The mill's horizontal rotations enable the High Carbon-High Chrome balls of different sizes bombard the sample as the mill rotates. The material which gets trapped between the balls and the surface disintegrates. This frictional reaction after material entrapment between the balls surface of the mill grinds the sample to required fineness.
