One of the most used tumbling mills is the ball mill. This paper reviews different types of grinding media that have been developed and improved over the years and their properties.
Critical Speed: Critical speed is the hypothetical speed at which the centrifugal force is equal to the gravitational force, and the grinding media starts sticking to the inner shell of the equipment instead of falling freely.Grinding at or close to critical speed of the mill yields a poorer grinding efficiency. The ball mills are mostly operated at 65 …

This machine uses steel rods as the grinding media instead of balls, which are commonly used in ball mills. The rods grind the ore by tumbling within the mill, similar to the action of a rotating drum. Rod mills can be operated at lower speeds than other types of mills, making them ideal for fine and coarse grinding applications. ...
