The size reduction operation in the plant takes place as a sequence of crushing and grinding processes. In crushing, particles are reduced in size to such a level that grinding can be conducted, while grinding allows to achieve the desired liberation size. Besides, the process of comminution can be simple or complicated depending on the nature of the ore and the suitable degree of liberation.

Grinding equipment for mineral processing. The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.
