the production capacity of the mill can be subdivided into two parameters, namely the production capacity of the mill and the capacity per unit mill volume. (1) production capacity of grinding machine. this parameter refers to the amount of ore processed by the mill per hour, in units of t/(station •h), at a given ore feed and product size.
