Description

Technical Field

[0001] The utility model relates to the technical field of ball mill lining plates, in particular to a damping type lining plate for an ultrafine ball mill. Background Art

[0002] Ultrafine ball mill is a kind of high-efficiency grinding equipment, which is widely used in mineral processing, building materials, chemical industry and other industries to perform ultrafine grinding of materials. It drives the main shaft and turbine to rotate at high speed through the motor, and the grinding media (such as steel balls) in the mill use the energy obtained when the mill rotates to perform impact crushing and grinding. Compared with traditional ball mills, ultrafine ball mills have the advantages of high crushing efficiency, low energy consumption and strong processing capacity.

[0003] Ball mills are commonly used crushing equipment in industrial production. One of their core components is the liner. The liner not only protects the cylinder from direct impact and friction of the grinding body, but also has a significant impact on the height of the grinding body and the crushing effect of the material. The material, shape and design parameters of the liner will have a significant impact on the grinding efficiency of the ball mill. The damping liner is a liner designed using damping technology. It is mainly used to reduce vibration and noise, and improve the performance and life of the equipment. Damping technology absorbs vibration energy and reduces the transmission of vibration to the structure, thereby reducing the impact of vibration on the equipment and structure.

[0004] Regarding the existing related technologies, the inventors believe that the following defects exist: after the ball mill has been working for a long time, the liner will be worn and need to be replaced, but the liner in the existing technology is fixed to the inner wall of the cylinder of the ball mill by bolts, and the staff needs to remove the bolts one by one before removing the corresponding liner, which is a cumbersome operation. Utility Model Content

[0007] Among them, the other end of the first damping type lining is fixedly connected to the first connecting block, one end of the first connecting block is fixedly connected to the first limiting block, the first connecting block and the first limiting block are movably connected to one end of the fixed bar, the other end of the second damping type lining is fixedly connected to the second connecting block, one end of the second connecting block is fixedly connected to the second limiting block, and the second connecting block and the second limiting block are movably connected to the other end of the fixed bar.

[0008] Preferably, the first connecting block is movably connected to the inside of the movable groove, and the first limiting block is movably connected to the inside of the limiting groove.

[0009] Preferably, the second connecting block is movably connected to the inside of the movable groove, and the second limiting block is movably connected to the inside of the limiting groove.
