Working principle of ore ultra fine grinding mill

The ultra fine grinding mill is composed of a main shaft, a dispersing disc, a reflecting cage and a bushing. During operation, the mechanical energy generated by the rotation of the dispersing disc is transmitted to the grinding medium through the rotation of the main shaft, so that the material is ground and dispersed uniformly. A reflective cage is arranged at the front end of the main shaft to prevent the grinding medium from collecting at the discharge scree and causing wear on the screen.
