There are three ways for grinding media to pulverize materials: 1. Rolling: the grinding media rolls in the grinding chamber and pulverizes the material by self-weight. 2. Impact: with the rotation of the ball mill cylinder, grinding media falls from the high place in the grinding chamber and strikes the material. 3.

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners.

What is a Ball Mill? A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
