4.2.5.1 Rod and Ball Mills Rowland (1972) and Rowland and Kjos (1978) have provided detailed sample calculations for sizing conventional rod or ball mills. They are based on laboratory determinations of the Bond Work Index, which gives an estimate of the energy required for rod mill or ball mill grinding. Efficiency factors are listed that relate to, for example, the proposed

Numerical simulation of charge motion in ball mills — Lifter

01.05.1993This paper focuses on the use of a numerical tool known as the discrete element method (DEM) to study the motion of ball charge in ball mills. DEM is employed to simulate the motion of individual balls. While doing so, the effect of liner design on the grinding performance of the mill is studied. Two important factors, such as the configuration

A Review of Advanced Ball Mill Modelling

One pragmatic solution to this in the case of ball mills is to simplify the problem by not including the ore or powder particles in DEM, only the grinding media in the simulations, calculating the product size distribution and the mill capacity in a post-processing stage using a PBM scheme on the basis of the frequencies and magnitudes of collisions, that, is, the collision energy
