The working principle of ball mill

22-05-2019· 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.

Variables in Ball Mill Operation

In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time. For most companies the production mill already exists so we can ignore mill diameter and focus on the other variables.
