Dry ROD MILL Grinding. No other type of mill is so well adapted to dry grinding materials to -4 or -8 mesh in single pass with the production of a minimum amount of fines. A major factor in dry grinding is the rapid removal of finished material to prevent cushioning of the rods. This is accomplished in the End Peripheral Discharge Rod Mill.

The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.

Rod mills and ball mills are two grinding mills with similar working principle. The biggest difference is that the grinding media of rod mill is steel rod while that of ball mill is steel ball. In addition, the processing capacity of the rod mill is larger than that of the ball mill of the same specification.
