Ball mill Wikipedia
A ball mill is a type of grinder used to grind and 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. A ball mill consists of a hollow

Monitoring grinding parameters by signal measurements for an

Grinding Mills Mining Technology InfoMine
Rod Mills: Mills loaded with rods as the grinding media are used for primary grinding of rocks and minerals. The rods fall from a height and roll down the mill so the rods impart an impact force as well as an abrasive action. The product size from a rod mill is much coarser. Hence a rod mill generally precedes a ball mill in a
