 until the square groove 207 on the connecting groove 206 is clamped with the fixing seat 102 above the mounting seat 101. At this time, the connecting sleeve 213 is inserted and connected with the slot 104, and the positioning block 105 in the slot 104 is inserted into the connecting sleeve 213. Insert the hexagon socket head bolt 211 into the screw hole 210 and rotate the hexagon socket head bolt 211 so that the hexagon socket head bolt 211 slides in the screw hole 210 until the hexagon socket head bolt 211 is inserted into the positioning hole 106. At this time, the position between the connecting sleeve 213 and the slot 104 is fixed, the position between the movable seat 201 and the fixing seat 102 is fixed, and the liner base 2 is installed and fixed above the installation component 1.

[0051] During the operation of the device, the material impacts the liner base 2, causing the liner base 2 to receive a force and a horizontal oblique force in the direction towards the installation component 1. The cooperation of the fixing seat 102 and the connecting groove 206 can ensure the connection strength between the mounting seat 101 and the movable seat 201. At the same time, the cooperation of the connecting sleeve 213, the slot 104 and the positioning block 105 can further enhance the connection strength between the mounting seat 101 and the movable seat 201. And during this process, since the hexagon socket head bolt 211 is located in the circular groove 212, it will not be impacted by the material, so it will not be deformed, thus ensuring the fixing strength.

[0052] Embodiment 3

[0053] When the inner cylinder body 5 of the semi-autogenous mill rotates forward, the liner base 2 rotates forward following the inner cylinder body 5 of the semi-autogenous mill. At this time, the forward force-bearing surface 3 pushes the material during the rotation, thereby realizing the lifting of the material. The first force-bearing surface 301 can directly push the material, and the second force-bearing surface 302 and the third force-bearing surface 303 can push the material through the first crushing block 305 and the second crushing block 306 respectively, so that the material can be pushed to a high place. Since the force-bearing area of the first force-bearing surface 301 is relatively large, the material pushing work mainly relies on the first force-bearing surface 301. And the inclination angle of the first force-bearing surface 301 is small, so the material will slide down when it runs close to the top position of the inner cylinder body 5 of the semi-autogenous mill following the first force-bearing surface 301, and the falling route of the material is relatively steep. When the material slides onto the second force-bearing surface 302 and the third force-bearing surface 303, the first crushing block 305 and the second crushing block 306 cooperate to realize the crushing treatment of the material. The device can carry out the crushing treatment of large-particle materials in this state.

[0054] Example 4

[0055] When the inner cylinder body 5 of the semi-autogenous mill rotates reversely, the liner base 2 rotates reversely following the inner cylinder body of the semi-autogenous mill. The reverse force-bearing surface 4 pushes the material during the movement, so that the material is pushed to a high place. At this time, the first inclined surface 401 and the second inclined surface 402 realize the material pushing work. Since the force-bearing area of the first inclined surface 401 is relatively large, the material pushing work mainly relies on the first inclined surface 401. And the inclination angle of the first inclined surface 401 is large, so the material will slide down when it runs to a position above the middle of the inner cylinder body of the semi-autogenous mill following the first inclined surface 401, and the falling line of the material is relatively gentle. Therefore, the material will fall onto the first inclined surface 401 and the second inclined surface 402. Since both the first inclined surface 401 and the second inclined surface 402 are set as flat surfaces, the material will be crushed under the action of impact. The device can carry out the crushing treatment of small-particle materials in this state.

[0056] Example 5

[0057] An outer cylinder body 6 is arranged on the outer periphery of the inner cylinder body 5 of the semi-autogenous mill. A sealing ring 7 is arranged on the outer cylinder body 6. The sealing ring 7 is connected with the inner cylinder body 5 in an extrusion sealing manner. The sealing ring 7 forms a first air supply area 8 and a second air supply area 9 with the inner cylinder body 5 and the outer cylinder body 6.

[0058] Ventilation holes are provided on the inner cylinder 5, and a first channel 215 is provided in the movable seat 201, and the first channel 215 is respectively connected with the blowing holes 307 on the first force-bearing surface 301 and the second force-bearing surface 302; a second channel 216 is provided in the movable seat 201, and the second channel 216 is connected with the blowing holes 307 on the second inclined surface 402; when the liner base 2 installs the movable seat 201 on the inner wall of the inner cylinder 5 through the mounting assembly 1, the first channel 215 on the movable seat 201 is connected with the ventilation holes on the inner cylinder 5, and the second channel 216 on the movable seat 201 is connected with the ventilation holes on the inner cylinder 5.

[0059] like Figure 10 As shown, the first air supply area 8 is arranged at the upper left side of the inner cylinder 5, which is the position where large-particle materials slide down. When the inner cylinder 5 of the semi-autogenous mill rotates forward to crush large-particle materials, high-pressure blowing air is supplied to the first air supply area 8. The high-pressure blowing air can enter the first channel 215 and the second channel 216 through the ventilation holes on the inner cylinder 5 at the first air supply area 8, and then blow out from the first force-bearing surface 301, the second force-bearing surface 302 and the blowing holes 307 on the second inclined surface 402. Since the first air supply area 8 is located at the position where the large particle materials slide down, the blown high-pressure wind has at least the following effects: on the one hand, it can impact the large particle materials that slide down, play a crushing role, and improve the crushing effect of the large particle materials; on the other hand, the impact on the large particle materials that slide down can make the large particle materials loose, can increase the falling area of ​​the large particle materials after they fall down, and increase the total contact area between the large particle materials and the first force-bearing surface 301, the second force-bearing surface 302, the third force-bearing surface 303 and the second inclined surface 402, thereby improving the large particle crushing effect; furthermore, the impact of the high-pressure wind on the large particle materials that slide down makes the large particle materials loose, which can make the fine particles (including materials that have met the crushing particle size) mixed in the large particle materials The particles are lifted up and discharged and collected through the exhaust system, so that the materials that meet the crushing size can be discharged and collected in time to prevent the materials that meet the crushing size from being over-crushed. After the fine particles that meet the crushing size are separated in time, it is conducive to the continued crushing of large particles that do not meet the crushing size. In particular, the impact of high-pressure wind on the sliding large particles can accelerate the large particles to move downward. Compared with falling only by gravity, the large particles can move downward at a higher speed and impact the first force-bearing surface 301, the second force-bearing surface 302, the third force-bearing surface 303 and the second inclined surface 402 below, thereby greatly improving the crushing effect of the large particles and improving the crushing efficiency of the large particles. The effect is particularly significant.

[0060] like Figure 11As shown, the second air supply area 9 is arranged at the middle position on the right side of the inner cylinder 5, which is the position where the small particle material slides down halfway. After the large particle material is broken into small particle materials, the inner cylinder 5 of the semi-autogenous mill rotates in the reverse direction to crush the small particle materials. At this time, high-pressure blowing is supplied into the second air supply area 9. The high-pressure blowing can enter the first channel 215 and the second channel 216 through the ventilation holes on the inner cylinder 5 passing through the second air supply area 9, and then blow out from the blowing holes 307 on the first stress surface 301, the second stress surface 302 and the second inclined surface 402. Since the second air supply area 9 is located at the position where the small particle material slides down halfway, when the small particle material falls from the sliding position to the halfway position, the small particle material that has fallen and dispersed preliminarily, under the action of the blown high-pressure air, on the one hand, can further disperse the falling small particle material, increase the dispersed area, and further increase the area falling onto the first stress surface 301, the second stress surface 302, the third stress surface 303 and the second inclined surface 402, increasing the effective area for the small particle material to be further broken, and thus improving the crushing effect; on the other hand, under the action of the high-pressure blowing, the materials in the further dispersed small particle materials that meet the crushing particle size are lifted up and can be discharged and collected by the exhaust system. Thus, the materials in the small particle materials that meet the crushing particle size are separated and collected. This can not only prevent the small particle materials that meet the crushing particle size from being over-crushed, but also improve the crushing effect of the remaining small particle materials after the materials that meet the crushing particle size are separated in time, thereby improving the crushing efficiency of the small particle materials, and the effect is particularly remarkable.
