Description

Technical Field

[0001] The utility model belongs to the technical field of ball mills, and in particular relates to an inner lining plate of a ball mill with a shock-absorbing function. Background Art

[0002] Ball mills are widely used in mines, cement plants, thermal power plants, chemical and metallurgical industries. They are mechanical equipment for re-crushing materials after coarse crushing. The liner installed on the inner wall of the ball mill drum is used to protect the ball mill drum from direct impact and wear of the grinding body and materials. On the other hand, it is used as a lifting bar to lift the material, to increase the material drop height and the movement state of the grinding body (grinding ball), so as to enhance the grinding effect of the grinding body on the material, improve the grinding efficiency of the ball mill, and reduce the metal consumption of the medium ball.

[0003] The inner wall linings of drums currently on the market generally do not have specific buffering and shock-absorbing functions. Due to the high-frequency impact and wear of steel balls and materials, they are not only easy to break, but also produce high-frequency and harsh noise, causing hearing damage to operators and polluting the surrounding environment. Utility Model Content

[0004] The utility model provides a ball mill lining plate with a shock-absorbing function.

[0005] The utility model is realized through the following technical scheme: it comprises a plurality of lining plate bodies of uniform specifications, and shock-absorbing through holes are respectively provided at the four corners of each lining plate body, and each lining plate body is connected to a shock-absorbing mechanism through the shock-absorbing through holes, and the shock-absorbing through holes of adjacent lining plate bodies are arranged on the same shock-absorbing mechanism, and the shock-absorbing mechanism comprises an upper shock-absorbing rubber pad, a lower shock-absorbing rubber pad, a connecting rod, and a spring, and four connecting holes matched with the connecting rod are respectively arranged on the upper shock-absorbing rubber pad and the lower shock-absorbing rubber pad, and the connecting rod passes through the lining plate body, the upper shock-absorbing rubber pad, the spring, and the lower shock-absorbing rubber pad in sequence from the inside to the outside and is then fixed on the cylinder of the ball mill.

[0006] The beneficial effect of the utility model is that the shock absorbing mechanism and the auxiliary shock absorbing mechanism cooperate with each other to absorb the collision force received by the inner lining plate of the ball mill, which can reduce the impact force and impact force of the material and the grinding body on the inner lining plate of the ball mill, thereby reducing the vibration amplitude, extending the service life, and effectively reducing the generation of noise, thereby achieving the purpose of noise reduction.
