The ball mill is suitable for grinding various ores and other materials, is widely used in the industries of mineral separation, building materials, chemical industry and the like, and can be divided into a dry type ore grinding mode and a wet type ore grinding mode. According to different ore discharge modes, the method can be divided into a lattice type and an overflow type.
At present, the ceramic is found to be a good wear-resistant material through research, and if the ceramic is applied to a lining plate of a ball mill, the abrasion to the lining plate of the ball mill during ball milling operation can be effectively prevented, and the wear resistance and the impact resistance of the contact surface of the lining plate of the ball mill and a ball milling material are improved. The existing ball mill lining plate is large in abrasion during ball milling operation, needs to be frequently disassembled, replaced or maintained, and is low in working efficiency when shut down maintenance or assembly or replacement is caused, so that the efficiency of ball milling materials is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the abrasion speed is high when the existing ball mill lining plate ball milling operation exists in the prior art, and providing a high-strength wear-resistant ball mill lining plate.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
designing a high-strength wear-resistant ball mill lining plate, which comprises a plurality of protective shells and a plurality of lining plates, the inner lining plate is fixedly connected on the inner wall of the protective shell, the protective shells are detachably connected through a fastening structure, a buffer structure is arranged between the protective shell and the lining plate, the buffer structure comprises an elastic cushion, a U-shaped plate, a bolt, a buffer spring and an internal thread pipe, the inner lining plate is provided with a first through hole, the U-shaped plate is provided with a second through hole, the bolt is inserted in the first through hole and the second through hole, a groove is arranged on the inner wall of the protective shell, the internal thread pipe is vertically and fixedly connected in the groove, the end part of the bolt is screwed in the internal thread pipe, the elastic soft gasket is lined between the lining plate and the U-shaped plate, the buffer spring is sleeved on the bolt between the U-shaped plate and the internal thread pipe.
Preferably, the fastening structure includes clamp and layering, the layering rigid coupling is in on the protective housing both sides, the clamp joint is adjacent two on the protective housing on the layering.
Preferably, the buffer spring is always in a compressed state.
The utility model provides a pair of wear-resisting type ball mill welt of high strength, beneficial effect lies in: this wear-resisting type ball mill welt of high strength can be cushioned partly by buffer structure at the impact force of the inside spheroid of ball mill during operation to the production of inside lining board, cushions the protection to the inside lining board, prevents that the inside bushing plate from damaging fast.
