Nov 01, 2017 In your first compartment the grinding is not related to surface area at all and it is related to weight and number of impacts. In the second compartment the grinding is related to pass of contact or length of circumference (see attachment). But you should figure the ball charge base on how it is grinding along the length of the compartment.

Stage 4: Finish Process Cement Production

A ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. The smaller grades are occasionally cylindrical (“pebs”) rather than spherical.

Millstone Wikipedia

Millstones or mill stones are stones used in gristmills, for grinding wheat or other grains.. Millstones come in pairs: a convex stationary base known as the bedstone and a concave runner stone that rotates. The movement of the runner on top of the bedstone creates a “scissoring” action that grinds grain trapped between the stones.
