Ball Mill; Principle, Working, and Construction » Pharmaguddu
Low speed: At low speed, the mass of balls will slide or roll up one over another and will not produce a significant amount of size reduction. High Speed: At high-speed balls are thrown to the cylinder wall due to centrifugal force and no grinding will occur. Normal speed: At Normal speed balls are carried almost to the top of the mill and …

The working principle of ball mill
The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact ...
