Ball mill capable of reducing collision abrasion between grinding body and lining plate

Abstract

The invention relates to the technical field of crushing equipment, and discloses a ball mill capable of reducing collision abrasion between a grinding body and a lining plate. The ball mill comprises a rotary inner cylinder, air guide holes are formed in the rotary inner cylinder at equal intervals, and sliding seats are fixedly mounted on the inner surface of the rotary inner cylinder at equal intervals. Through the arrangement of a rising and falling plate and the air guide holes, when the falling grinding body impacts the rising and falling plate, the rising and falling plate moves towards the outer side, then air on the outer side is exhausted through the air guide holes, energy brought by impact is transferred by exhausting the gas, therefore rigid collision between the grinding body and the rising and falling plate is avoided, abrasion between the grinding body and the rising and falling plate is reduced, then, along with the outward movement of the rising and falling plate, the sliding seats on the two sides of the rising and falling plate protrude, so that the grinding body on the rising and falling plate is limited by the sliding seats on the two sides while being subjected to the centrifugal effect, and the situation that the grinding body relatively slides on the rising and falling plate due to the small centrifugal force when the grinding body does centrifugal movement along with the rotary inner cylinder, and abrasion is caused is avoided.

Description

technical field [0001] The invention relates to the technical field of crushing equipment, in particular to a ball mill for reducing collision wear between grinding bodies and liners. Background technique [0002] Ball mill is a kind of high-fine grinding mechanical equipment, which is suitable for grinding various ores and other materials, and is widely used in mineral processing, building materials and chemical industries. [0003] When some existing ball mills are working, the grinding bodies are loaded into the cylinder body composed of liners according to different diameters and certain proportions, and then the cylinder body is rotated, and finally the materials are transported into the rotating cylinder body. Under the centrifugal action of the cylinder, it rotates with the cylinder. When it rotates to a certain angle, it is thrown down due to its own gravity, and the falling grinding body hits the material in the cylinder, and then completes the material crushing ope...
