Ball Mill
The correct sizes are often determined by trial and error, primary grinding usually requiring a graded charge of 10-5 cm diameter balls, and secondary grinding requiring 5-2 cm. Concha et al. (1988) have developed a method to calculate ball mill charge by using a grinding circuit simulator with a model of ball wear in a tumbling mill.
Wet and dry grinding of coal in a laboratory-scale ball mill: Particle
The mode of grinding, wet or dry, has significant differences in grinding kinetics and the properties of the ground products. Breakage rates (first-order hypothesis) for wet grinding are faster than those for dry grinding when the solid concentration is less than 50 vol %. This is attributable to the interactions between the broken surface ...
