Ball mill - Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Unlike ball milling where the whole vessel rotates or oscillate/vibrates whilst in operation, the vessel remains stationary in media milling. Movement of the balls is initiated by a stirring or agitating device, often represented by several discs mounted on a central shaft rotating at high velocities, 20 000 rpm and above, within the vessel.

Autogenous Grinding Information - Mine Engineer

Autogenous Mills operate, mechanically, similar to the ball mill. They differ in the media they use to break or grind the ore. Autogenous Mills use large particles of ore instead of steel or other balls for grinding media. Autogenous mills use large pieces of ore as grinding media. The grinding is facilitated in autogenous mills by attrition ...
