Ball mill for cement production

Abstract

The invention relates to the technical field of grinding equipment, and discloses a ball mill for cement production. The ball mill comprises a cylinder; the two ends of the interior of the cylinder are fixedly connected with a lining assembly; the lining assembly is composed of four lining plates; the lining plates are arranged around the cylinder; the two lining plates are clamped with each other; a water storage cavity is arranged between the cylinder and the lining plates; and grooves are arranged in the lining plates, and movable plates are hinged to the inner walls, located at one ends of the grooves, of the lining plates. The movable plates and limiting bags are arranged in the lining plates, so that the movable plates rotate outwards due to gravity in the ascending stage, the movement path of a grinding ball is changed due to the external force of the movable plates during centrifugal operation, the throwing movement is formed, the grinding ball is effectively made to fully grind materials, and the grinding efficiency of the grinding ball is improved, and meanwhile, the lining plates and the movable plates are connected through the limiting bags, so that an effective supporting and protecting effect is provided for rotation of the movable plates, and the phenomenon that the grinding ball is clamped between the movable plates and the lining plates is avoided.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to a ball mill for cement production. Background technique [0002] The ball mill is a key equipment for fine crushing after the material is broken. It is mainly composed of a horizontal cylinder, a liner for protecting the inner wall of the cylinder, and grinding balls. The centrifugal force, friction force, etc. are attached to the cylinder and are rotated and moved. When it is moved to a certain height, it will be thrown down due to its own gravity. The falling ball will hit and crush the material with impact force, resulting in Crushing and dissociation of materials, with good grinding ability, it is widely used in cement production industry. [0003] However, during the actual use of the ball mill, the balls are easy to follow the cylinder to maintain the centrifugal operation state, so that the balls are more evenly distributed on the inner wall of the cylinder, fo...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing ball mills proposed in the background technology, the present invention provides a ball mill for cement production, which solves the problem that the balls are easy to maintain centrifugal operation, and effectively improves the grinding efficiency of the balls on materials. The advantage of promoting the effective enhancement of its grinding effect solves the technical problems raised in the above-mentioned background technology
