Description

Technical Field

[0001] This invention relates to the field of ball mill technology, specifically to a mining ball mill with a wear-resistant rubber liner. Background Technology

[0002] In the production process of a mineral processing plant, ore needs to undergo crushing, grinding, and beneficiation processes to obtain the final product – concentrate powder. The crushing process typically involves applying mechanical forces such as impact or pressure to large ore particles, ultimately producing smaller particles. These smaller particles are then ground to a specific particle size based on the ore's crystal size, allowing for single-crystal liberation of the minerals, followed by separation. Therefore, ball mills are an indispensable and crucial piece of equipment in the mineral processing plant's production process.

[0003] Chinese patent CN211099371U discloses a ball mill rubber liner assembly, comprising several ball mill liner assemblies consisting of a flat liner body, lifting bars, and connecting bolts. The lifting bars of each ball mill liner assembly are disposed on the upper part of the flat liner body. Each ball mill liner assembly has its lifting bars and flat liner body formed into a sail-shaped integrated rubber structure. Strip grooves and wear-resistant metal sheets are provided on the lifting surface of the lifting bars. A mounting boss with T-shaped screw holes is provided at the rear of the flat liner body, and a mounting recess with bolt holes is provided at the front of the flat liner body. Its advantages include significantly improving the wear resistance, impact resistance, and cutting resistance of the ball mill liner lifting bars, reducing grinding costs, and also featuring low noise, easy installation, and long service life, effectively reducing grinding costs.

[0004] The above-mentioned technical solution uses fixing bolts to fix the ball mill liner assembly inside the ball mill cylinder. Although fixing bolts can effectively fix the ball mill liner assembly, the ball mill liner assembly needs to be replaced regularly under high-intensity use. Since the existing ball mill liner assembly is fixed by several fixing bolts, it will be necessary to manually enter the cylinder to assemble and fix it each time the liner assembly is replaced. This makes the replacement process cumbersome and wasteful of manpower. At the same time, it will cause the ball mill to be down for a long time, which will greatly affect the work efficiency. Summary of the Invention

[0005] To address the aforementioned issues, a mining ball mill with wear-resistant rubber liners is provided. The combination of an inner liner installation bucket, interlaced inner liner plates, and a quick-change device can effectively save manpower while improving work efficiency.

[0006] To address the problems of existing technologies, this invention provides a mining ball mill with wear-resistant rubber liners, comprising an outer mounting barrel, an inner liner mounting barrel, a rotary drive device, inserting inner liner plates, and a quick-change device.

The bottom of the interlocking base is provided with an interlocking slide rail and a transmission rack. The side of the interlocking base is provided with a threaded connection hole. The interior of the interlocking base is provided with an installation groove. The inner wall of the installation groove is provided with several snap-fit ​​installation holes. The interior of the installation groove is also provided with a synchronous snap-fit ​​mechanism.

[0010] Preferably, the synchronous snap-fit ​​mechanism includes a first adjusting screw installed inside the insert base, a plurality of synchronous connecting blocks are installed on the first adjusting screw, and the synchronous snap-fit ​​mechanism also includes a plurality of insert snap-fit ​​blocks evenly distributed in the snap-fit ​​mounting holes, and a connecting rod is installed between each insert snap-fit ​​block and the synchronous connecting block.

Simultaneously, the quick-change device simplifies the replacement process, reducing the complexity and labor intensity of manual operations, making equipment maintenance more convenient and efficient. These improvements collectively reduce the long-term operating costs of the ball mill. Furthermore, the introduction of the quick-change device in this mining ball mill enables rapid installation and removal of the interlaced inner liners, significantly shortening downtime associated with traditional replacement methods. This improvement not only reduces production interruptions but also increases production efficiency. Attached Figure Description

[0031] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] See Figures 1 to 11As shown, a mining ball mill with wear-resistant rubber liners includes an outer barrel 2, an inner liner barrel 1, a rotary drive device 3, insert inner liner plates 4, and a quick-change device 5. The bottom of the outer barrel 2 is provided with a discharge port, and both ends of the outer barrel 2 are provided with sealing cover plates 21. One end of the sealing cover plate 21 is provided with a feed port. The inner liner barrel 1 is installed inside the outer barrel 2, and a flow gap is provided between the inner liner barrel 1 and the outer barrel 2. Multiple insert inner liner plates 4 are provided and evenly installed on the inner wall of the inner liner barrel 1. Multiple insert inner liner plates 4 are spliced ​​together. The quick-change device 5 is installed on the side of the outer barrel 2. The quick-change device 5 is used to quickly install and remove the insert inner liner plates 4. The rotary drive device 3 is used to drive the inner liner barrel 1 to rotate.

[0033] The outer casing 2 serves as the outer shell of the ball mill. It has a discharge port at the bottom for discharging the ground ore, and sealing plates 21 at both ends. One sealing plate 21 has a feed inlet for adding the ore to be ground into the ball mill. The inner liner mounting barrel 1 is located inside the outer casing 2, maintaining a certain flow gap. It is used to install and support the insert liner plates 4 and serves as the main working area for ball milling. A rotary drive device 3 provides power to rotate the inner liner mounting barrel 1, thereby causing the insert liner plates 4 and the ore to tumble and be ball-milled. The insert liner plates 4 are evenly installed on the inner wall of the inner liner mounting barrel 1, forming a complete ball mill working surface through interlocking. A quick-change device 5 is designed and installed beside the outer casing 2 to enable quick installation and removal of the insert liner plates 4, reducing downtime and manpower consumption.

[0034] The ore is fed into the inlet of the sealing cover plate 21 via a conveying device and enters the inner liner mounting barrel 1. The rotary drive device 3 is activated, driving the inner liner mounting barrel 1 to rotate, which in turn causes the interlacing inner liner plate 4 and the ore to tumble and collide, achieving ball milling and refining of the ore. With prolonged use, the interlacing inner liner plate 4 will gradually lose its original wear resistance due to wear and needs to be replaced regularly to ensure the ball milling effect and efficiency. First, stop the rotation of the inner liner mounting barrel 1, open the sealing cover plate 21 on one side of the outer barrel 2, and clean the ore remaining inside the interlacing inner liner plate 4. Using the quick change device 5, pull out multiple interlacing inner liner plates 4 from the inside of the inner liner mounting barrel 1. Place the damaged interlacing inner liner plate 4 in the treatment area, and prepare new interlacing inner liner plates 4. The new plates are pre-assembled on the quick change device 5 to ensure that they are consistent with the shape of the inner wall of the inner liner mounting barrel 1. Using the quick-change device 5, the newly assembled insert liner plate 4 is directly inserted into the liner installation barrel 1 and secured with snap-fit ​​mechanisms to ensure a firm installation. After replacing the insert liner plate 4, the sealing cover plate 21 is closed, the rotary drive device 3 is restarted, and the ball mill resumes normal operation. The design of the quick-change device 5 significantly shortens the replacement time of the insert liner plate 4, reduces ball mill downtime, and improves work efficiency. It simplifies the replacement steps, reducing the complexity and labor intensity of manual operation. Through quick-change technology, ball mill production can be restored more quickly, reducing production interruptions caused by downtime for replacing the insert liner plate 4. This effectively improves work efficiency.

[0035] See Figures 2 to 4 As shown, the inner lining installation barrel 1 has multiple first interlacing strip rails 11 inside, the first interlacing strip rails 11 are covered with snap-fit ​​holes 12, the inner lining installation barrel 1 has multiple screening holes 13, and the side of the inner lining installation barrel 1 also has multiple positioning holes 14.

[0036] The inner lining mounting barrel 1 has multiple first interlocking strip rails 11 inside. These first interlocking strip rails 11 are evenly distributed along the axial or circumferential direction of the inner lining mounting barrel 1, providing an installation reference and support for the interlocking inner lining plate 4. The first interlocking strip rails 11 are covered with snap-fit ​​holes 12, which are used to engage with corresponding structures on the interlocking inner lining plate 4, such as snaps and protrusions, to achieve quick and stable installation.

[0037] When installing the inner liner plate 4, the operator inserts the liner plate along the guide of the first interlacing strip rail 11 to ensure accurate positioning. Then, the liner plate is quickly fixed by engaging the snaps or protrusions on the liner plate with the snap-fit ​​holes 12 on the first interlacing strip rail 11. This design simplifies the installation process and improves stability and efficiency. The inner liner mounting barrel 1 has multiple screening holes 13 distributed at different locations within the barrel. During ball milling, as the ore continuously tumbles and collides, the ground ore falls through the screening holes 13 into the flow gap between the inner liner mounting barrel 1 and the outer mounting barrel 2. These screening holes 13 perform preliminary screening, helping to discharge the ground ore promptly and preventing over-grinding. This helps maintain stable operation of the ball mill. The side of the inner liner mounting barrel 1 also has multiple positioning holes 14, which are typically used in conjunction with positioning pins on the quick-change device 5 or other auxiliary tools.

[0038] When replacing the insert liner 4, the positioning hole 14 serves to accurately position and assist in installation. Workers can insert the positioning pin from the quick-change device 5 or other specialized tools into the positioning hole 14 to ensure accurate relative positioning between the liner installation bucket 1 and the replacement device. This design improves the precision and efficiency of the replacement process, reducing installation difficulties and the risk of damage caused by positional deviations.

[0039] See Figures 2 to 5 As shown, the interlacing inner lining plate 4 includes an interlacing base 43, the top of which is mounted on the wear-resistant rubber plate 41. The side of the wear-resistant rubber plate 41 is provided with a pressing bevel 42, and both sides of the wear-resistant rubber plate 41 are provided with multiple first assembly ports 421.

[0040] After the first assembly port 421 on the multiple interlacing inner lining plates 4 is assembled, it will correspond one-to-one with the screening hole 13.

[0041] The basic component of the interlacing liner plate 4 is the interlacing base 43, which is responsible for fixing the wear-resistant rubber plate 41 to the first interlacing strip rail 11 of the liner mounting barrel 1. The design of the interlacing base 43 allows it to easily slide and position along the first interlacing strip rail 11, ensuring the accuracy and stability of the installation.

[0042] The wear-resistant rubber plate 41, installed on top of the interlocking base 43, is the main working part of the liner. It comes into direct contact with the ore and grinding media, enduring strong impacts and abrasion. The selection and design of the wear-resistant rubber plate 41 are aimed at improving the wear resistance of the ball mill and extending the service life of the liner. The pressing bevel 42 on the side of the wear-resistant rubber plate 41 is used during installation to press and engage with the adjacent interlocking liner plates 4, achieving a tight connection and stable assembly of the liner plates. During installation, the first assembly openings 421 on multiple interlocking liner plates 4 are assembled together. Through precise design and manufacturing, it can be ensured that the first assembly opening 421 on each liner plate can precisely align with the first assembly opening 421 on the adjacent liner plates, thus achieving a seamless connection.

[0043] See Figures 5 to 7 As shown, the two sides of the interlocking base 43 are provided with multiple second assembly ports 431 that match the first assembly port 421. The bottom of the interlocking base 43 is provided with an interlocking slide rail 432. The bottom of the interlocking base 43 is also provided with a transmission rack 434. The side of the interlocking base 43 is provided with a threaded connection hole 433. The interior of the interlocking base 43 is provided with an installation groove 435. The inner wall of the installation groove 435 is provided with several snap-fit ​​installation holes. The interior of the installation groove 435 is also provided with a synchronous snap-fit ​​mechanism.

[0044] The second mounting port 431 is used to mate with the first mounting port 421 on the wear-resistant rubber plate 41. The design of the through-slide rail 432 allows the through-base 43 to slide easily along the first through-slide strip rail 11, facilitating the installation and adjustment of the inner liner plate. The precise machining and lubrication of the through-slide rail 432 ensures smoothness and accuracy during sliding. The transmission rack 434 meshes with the gear of the drive mechanism, and the movement of the drive mechanism drives the through-base 43 to move along the strip rail, thereby adjusting the position of the through-slide inner liner plate 4. This design improves the convenience and accuracy of adjusting the through-slide inner liner plate 4. The side of the through-base 43 is provided with a threaded connection hole 433 for mate with a fastener. The insert base 43 has an internal mounting groove 435, and the snap-fit ​​mounting holes correspond one-to-one with the snap-fit ​​holes 12 on the first insert strip rail 11. After the insert base 43 is installed in the designated position on the first insert strip rail 11, the operator controls the snap-fit ​​end of the synchronous snap-fit ​​mechanism to snap into the snap-fit ​​mounting holes and snap-fit ​​holes 12 simultaneously, thereby fixing the insert base 43 in place. The design of the insert base 43 effectively improves installation efficiency.

[0045] See Figure 5 As shown, the synchronous snap-fit ​​mechanism includes a first adjusting screw 436 installed inside the insert base 43, and a plurality of synchronous connecting blocks 437 are installed on the first adjusting screw 436. The synchronous snap-fit ​​mechanism also includes a plurality of inserting snap blocks 439 evenly distributed in the snap-fit ​​mounting holes, and a connecting rod 438 is installed between each inserting snap block 439 and the synchronous connecting block 437.

[0046] The first adjusting screw 436 is installed inside the insertion base 43, serving as the main driving component of the synchronous locking mechanism. The synchronous connecting block 437 is installed on the first adjusting screw 436 and moves with the rotation of the screw, transmitting power and coordinating the synchronous actions of the components. Multiple insertion locking blocks 439 are evenly distributed in the locking mounting holes and are the components that actually perform the locking action. The connecting rod 438 connects the insertion locking blocks 439 and the synchronous connecting block 437, ensuring that the insertion locking blocks 439 can move synchronously with the movement of the synchronous connecting block 437.

[0047] The insertion base 43 is placed at the designated position on the first insertion strip rail 11. At this time, the insertion locking block 439 is in a non-engaged state and is not inserted into the locking mounting hole and locking hole 12. After the insertion base 43 is positioned, the operator begins to operate the synchronous locking mechanism. First, by rotating the first adjusting screw 436, the synchronous connecting block 437 mounted on the screw moves along the screw axis. The movement of the synchronous connecting block 437 is transmitted to the insertion locking block 439 through the connecting rod 438. Since the connecting rod 438 is a rigid connection, the insertion locking block 439 moves synchronously with the synchronous connecting block 437. As the insertion locking blocks 439 move, they gradually approach and insert into the locking mounting hole and locking hole 12. Because the insertion locking blocks 439, the locking mounting hole, and the locking hole 12 are designed with a precise fit, the insertion locking blocks 439 can be smoothly and securely locked into place. Once all the interlocking blocks 439 are engaged, the interlocking base 43 is firmly positioned and fixed to the first interlocking strip rail 11, ensuring the stability of the inner liner and the accuracy of installation. The design of the synchronous connecting block 437 and the connecting rod 438 ensures the synchronicity of all the interlocking blocks 439 during the engagement process. This means that regardless of the position of any interlocking block 439 on the interlocking base 43, the engagement action will begin and end simultaneously, thus guaranteeing the coordination and consistency of the entire engagement process. The synchronous engagement mechanism greatly simplifies the installation process of the interlocking base 43 and improves installation efficiency. Workers only need to rotate the first adjusting screw 436 to complete the entire engagement process, eliminating the need for complex positioning and fixing operations.

[0048] See Figure 1 , Figure 3 and Figure 8 As shown, the quick change device 5 includes an adjusting screw slide 51 installed on the side of the outer barrel 2, a synchronous guide sleeve 55 installed on the adjusting screw slide 51, an angle adjusting seat 54 installed on the movable end of the adjusting screw slide 51, a synchronous conveying device 52 installed on the angle adjusting seat 54, and a synchronous pressing plate 53 installed on the synchronous conveying device 52.

[0049] The interlocking inner liner 4 will gradually lose its original wear resistance due to wear and needs to be replaced periodically. First, ensure that the mining ball mill has completely stopped running and the inner liner installation barrel 1 is no longer rotating. Then, open the sealing cover 21 on one side of the outer installation barrel 2 to facilitate internal cleaning and replacement. Clean the residual ore inside the interlocking inner liner 4, ensuring the replacement environment is clean and free of debris to avoid affecting the installation effect of the new inner liner. Operate the adjusting screw slide 51, so that its moving end drives the angle adjusting seat 54, synchronous conveying device 52, and synchronous pressure plate 53 closer to the interlocking inner liner 4. Adjust to the appropriate position so that the synchronous pressure plate 53 can initially form contact with one side of the interlocking inner liner 4. Use the angle adjusting seat 54 to finely adjust the angle of the synchronous conveying device 52 and the synchronous pressure plate 53 to ensure that the docking area of ​​the synchronous pressure plate 53 can accurately dock with the corresponding position of the interlocking inner liner 4. Next, the synchronous pressing plate 53 is fastened to the threaded connection hole 433 on the side of the insert liner plate 4 using fixing bolts. After the synchronous pressing plate 53 and the insert liner plate 4 are fixed, the adjusting screw slide 51 is operated to move the synchronous pressing plate 53 and the connected insert liner plate 4 a certain distance to the outside of the inner liner mounting barrel 1. This step prepares for the initial removal of the insert liner plate 4. After the insert liner plate 4 has moved outward a sufficient distance, the bolt connection between the synchronous pressing plate 53 and the insert liner plate 4 is released, allowing the synchronous pressing plate 53 to return to its active state. Then, the synchronous pressing plate 53 is rotated and adjusted to the side of the synchronous conveying device 52 to make room for the next operation. The adjusting screw slide 51 is operated to move the synchronous conveying device 52 toward the insert liner plate 4 and fit it onto its outside. Ensure that the transmission end of the synchronous conveying device 52 is in close contact with the transmission rack 434 of the insert liner plate 4. The drive end of the synchronous conveyor 52 is activated, and multiple interlaced inner liner plates 4 are synchronously and quickly withdrawn from the inner liner installation barrel 1 via the transmission rack 434. Throughout the process, the synchronous guide sleeve 55 ensures the stable movement of the interlaced inner liner plates 4. After the damaged interlaced inner liner plates 4 are moved to the treatment area, new interlaced inner liner plates 4 are pre-assembled on the synchronous guide sleeve 55 and the synchronous conveyor 52 to ensure that their shape matches the inner wall of the inner liner installation barrel 1. Subsequently, the newly assembled inner liner plates are directly inserted into the inner liner installation barrel 1 using the synchronous conveyor 52. After the synchronous conveyor 52 disengages from the new interlaced inner liner plates 4, the synchronous pressure plate 53 is reset, and it is pushed closer to the new interlaced inner liner plates 4 by adjusting the screw slide 51 to make necessary pushing and adjustment to ensure that the new inner liner plates are installed in place. Afterwards, the snap-fit ​​fixing devices of the interlaced inner liner plates 4 are operated in sequence to ensure that they are firmly installed. After replacing and securing all the inner liner plates 4, close and lock the sealing cover 21 of the outer casing 2, restoring the ball mill to normal operation. At this point, the replacement of the inner liner plates 4 is complete. This device prevents installation personnel from entering the interior of the inner liner installation casing 1, effectively saving manpower and improving work efficiency.

[0050] See Figures 8 to 11 As shown, the synchronous conveying device 52 includes an inner liner limiting ring 521 installed on the angle adjusting seat 54. The inner liner limiting ring 521 is provided with a plurality of second intersecting strip rails 522, and a plurality of synchronous conveying gears 534 are provided on the outer side of the inner liner limiting ring 521.

[0051] The synchronous conveying gear 534 is matched with the transmission rack 434.

[0052] The inner liner limiting ring 521 is also equipped with a synchronous drive device 523 that synchronously drives multiple synchronous conveying gears 534 to rotate. The inner liner limiting ring 521 has a sliding docking shaft 5211 on its side. The sliding docking shaft 5211 is slidably connected to the inner liner limiting ring 521. A push spring is installed between the sliding docking shaft 5211 and the inner liner limiting ring 521. A pressure sensor that senses the pressure of the push spring is also installed on the inner liner limiting ring 521. The sliding docking shaft 5211 is used to cooperate with the positioning hole 14 of the inner liner mounting barrel 1 for positioning and installation.

[0053] The inner lining limiting ring 521 is moved closer to the inner lining mounting barrel 1 by adjusting the lead screw slide 51 until it contacts the side of the inner lining mounting barrel 1. If the sliding docking shaft 5211 successfully aligns with the positioning hole 14 of the inner lining mounting barrel 1, it indicates that the inner lining limiting ring 521 has moved to the correct position corresponding to the inner lining mounting barrel 1. At this time, the push spring maintains a relatively stable pressure state, and the pressure value detected by the pressure sensor is within the preset range. If the sliding docking shaft 5211 fails to align with the positioning hole 14 and instead contacts the side wall of the inner lining mounting barrel 1, the sliding docking shaft 5211 will be squeezed and retract into the inner lining limiting ring 521. At the same time, the push spring is further compressed, and the pressure value detected by the pressure sensor exceeds the preset range, indicating that the inner lining limiting ring 521 and the inner lining mounting barrel 1 have not moved to the appropriate position. When the pressure sensor detects abnormal pressure, the control system will issue a signal prompting the operator to fine-tune the position of the inner lining limiting ring 521 using the angle adjustment seat 54. Through repeated adjustments and tests, the sliding docking shaft 5211 is correctly aligned with the positioning hole 14, the pressure of the push spring returns to normal, and the pressure sensor detects the correct pressure value. After confirming that the inner liner limiting ring 521 is correctly positioned, the synchronous drive device 523 is activated, causing the synchronous conveying gear 534 to start rotating. The synchronous conveying gear 534 meshes tightly with the transmission rack 434 on the inner liner plate 4, driving the inner liner plate to move smoothly along the second interlacing strip rail 522. When the inner liner plate is replaced or installed as needed, the synchronous conveying device 52 can efficiently complete the conveying and installation of the inner liner plate. The synchronous conveying gear 534 is existing technology and will not be described in detail here.

[0054] See Figures 8 to 11As shown, the synchronous pressing plate 53 has a pushing contact surface on one side, and multiple through-holes 532 are provided on the pushing contact surface.

[0055] Before replacing the insert liner plate 4, first move the synchronous pressing plate 53 to the position corresponding to the insert liner plate 4 by adjusting the lead screw slide 51 and angle adjusting seat 54. At this time, the pushing contact surface initially contacts one side of the insert liner plate 4, preparing for the subsequent fixing operation. Use bolts or other fasteners to connect the insert connection hole 532 on the synchronous pressing plate 53 to the threaded connection hole 433 on the insert liner plate 4. By tightening the bolts, a firm fixing relationship is formed between the synchronous pressing plate 53 and the insert liner plate 4, ensuring that the insert liner plate 4 will not move or fall off during subsequent operations. After the fixing connection is completed, continue to operate the adjusting lead screw slide 51 and other devices to move the synchronous pressing plate 53 and the connected insert liner plate 4 a certain distance to the outside of the inner liner installation barrel 1. This step prepares for the initial removal or installation of the insert liner plate 4. Once the insert liner 4 has moved to the appropriate position, the bolt connection between the synchronous pressing plate 53 and the insert liner 4 is released, allowing the synchronous pressing plate 53 to return to its movable state. At this point, the insert liner 4 can be further moved or disassembled using devices such as the synchronous conveying device 52.

[0056] After replacing the new insert liner plate 4, it is installed into the liner installation barrel 1 using the synchronous conveying device 52. Then, the synchronous pressure plate 53 is reset, and it is pushed closer to the new insert liner plate 4 by adjusting the screw slide 51 to make necessary pushing and adjustment to ensure that the new liner plate is installed in place.

[0057] See Figures 8 to 10 As shown, the angle adjustment seat 54 includes a movable mounting seat 541 installed on the movable end of the adjustment screw slide 51. The movable mounting seat 541 is provided with an arc-shaped adjustment rail 542. An arc-shaped adjustment seat 543 is installed on the arc-shaped adjustment rail 542. The side of the arc-shaped adjustment seat 543 is provided with anti-slip teeth 5431. A push-abutment plate 544 is also installed on the movable mounting seat 541. A second adjustment screw 545 is installed between the push-abutment plate 544 and the movable mounting seat 541.

[0058] The side of the push-off contact plate 544 is also provided with an anti-slip layer, and the arc-shaped adjustment seat 543 is fixedly connected to the inner lining limit ring 521.

[0059] First, the movable mounting base 541 and its components, including the arc-shaped adjusting rail 542 and arc-shaped adjusting seat 543, are moved to a position roughly corresponding to the inner lining mounting barrel 1 by adjusting the lead screw slide 51. As needed, the arc-shaped adjusting seat 543 is guided by the arc-shaped adjusting rail 542 to make small-amplitude rotational adjustments. Then, the second adjusting lead screw 545 is rotated to push the pressing contact plate 544 to apply pressure to the arc-shaped adjusting seat 543. The design of the anti-slip teeth 5431 and the anti-slip layer ensures the stability and accuracy of the adjustment. Based on the initial positioning, the position of the synchronous conveying device 52 and the synchronous pressing plate 53 is finely adjusted by repeatedly adjusting the arc-shaped adjusting seat 543. The design of the angle adjusting seat 54 allows the synchronous conveying device 52 and the synchronous pressing plate 53 to be adjusted in position and angle in multiple dimensions, greatly improving the flexibility and accuracy of installation. The design of the anti-slip teeth 5431, the anti-slip layer, and the second adjusting lead screw 545 ensures stability and reliability during the adjustment process and prevents slippage between components. By quickly and accurately adjusting the angle, the efficiency and quality of replacing the lining of a mining ball mill can be significantly improved, while reducing maintenance costs and time.

[0060] See Figures 8 to 9 As shown, the synchronous guide sleeve 55 and the inner lining limiting ring 521 are coaxially arranged, and the synchronous guide sleeve 55 is provided with multiple third intersecting strip rails 551 inside.

[0061] The bottom of the synchronous guide sleeve 55 is provided with a fixed mounting base 552, and the synchronous guide sleeve 55 is rotatably connected to the fixed mounting base 552. The fixed mounting base 552 is connected to the adjusting screw slide table 51. The synchronous guide sleeve 55 and the inner liner limiting ring 521 are coaxially arranged, which means that their central axes coincide, ensuring their high consistency in spatial position. This design is beneficial for achieving precise guidance and positioning of the insert liner plate 4 during installation. The interior of the synchronous guide sleeve 55 is filled with third inserting strip rails 551. The third inserting strip rails 551 are distributed along the axial direction of the synchronous guide sleeve 55, forming parallel tracks. The third inserting strip rails 551 provide a clear movement path and positioning point for the insert liner plate 4. During the replacement of the insert liner plate 4, the synchronous guide sleeve 55 guides and positions the inserting slide rail 432 of the insert liner plate 4 through the internal third inserting strip rails 551. Because the synchronous guide sleeve 55 is coaxially arranged with the inner lining limiting ring 521, when the inner lining limiting ring 521 moves with the adjustment mechanism, the operator will also adjust the synchronous guide sleeve 55 to move accordingly. This synchronous movement ensures that the inserting inner lining plate 4 can always be kept in the correct position and angle during installation. The synchronous guide sleeve 55 not only plays a guiding and positioning role, but also provides stable support for the inserting inner lining plate 4. When the inserting inner lining plate 4 is subjected to impact or vibration, the synchronous guide sleeve 55 can reduce its shaking and displacement, ensuring the stability of the inserting inner lining plate 4 during installation.

[0062] Specific working principle:

[0063] The ore is fed into the inlet of the sealing cover plate 21 via a conveying device and enters the inner liner mounting barrel 1. The rotary drive device 3 is activated, driving the inner liner mounting barrel 1 to rotate, which in turn causes the interlacing inner liner plate 4 and the ore to tumble and collide, achieving ball milling and refining of the ore. With prolonged use, the interlacing inner liner plate 4 will gradually lose its original wear resistance due to wear and needs to be replaced regularly to ensure the ball milling effect and efficiency. First, stop the rotation of the inner liner mounting barrel 1, open the sealing cover plate 21 on one side of the outer barrel 2, and clean the ore remaining inside the interlacing inner liner plate 4. Using the quick change device 5, pull out multiple interlacing inner liner plates 4 from the inside of the inner liner mounting barrel 1. Place the damaged interlacing inner liner plate 4 in the treatment area, and prepare new interlacing inner liner plates 4. The new plates are pre-assembled on the quick change device 5 to ensure that they are consistent with the shape of the inner wall of the inner liner mounting barrel 1. Using the quick-change device 5, the newly assembled insert liner plate 4 is directly inserted into the liner installation barrel 1 and secured with snap-fit ​​mechanisms to ensure a firm installation. After replacing the insert liner plate 4, the sealing cover plate 21 is closed, the rotary drive device 3 is restarted, and the ball mill resumes normal operation. The design of the quick-change device 5 significantly shortens the replacement time of the insert liner plate 4, reduces ball mill downtime, and improves work efficiency. It simplifies the replacement steps, reducing the complexity and labor intensity of manual operation. Through quick-change technology, ball mill production can be restored more quickly, reducing production interruptions caused by downtime for replacing the insert liner plate 4. This effectively improves work efficiency.
