Electromagnetic ball mill

Abstract

The invention provides an electromagnetic ball mill. The electromagnetic ball mill comprises a bracket, a driving part, a cylinder body, a cylindrical grinding container and magnetic grinding bodies.The cylinder body is fixed to the bracket. Two arc-shaped electric conductive strips are arranged on the top of the inner sidewall of the cylinder body. The outer side of the cylinder body is providedwith a power connector communicating with the electric conductive strips. One end of the grinding container is inserted into the cylinder body to be rotatably connected with the cylinder body, and the other end of the grinding container is rotatably connected with the bracket. An electromagnet is mounted on the inner sidewall of the grinding container. The peripheral surface of the grinding container is provided with two conductive contacts corresponding to the electromagnetic conductive strips. One end of each conductive contact abuts against the inner sidewall of the cylinder body, and theother end of each conductive contact is electrically connected with the electromagnet. The grinding bodies are placed in the grinding container. The electromagnetic ball mill reduces the requirementsfor the rotating speed and can raise the grinding bodies to the highest point conveniently and improve the grinding effect.

Description

technical field [0001] The invention relates to the field of grinding equipment, in particular to an electromagnetic ball mill. Background technique [0002] The working principle of the ball mill: the grinding body and materials are added into the barrel of the ball mill according to a certain proportion and sealed. The cylinder of the ball mill rotates under the drive of the motor, and the grinding body is attached to the inner wall of the cylinder under the centrifugal force, and rotates together with the cylinder to rise to a certain height, and is thrown down due to the action of gravity, causing the material to be impacted and ground. And was crushed. [0003] Existing ball mills have high requirements on the motor speed. If the speed is too high, the grinding body will always cling to the inner wall of the cylinder and cannot fall down; if the speed is too small, the grinding body will be thrown out due to gravity before it reaches the highest point of the cylinder. ...

Problems solved by technology

[0003] Existing ball mills have high requirements on the motor speed. If the speed is too high, the grinding body will always cling to the inner wall of the cylinder and cannot fall down; if the speed is too small, the grinding body will be thrown out due to gravity before it reaches the highest point of the cylinder. Drop, less impact force, poor grinding effect
