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). Smelting and refining. Ball mills are employed in the comminution stage as grinding machines ( size reduction ).

Ball mill Wikipedia

Ball mill Wikipedia

It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls.
