Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a ball mill liner installation structure. Background Art

[0002] Ball mill is a kind of equipment widely used in ceramics, cement, silicate products, new building materials, refractory materials, fertilizers, non-ferrous metal beneficiation, glass and other production industries to grind various ores and other grindable materials.

[0003] The ball mill is usually composed of a driving motor, a transmission gear set, a revolving main shaft and a turntable, and a cylinder that rotates around the axis. When the ball mill is working, firstly, many rigid balls are placed in the cylinder. When the cylinder rotates around the axis, the rigid balls are acted upon by centrifugal force and rely on the friction resistance between them and the cylinder lining to flip to the highest point and then fall freely, thereby crushing the abrasive.

[0004] Generally, the cylinder of a ball mill includes an end plate made of a steel plate. In order to avoid wear of the cylinder by the rigid balls and abrasives, and to avoid contamination of the abrasives due to cylinder wear, a rubber lining is conventionally provided in the ball mill. A plurality of cylinder linings are evenly distributed along the inside of the cylinder, and a plurality of fan-shaped end linings are evenly distributed on the end plate. Each cylinder lining or each end lining is fixed to the cylinder or the end plate by a fixing member.

[0005] Reference Figure 1 There is a ball mill liner installation structure. When laying the liner, the end liner 3 is usually installed first, and then the cylinder liner 2 is installed. In order to strictly protect the cylinder 1, the cylinder liner 2 directly presses the end liner 3. In actual operation, in addition to the overall overhaul, each liner needs to be replaced individually according to the wear condition. This structure results in the need to dismantle the adjacent cylinder liner 2 when replacing the end liner 3, which leads to low replacement efficiency of the end liner 3. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a ball mill liner installation structure, which does not require the removal of the cylinder liner when replacing the end liner, thereby improving the replacement efficiency of the end liner.

[0007] The technical solution of the utility model to solve the above technical problems is as follows:

[0008] A ball mill liner installation structure includes a barrel liner and an end liner, a distance is left between the end of the barrel liner and the end of the end liner, a sealing strip is provided between the end of the barrel liner and the end of the end liner, and a step is provided on the side of the end of the end liner facing the barrel liner, and the step is located below the barrel liner.

[0009] By adopting the above technical solution, when the end liner needs to be replaced, it is only necessary to directly remove the fixings of the end liner to be removed, move the end liner toward the cylinder liner along the axial direction of the cylinder, make the step at the end of the end liner close to the cylinder liner, and remove the end liner. There is no need to remove the cylinder liner, which greatly improves the replacement efficiency of the end liner.

[0010] Furthermore, a platform is provided on one side of the end of the cylinder liner toward the inside of the cylinder, and the platform is arranged away from the end liner.

[0011] By adopting the above technical solution, the distance between the end liner and the cylinder liner can be further increased, thereby further reducing the impact of the cylinder liner on the disassembly of the end liner, facilitating the replacement of the end liner, and improving the replacement efficiency of the end liner.

[0012] Furthermore, the end of the end lining plate is not higher than the upper end surface of the platform.

[0013] By adopting the above technical solution, during the process of moving the end liner toward the cylinder liner, the upper end surface of the platform will not affect the movement of the end liner, so that the movement range of the end liner is larger, which is more conducive to rapid replacement of the end liner.

[0014] Furthermore, the end of the end lining plate is flush with the upper end surface of the platform.

[0015] By adopting the above technical solution, the length of the end liner can be retained as much as possible without affecting the movement of the end liner by the upper end surface of the platform, thereby ensuring the strength of the end liner.

[0016] Furthermore, the sealing strip is a rubber strip.

[0017] By adopting the above technical solution, the sealing strip is made of highly elastic polymer rubber with reversible deformation, which can well seal the ends of the cylinder liner and the end liner, greatly improving the sealing performance of the sealing strip, thereby ensuring the normal operation of the equipment.

[0018] Furthermore, the sealing strip is detachably abutted between the end of the cylinder liner and the end of the end liner.

[0019] By adopting the above technical solution, the sealing strip can be installed again after being disassembled, thereby improving the utilization rate of the sealing strip.

[0020] Furthermore, the sealing strip plug is arranged between the end of the cylinder lining plate and the end of the end lining plate.

[0021] By adopting the above technical solution, the sealing strip can be easily disassembled and installed, and the utilization rate of the sealing strip can be improved.

[0022] In summary, compared with the prior art, the above technical solution has the following beneficial effects:

[0023] (1) By providing the sealing strip and the step, when the end liner needs to be replaced, it is only necessary to directly remove the fixings of the end liner to be removed, move the end liner toward the cylinder liner along the cylinder axis, make the step at the end of the end liner close to the cylinder liner, and then remove the end liner without removing the cylinder liner, which greatly improves the replacement efficiency of the end liner;

[0024] (2) By setting up a platform, the distance between the end liner and the shell liner can be further increased, thereby further reducing the impact of the shell liner on the removal of the end liner, making it easier to replace the end liner and improving the replacement efficiency of the end liner;

[0025] (3) By setting the end of the end liner not higher than the upper end surface of the platform, the upper end surface of the platform will not affect the movement of the end liner during the process of moving the end liner toward the cylinder liner, so that the movement range of the end liner is larger, which is more conducive to rapid replacement of the end liner.
