162012· The grinding performance is strongly affected by the size of grinding media (Stehr, 1988, Mankosa et al., 1989, Kwade et al., 1996, Bel Fadhel and Frances, 2001). Mankosa et al. (1989) investigated the effect of medium size on coal grinding in a vertical stirred mill.
Abstract. One of the most energyintensive processes for producing submicron range calcite is stirred media mill. In the present work, numerous operating parameters such as solid mass fraction, grinding media size, media filling ratio, and grinding time have been investigated using a vertical type stirred media mill.

One of the most efficient devices for micronizing coal is a stirred ball mill. Using the laboratory mill with a relatively high media loading (80 % filling), small grinding media (less than 1 mm diameter), and three coals, effects of some parameters such as media size, stirring speed, and pulp density on the grinding of coals have been studied.
The effect of grinding media performance on milling and operational behaviour was demonstrated under different selected conditions of calcium carbonate slurry milling. A variety of grinding media materials and bead sizes, along with two different stirrer tip speeds, were used in the grinding process to generate a particle size
