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.

2017-1-2 The motion of balls deep within the charge of a rotary grinding mill was investigated. Novel investigative techniques were used to track the motion of the balls, including X-ray filming at 50 frames per second of both the front and side views of a transparent mill, and gamma-camera filming of a radioactive ball. Analysis of the trajectories of the

2004-10-13 of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.
