Mineral Processing

 · PRODUCT SIZE • The target product size required from the crushing circuit will determine the number of crushing stages and types of crushers to be used for a specific application. • E.g.. To produce a coarse product a single stage crusher may be required. • To produce a 15 mm product a two stage crushing may be required.


The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.
