WhatsApp: +86 18838072829Ball mills classify materials by using a combination of impact and attrition forces to reduce the size of particles. The classification is achieved by adjusting the speed of the ball mill, the diameter of the ball, and the rate at which the material is fed into the mill. The speed of the ball mill affects the centrifugal force generated by the ...
