How does a ball mill work? The working principle is simple: firstly, you should put the material into the cylindrical shell from the feeding part. When the barrel rotates, the steel ball in the cylindrical under the influence of friction and centrifugal force, it will be raised to a certain height, then the ball impacts the material when it drops.

Ball Mill Working Principle. Grinding is usually performed wet, although in certain applications dry grinding is used. When the mill is rotated, the mixture of medium, ore, and water, known as the mill charge, is intimately mixed; the medium comminuting the particles depends on the speed of rotation of the mill and the shell liner structure.
