Rod Mills: 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.

Ball and rod mills are grinding mills commonly used in mining, construction, and chemical industries. The difference between the two lies in their design and operation. A ball mill consists of a cylindrical shell rotating horizontally, while a rod mill has a more elongated body rotating horizontally but at a lower speed. The speed at which the ...

Introduction Rod Mill Used as the primary comminution unit in a grinding circuit. Rods are placed parallel along the length of the rod mill. Rods are 150mm shorter than the mill length. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ball mill but significantly coarser.

The ball load was 455 stainless steel balls one inch in diameter, having a total weight of 30 kg. The particle size distribution was observed after 20, 40, 60, 80, 100, 150, 200 and 300 ball mill revolutions. The energy input was calculated from the net torque (corrected for the torque for the empty mill) and the number of revolutions.

Rod mill As there should be very little direct impact in rod mills, thanks to the rolling charge motion, and as rod mills are rarely bigger than 4 meters in diameter, it is possible to use harder, more brittle cast alloys such as cast highchrome metal liners or composite rubber liners with hard cast inserts on the mill shell. However, the rods
