There are also few variations to the a ball mill, such as a SAG or pebble mill. A roll mill is two opposing rotating hard-faced rollers, one mounted stationary and the other under heavy spring tension. The material to be ground is fed between the rollers and is nipped crushed by pressure tension, versus the crushing abrasion of the ball/rod mills.

2 parallel SAG Mills each feeding 2 parallel Ball Mills (4 total). Around 50,000 TPD total grinding circuit capacity.

Ball mill and rod mill are suitable for different materials. 1. Selection by material's hardness. Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2.

The Sag mill uses lifting plates along the interior of the drum, which lift material throughout the rotations, causing them to fall onto one another to promote crushing. A ball mill has many steel or porcelain balls put in a drum to grind the feed between balls and between the balls and drum inner wall as the drum rotates.
