Then, in the late 1980s when the price of copper rose quickly from a low of /lb to a high of /lb, this substantial increase in price further fuelled the industry demand for larger diameter SAG mills, with mill power quickly doubling from 15,000hp to 30,000hp (11,00022,000kW). As SAG mills grew in size and number, so did the size and ...

Rod mills generate small amounts of fines, as fine particles typically accumulate in the space between rods without enduring comminution [2]. Effective grinding of this material occurs in the ball mill compartment, generating finer fragmentation.

Rod mills are similar in shape and size to ball mills but differ in the way they are used to grind material. In a rod mill, the grinding medium is a steel rod rather than a ball. The material to be ground is added to the mill, and as the cylinder rotates, the rods cascade and grind the material.

Overcharging results in poor grinding and losses due to abrasion of rods and liners. Undercharging also promotes more abrasion of the rods. The height (or depth) of charge is measured in the same manner as for ball mill. The size of feed particles to a rod mill is coarser than for a ball mill. The usual feed size ranges from 6 to 25 mm.
