What Is the Role of Crushing in the Beneficiation Process?

The ore is crushed, chunks of ore or ore to be processed by means of external forces to overcome its internal intermolecular force broken, the nugget size diminishing. In the beneficiation process, crushed ore is usually divided into two major stages of the crushing (coarse stage) and grinding (fine stage).

In concentrator plant, ore crushing material preparation stage is essential before the sorting operations. First of all, the vast majority of the ore concentrator processing useful minerals and gangue minerals are closely linked born together, and often a fine and even fine-grained disseminated. Only to crush them, fully dissociate in order to use the existing physical beneficiation methods they are enriched. Secondly, all the physical beneficiation methods are subject to the limitations of the particle size, particle size is too coarse (useful minerals and gangue unrealized dissociation) or size too small (ie, crushed fine) can not be effective sorting. Various links in the concentrator, crushed ore is the most expensive process, constitute an important part of the concentrator of investment and production costs. Therefore, the basic task of the ore crushing operations is sorting operations suitable selected materials. The   good or bad crushing process, directly affect the technical and economic indicators of the dressing.

Ore crushing equipment

The crushing equipment can adopt the jaw crusher, impact crusher (sand making machine), cone crusher, hammer crusher, double roll crusher and other. Different feed size, discharge size, use of the different crusher.

Jaw crusher is divided into coarse and fine broken two kinds, coarse broken feed size 125mm-1020mm (production capacity, the feed size), broken into small fineness between 125-250mm .The expected size of the crusher can be adjusted, mainly for highway and stone production line.
The impact crusher is mainly used in the production of construction sand, the sand used in construction equipment....
