Different specification steel balls are installed on the scale board in the ball mill, when the barrel body rotates and produces centrifugal force,at this time, the steel ball is carried to some height and falls to make the material grinding and striking. The speed of rotation is the greatest important factor in the operation of the ball mill.
Polyurethane screen plates have longer service life and better loading ability. As the loading ability of polyurethane screen plates is more than 2.5 times that of rubber screen plates, its service life is 8-10 times of metal plates, 3 times of SUS, 3.9 times of natural rubber. It is the most wear-resistant material for screen plates.
