Analysis and validation of a run-of-mine ore grinding mill circuit model for process control

cessing industry are ball and semi-autogenous (SAG) mills, which use both ore and steel balls as grinding media (Wei and Craig, 2009b). In the case of a ball mill the ore is crushed before it enters the mill, whereas a SAG mill re-ceives run-of-mine (ROM) ore

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.
