When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed. If the rod mill feed is produced with open circuit crushing, apply a 1.2 inefficiency factor to the power calculated for the rod milling stage only.

Generally all types of mills use mechanical forces and friction in the grinding process. A mill model that mainly uses mechanical forces (crushing) is the bar mill. This machine aims to reduce the material for sand production. The operation of the bar mill is based on a grinding process, it has a cylindrical shape (drum) and works horizontally.
