Calculate and Select Ball Mill Ball Size for Optimum Grinding. In Grinding selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do.

Analysis of grinding kinetics in a laboratory ball mill

In addition to the ball mill simulation of various milling equipment such as centrifugal mill stirred mill and planetary mill were also studied. For example Mori et al. studied the correlation between impact energy and grinding rate for a wet ball mill and reported that the grinding rate can be predicted through the measured impact energy

IsaMillWikipedia

The IsaMill is a stirred-medium grinding mill in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
