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.

WORKING: The material to be grind is fed at angle of 60 degree into the crushing zone and the product is discharged at 30 degree. As the shell rotates the balls are lifted up on the rising side of the shell and they cascade down from near the top of the shell. The solid particles in between balls are ground and reduced in size by impact.
