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.

This is the reason that the size of the electric motor for a primary crusher, that has a production rate of five hundred tons per hour, is so much smaller than the horse power of a rod mill that can only grind three hundred tons per hour. In the harder ore there are less of these fracture lines created with each size reduction.
