Description

Technical Field

[0001] The present application relates to the technical field of ore processing equipment, and in particular to a ball mill capable of monitoring the degree of wear. Background Art

[0002] ‌Ball mill is a kind of equipment used to crush and grind materials. It is mainly used for dry or wet grinding of various ores and other grindable materials. It is widely used in cement, ore dressing, new building materials, refractory materials, chemicals, glass and ceramics and other production industries.‌ During the ore dressing and grinding operations in the ore dressing plant, usually, in order to protect the barrel wall of the ball mill, a wear-resistant lining is installed on the inner wall of the ball mill to reduce wear. When the wear-resistant lining is worn to a certain extent, the machine must be stopped and the lining must be replaced to prevent damage to the barrel wall of the ball mill.

[0003] Since the wear-resistant lining is installed on the inner wall of the mill drum and the drum is constantly rotating, the thickness of the wear-resistant lining cannot be measured through manual inspections. There are a large amount of ore and other materials in the rotating drum, which cannot be measured by traditional thickness gauges. Therefore, the current common practice is to shut down the machine regularly and replace it based on past usage experience.

[0004] However, this will bring the following problems: due to reliance on experience, a relatively conservative inspection cycle is generally selected, but the wear-resistant lining is often less worn at this time, and due to the long downtime of the ball mill, the maintenance frequency is increased, and high-frequency replacement will lead to reduced production capacity, increased costs, and poor economic benefits; and taking the risk of extending the maintenance cycle may cause part of the wear-resistant lining to be worn through, causing the barrel wall of the ball mill to be worn, which is likely to cause safety hazards, further increase the cost of maintenance, and delay the construction period, bringing greater economic losses. Therefore, a ball mill that can monitor the degree of wear is urgently needed to solve the above technical problems. Summary of the invention

[0005] In order to solve the problem that the wear degree of the wear-resistant lining on the inner wall of a traditional ball mill is difficult to monitor, the present application provides a ball mill capable of monitoring the wear degree.

[0006] The present application provides a ball mill capable of monitoring the degree of wear, which adopts the following technical solution: A ball mill capable of monitoring the degree of wear comprises a base and a ball milling cylinder, a plurality of wear-resistant linings being evenly distributed circumferentially on the inner side wall of the ball milling cylinder, a monitoring component being arranged on the wear-resistant lining, the monitoring component being used to monitor the degree of wear of the wear-resistant lining, the ball milling cylinder comprising a front end cylinder and a rear end cylinder being coaxially and detachably arranged, a connecting component being arranged between the front end cylinder and the rear end cylinder, the connecting component being used to fix the front end cylinder on the rear end cylinder, the rear end cylinder being rotatably arranged on the base, a driving component for driving the rear end cylinder to rotate being arranged on the base, an inspection frame being slidably arranged on the base, the front end cylinder being rotatably arranged on the inspection frame, and a sliding component for driving the inspection frame to slide being arranged on the base.

[0007] By adopting the above technical solution, the connecting piece fixes the front end cylinder on the rear end cylinder, and then the driving assembly drives the rear end cylinder to rotate, and the rear end cylinder drives the front end cylinder to rotate synchronously, so that the wear-resistant lining in the ball mill cylinder crushes and grinds the material. When the monitoring part detects that the wear-resistant lining is seriously worn, the worker promptly releases the fixing effect of the connecting piece on the front end cylinder and the rear end cylinder, and then the sliding piece drives the maintenance frame to slide, so that the maintenance frame drives the front end cylinder to separate from the rear end cylinder, and the maintenance personnel simultaneously repair and replace the wear-resistant lining in the front end cylinder and the rear end cylinder, thereby shortening the time consumed for maintenance.

[0008] Optionally, the monitoring component includes an ore layer plate disposed on the wear-resistant lining, the ore layer plate is radioactive, the ore layer plate is located between the wear-resistant lining and the inner wall of the ball mill, and a buffer plate is disposed between the ore layer plate and the inner wall of the ball mill.

[0009] By adopting the above technical solution, the buffer plate reduces the possibility of the ore layer being crushed by the inner wall of the ball mill and the wear-resistant lining. When the wear-resistant lining is worn through, the material in the ball mill will cause wear to the ore layer, and the worn ore layer fragments will be mixed with the material in the ball mill. Since the ore layer is radioactive, workers use special equipment to detect the radioactivity in the product after ball mill grinding. When the radioactivity detected in the product after ball mill grinding exceeds the design requirements, the workers will stop the machine and carry out maintenance and replace the wear-resistant lining, so as to achieve the effect of accurate replacement of the wear-resistant lining.

[0010] Optionally, the connecting member includes a front tube ring coaxially arranged on the front end tube, and a rear tube ring coaxially arranged on the rear end tube, and a plurality of connecting bolts are circumferentially passed through the rear tube ring along its axis, and the connecting bolts slide through the front tube ring, and a locking nut is threadedly connected to the connecting bolt on the side of the front tube ring facing away from the rear tube ring.

[0011] By adopting the above technical solution, workers fix the front tube ring and the rear tube ring together by connecting bolts and locking nuts, so as to realize the synchronous rotation of the front end tube and the rear end tube. At the same time, the cooperation of the connecting bolts and the locking nuts makes it convenient for workers to quickly disassemble and separate the front end tube and the rear end tube.

[0012] Optionally, the drive assembly includes a ring gear coaxially arranged on the rear end cylinder, a drive gear rotatably arranged on the base and meshing with the ring gear, a drive motor electrically connected to the control system is arranged on the base, a reduction gear box is arranged on the base, the output shaft of the drive motor is coaxially connected to the input end of the reduction gear box, and the drive gear is coaxially connected to the output end of the reduction gear box.

[0013] By adopting the above technical solution, the control system starts the drive motor, the output shaft of the drive motor drives the drive gear to rotate through the reduction box, the drive gear drives the rear end cylinder to rotate through the ring gear, and the rear end cylinder drives the front end cylinder to rotate through the connecting bolt, thereby realizing the synchronous rotation of the front end cylinder and the rear end cylinder.

[0014] Optionally, the sliding member includes a slide rail arranged on the base, the inspection frame slidingly cooperates with the slide rail and slides along the length direction of the slide rail, the inspection frame is provided with a sliding motor electrically connected to the control system, the base is provided with a rack parallel to the length direction of the slide rail, and a sliding gear meshing with the rack is coaxially provided on the output shaft of the sliding motor.

[0015] By adopting the above technical solution, when the maintenance personnel remove the connecting bolts, the control system starts the sliding motor, and the output shaft of the sliding motor drives the sliding gear to rotate. Since the rack is fixed on the base, the reaction force of the sliding gear rotation causes the maintenance frame to slide along the length direction of the slide rail, thereby realizing the maintenance frame driving the front end cylinder and the rear end cylinder to separate, so as to facilitate the maintenance personnel to repair the front end cylinder and the rear end cylinder at the same time, which is conducive to shortening the maintenance time.

[0016] Optionally, the length direction of the slide rail is perpendicular to the axis of the front end tube.

[0017] By adopting the above technical solution, the front end tube can slide in the radial direction of its axis. On the one hand, it will not affect the material connection at the discharge end of the front end tube. On the other hand, after the front end tube and the rear end tube are separated, the space occupied in the axial direction of the front end tube is reduced, which is conducive to reducing the use of factory site resources.

[0018] Optionally, end plate rings are coaxially slidably provided on the front end tube and the rear end tube, a grid tube is coaxially provided on the end plate ring, the wear-resistant lining is clamped on the mesh holes on the grid tube, the grid tube includes a cross bar between two circumferentially adjacent wear-resistant linings along the axial direction of the end plate ring and an arc rod between two adjacent wear-resistant linings along the axial direction of the end plate ring, and the cross bar and the arc rod are both provided with deformation grooves along their length direction.

[0019] By adopting the above technical scheme, when the wear-resistant lining needs to be repaired and replaced, the worker removes the end plate ring and uses tools to connect the mesh tube to the wear-resistant lining and pulls it out of the front end tube or the rear end tube, and then installs the new end plate ring at the end of the front end tube or the rear end tube. At this time, the mesh tube is attached to the inner wall of the front end tube or the rear end tube, and then the worker installs the wear-resistant lining in the mesh holes on the mesh tube. At this time, the buffer plate is attached to the inner wall of the front end tube or the rear end tube, and the ore layer is located between the wear-resistant lining and the buffer plate. Then the worker knocks the deformation groove with a tool to deform and expand the cross bar and the arc bar to both sides, so that the mesh holes on the mesh tube become smaller, so that the wear-resistant lining is fixed in the mesh holes on the mesh tube, and at the same time, the ore layer is pressed against the deformation of the cross bar and the arc bar on all sides, thereby realizing the rapid installation of the wear-resistant lining.

[0020] Optionally, a plurality of guide strips with T-shaped cross-sections are circumferentially arranged on the grid tube, and the length direction of the guide strips is parallel to the axis of the front end tube. The inner side walls of the front end tube and the rear end tube are provided with a plurality of guide grooves for the guide strips to be plugged in, and the guide grooves correspond one-to-one to the guide strips.

[0021] By adopting the above technical solution, during the installation of the grid tube, the guide strip on the grid tube is inserted into the guide groove on the inner wall of the front end tube or the rear end tube, thereby reducing the possibility of the grid tube being deformed and detached from the inner wall of the front end tube or the rear end tube during the rotation of the front end tube or the rear end tube, which is beneficial to maintaining the installation stability of the wear-resistant liner.

[0022] Optionally, a rubber ring tube is coaxially arranged at one end of the grid tube facing away from the end plate ring.

[0023] By adopting the above technical solution, the rubber ring pipe blocks the guide groove by deformation, thereby reducing the possibility of materials entering the guide groove and blocking the guide groove, making the mesh pipe difficult to replace.

[0024] Optionally, proximity switches electrically connected to the control system are provided on the maintenance frame at both ends along its sliding direction, and stop plates are provided on the base at both ends of the slide rail, and the sensing end of the proximity switch points to the stop plate.

[0025] By adopting the above technical solution, when the maintenance frame drives the front end cylinder close to the rear end cylinder and triggers the proximity switch, the proximity switch promptly feeds back the signal to the control system, and the control system promptly stops the sliding motor. At this time, the front end cylinder is coaxial with the rear end cylinder, which helps to reduce the difficulty of manually aligning the front end cylinder and the rear end cylinder.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The connecting piece fixes the front end cylinder on the rear end cylinder, and then the driving assembly drives the rear end cylinder to rotate, and the rear end cylinder drives the front end cylinder to rotate synchronously, so that the wear-resistant lining in the ball mill cylinder crushes and grinds the material. When the monitoring part detects that the wear-resistant lining is seriously worn, the worker promptly releases the fixing effect of the connecting piece on the front end cylinder and the rear end cylinder, and then the sliding piece drives the maintenance frame to slide, so that the maintenance frame drives the front end cylinder to separate from the rear end cylinder. The maintenance personnel repair and replace the wear-resistant lining in the front end cylinder and the rear end cylinder at the same time, so as to shorten the time consumed by maintenance; 2. The buffer plate reduces the possibility of the ore layer being crushed by the inner wall of the ball mill and the wear-resistant lining. When the wear-resistant lining is worn through, the material in the ball mill will wear the ore layer, and the worn ore layer debris will be mixed with the material in the ball mill. Since the ore layer is radioactive, workers use special equipment to detect the radioactivity in the product after ball mill grinding. When the radioactivity in the product after ball mill grinding exceeds the design requirements, the workers will stop the machine for maintenance and replace the wear-resistant lining, so as to achieve the effect of accurate replacement of the wear-resistant lining; 3. When the wear-resistant lining needs to be repaired and replaced, the worker removes the end plate ring and uses tools to connect the mesh tube to the wear-resistant lining and pull it out of the front end tube or the rear end tube, and then installs the new end plate ring at the end of the front end tube or the rear end tube. At this time, the mesh tube is attached to the inner wall of the front end tube or the rear end tube, and then the worker installs the wear-resistant lining in the mesh holes on the mesh tube. At this time, the buffer plate is attached to the inner wall of the front end tube or the rear end tube, and the ore layer is located between the wear-resistant lining and the buffer plate. Then the worker knocks the deformation groove with a tool to deform and expand the cross bar and the arc bar to both sides, making the mesh holes on the mesh tube smaller, so that the wear-resistant lining is fixed in the mesh holes on the mesh tube, and at the same time, the ore layer is pressed against the deformation of the cross bar and the arc bar on all sides, so as to achieve rapid installation of the wear-resistant lining.

The ore layer plate 41 is located between the wear-resistant lining 3 and the inner wall of the ball mill 2. A buffer plate 42 is bonded to one side of the ore layer plate 41 close to the inner wall of the ball mill 2. The buffer plate 42 can be made of rubber material.

[0041] Reference Figure 1 , Figure 4 and Figure 5 An end plate ring 9 is coaxially arranged for sliding movement on the front end tube 21 and the rear end tube 22. The end plate ring 9 is bolted to the front end tube 21 or the rear end tube 22. A grid tube 10 is coaxially welded to the end plate ring 9. A plurality of guide strips 11 with T-shaped cross sections are circumferentially welded on the grid tube 10.

The guide grooves 12 correspond to the guide strips 11 one by one. A rubber ring tube 13 is coaxially bonded to one end of the grid tube 10 which is away from the end plate ring 9. The rubber ring tube 13 can be made of rubber material. The wear-resistant lining plate 3 is stuck on the mesh on the grid tube 10.

[0043] Reference Figure 3 , Figure 4 and Figure 5The grid tube 10 includes a cross bar 101 between two circumferentially adjacent wear-resistant liners 3 along the axial direction of the end plate ring 9 and an arc bar 102 between two circumferentially adjacent wear-resistant liners 3 along the axial direction of the end plate ring 9. The cross bar 101 and the arc bar 102 are welded together. The cross bar 101 and the arc bar 102 are both provided with deformation grooves 103 along their length directions, and the cross section of the deformation groove 103 is V-shaped.

[0044] The worker first inserts the end plate ring 9 and the grid tube 10 into the front end tube 21 or the rear end tube 22 through the guiding effect of the guide strip 11 and the guide groove 12, and then bolts the end plate ring 9 to fix it. After that, the wear-resistant lining 3 together with the ore layer plate 41 and the buffer plate 42 are installed in the mesh of the grid tube 10. After that, the deformation groove 103 on the cross bar 101 and the arc bar 102 is knocked by a tool, so that the deformation groove 103 is deformed and expanded to both sides, so that the wear-resistant lining 3 is embedded in the grid tube 10.

[0045] Reference Figure 1 , Figure 4 and Figure 6 The rear end tube 22 is rotatably connected to the base 1, and a driving assembly 6 for driving the rear end tube 22 to rotate is arranged on the base 1. The driving assembly 6 includes a gear ring 61 coaxially welded to the rear end tube 22, and a driving gear 62 meshing with the gear ring 61 is rotatably connected to the base 1. A driving motor 63 electrically connected to the control system is bolted to the base 1.

[0046] Reference Figure 1 , Figure 4 and Figure 6 A reduction box 64 is bolted to the base 1, the output shaft of the driving motor 63 is coaxially connected to the input end of the reduction box 64, the driving gear 62 is coaxially connected to the output end of the reduction box 64, a maintenance frame 7 is slidably arranged on the base 1, the front end cylinder 21 is rotatably connected to the maintenance frame 7, and a sliding member 8 for driving the maintenance frame 7 to slide is arranged on the base 1.

[0047] Reference Figure 2 , Figure 4 and Figure 6 The sliding member 8 includes a sliding rail 81 welded on the base 1, the length direction of the sliding rail 81 is perpendicular to the axis of the front end tube 21, the maintenance frame 7 slides with the sliding rail 81 and slides along the length direction of the sliding rail 81, and the maintenance frame 7 is bolted with a sliding motor 82 electrically connected to the control system.

[0048] Reference Figure 1 , Figure 2 and Figure 6A rack 83 parallel to the length direction of the slide rail 81 is welded on the base 1, a sliding gear 84 meshing with the rack 83 is coaxially welded on the output shaft of the sliding motor 82, and proximity switches 14 electrically connected to the control system are bolted on both ends of the maintenance frame 7 along its sliding direction, and stop plates 15 are welded on both ends of the base 1 and located on the slide rail 81, and the sensing end of the proximity switch 14 points to the stop plate 15.

[0049] Then the control system starts the sliding motor 82, and the output shaft of the sliding motor 82 drives the sliding gear 84 to rotate. The reaction force of the sliding gear 84 on the rack 83 causes the maintenance frame 7 to drive the front end cylinder 21 close to the rear end cylinder 22 until the proximity switch 14 on the maintenance frame 7 is triggered by the stop plate 15. The proximity switch 14 feeds back the signal to the control system, and the control system stops the sliding motor 82 from working.

[0050] At this time, the front end tube 21 is coaxial with the rear end tube 22, and then the worker fixes the front end tube 21 on the rear end tube 22 through the connecting bolts 53 and the locking nuts 54. After that, the control system starts the drive motor 63. The output shaft of the drive motor 63 drives the drive gear 62 to rotate through the reduction box 64. The drive gear 62 drives the rear end tube 22 to rotate synchronously through the ring gear 61. The rear end tube 22 causes the front end tube 21 to rotate synchronously through the connecting bolts 53.

[0051] The material in the ball mill 2 is continuously ground until the wear-resistant lining plate 3 is worn through and the ore layer plate 41 is worn by the material. The worn debris of the ore layer plate 41 is mixed with the material and discharged from the discharge port of the ball mill 2 to the conveyor belt 18. The control system starts the conveying motor 19, and the conveying motor 19 drives the conveyor belt 18 to rotate through the conveying roller 17, and the material is transported to the monitor 20.

[0052] The monitor 20 detects the radioactivity required by the design, the control system stops the drive motor 63 and the conveying motor 19, the maintenance personnel remove the connecting bolts 53 and start the sliding motor 82, so that the inspection frame 7 drives the front end tube 21 away from the rear end tube 22, and then the maintenance personnel remove the bolts on the end plate ring 9, and then pull out the grid tube 10 through the equipment, and only need to install the new end plate ring 9, grid tube 10 and wear-resistant lining 3 again.

[0053] The implementation principle of a ball mill capable of monitoring the degree of wear in an embodiment of the present application is as follows: a worker first inserts the end plate ring 9 and the grid tube 10 into the front end tube 21 or the rear end tube 22 through the guiding effect of the guide bar 11 and the guide groove 12, and then bolts and fixes the end plate ring 9, and then installs the wear-resistant lining 3 together with the ore layer plate 41 and the buffer plate 42 in the mesh of the grid tube 10, and then uses a tool to knock the deformation groove 103 on the cross bar 101 and the arc bar 102, so that the deformation groove 103 is deformed and expanded to both sides, so that the wear-resistant lining 3 is embedded in the grid tube 10.

[0054] Then the control system starts the sliding motor 82, and the output shaft of the sliding motor 82 drives the sliding gear 84 to rotate. The reaction force of the sliding gear 84 on the rack 83 causes the maintenance frame 7 to drive the front end cylinder 21 close to the rear end cylinder 22 until the proximity switch 14 on the maintenance frame 7 is triggered by the stop plate 15. The proximity switch 14 feeds back the signal to the control system, and the control system stops the sliding motor 82 from working.

[0055] At this time, the front end tube 21 is coaxial with the rear end tube 22, and then the worker fixes the front end tube 21 on the rear end tube 22 through the connecting bolts 53 and the locking nuts 54. After that, the control system starts the drive motor 63. The output shaft of the drive motor 63 drives the drive gear 62 to rotate through the reduction box 64. The drive gear 62 drives the rear end tube 22 to rotate synchronously through the ring gear 61. The rear end tube 22 causes the front end tube 21 to rotate synchronously through the connecting bolts 53.

[0056] The material in the ball mill 2 is continuously ground until the wear-resistant lining plate 3 is worn through and the ore layer plate 41 is worn by the material. The worn debris of the ore layer plate 41 is mixed with the material and discharged from the discharge port of the ball mill 2 to the conveyor belt 18. The control system starts the conveying motor 19, and the conveying motor 19 drives the conveyor belt 18 to rotate through the conveying roller 17, and the material is transported to the monitor 20.

[0057] The monitor 20 detects the radioactivity required by the design, the control system stops the drive motor 63 and the conveying motor 19, the maintenance personnel remove the connecting bolts 53 and start the sliding motor 82, so that the inspection frame 7 drives the front end tube 21 away from the rear end tube 22, and then the maintenance personnel remove the bolts on the end plate ring 9, and then pull out the grid tube 10 through the equipment, and only need to install the new end plate ring 9, grid tube 10 and wear-resistant lining 3 again.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
