The grinding rate constant is one of the important factors needed to measure or evaluate a grinding process. It has been found that the decreasing rate of the feed size is described by a first-order equation in the initial grinding stage of various mill types.
The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form he fine product by reducing void spaces between the balls.
