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.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Ball mills are giant drums that are filled to between 30 and 40% of their volume with freely moving milling media — in this case, balls. The diameter of the balls is between one and several centimeters to suit the application — smaller balls for fine milling results and larger ones for coarser milling tasks. The drive sets the milling drum ...
