and charge. After all, it is the interface between the mill and the grinding charge. Although work on the grinding action in mills was published 100 years ago (White 1905 and Davis 1919), the first publication on the influence of liner design on the charge motion only appeared in 70 years later (McIvor 1983).

An optimising design method was presented for designing continuous grinding circuits to meet the requirements for the particulate product expressed as a combination of the mean value and standard deviation of the particle size. A discrete mathematical model, describing the axial mixing and breakage of particles in the mill and some time delay ...

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for …

The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the spe- cific impact energy of the balls calculated from Discrete Element Method simulation. This relationship was successfully used for the scale-up of a rocking ball mill, and the optimum design and
