Online Course Article Ball Mill Introduction There are three main stages to mineral processing in the mining industry. These are: Comminution (crushing and grinding). Beneficiation (separation and concentration). The dry ball mill is a cylindrical rotating device that driven by an outer gear with two bins and a grid type ball mill. The material enters the first bin of the mill spirally What Are the Differences Between Dry and Wet Ball Mills?
