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.

Ball mills rotate around a horizontal axis and are partially filled with material to be milled plus the grinding medium. The grinding medium can be ceramic balls, pebbles or stainless steel balls. As the ball mill rotates an internal cascading effect is created which reduces the material to a fine powder.
