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 mills are used in mineral processing and pharmaceutical applications. How does a ball mill work? Ball mill grinders work on the principle of impact and attrition. The ball mill machine contains a hollow cylindrical shell that rotates around its axis, becoming a tumbling ball mill. The impact of the balls that drop from the top of the shell ...
