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.

An increase in the diameter of a mill gives greater economy in two ways : In the first place, the balls do more effective work in a large than in a small mill, because, falling from a greater height, they shatter the pieces of ore with greater force ; in the second place, the ratio of the deadweight of the mill to the weight of the ball charge ...

The ratio of active mill shell surface area to ball charge surface area for the 5.0 meter (16½ foot) unit, is roughly half of that for the 2.4 meter (8 foot) unit. However, the actual ratios are so small (1 or 2 percent) that the amount of grinding at the shell is likely of little significance for either size. ... The critical speed, Nc, in ...

ABC closed circuit, Autogenous-Ball-Mill-Crusher. Another similar technique is the ABC open circuit where the crusher product feeds the ball mill rather than the autogenous mill. Crusher product is typical feed to a ball mill using large diameter balls but not much grinding of 20-25 mm ore can be accomplished in an autogenous mill.

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 30-45%). 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 furthermore characterized by significant differences in the sizes of available grinding jars.
