1, The importance of crushing process:
Conducive To Mineral Enrichment: the vast majority of processing ore concentrator are useful minerals and gangue minerals closely together with students, and often into fine particles and even fine-grained disseminated. Only they are crushed, full dissociation, in order to use existing physical beneficiation methods enriched them.

Easy Sorting: all physical beneficiation methods are limited by particle size, particle size is too coarse (useful minerals and gangue unrealized dissociation) or size too small (ie, over crushed to fine particles) can not be effectively sorted. In all aspects of the concentrator, the ore crushing process is the highest cost is an important part of the concentrator constituting investment and production costs.

2, Mining crushing process
In metal ore beneficiation process, the task of crushing operations follow the “more broken and less grinding” principle, for grinding operations to provide suitable feed size, or sorting, metallurgical, construction and other direct use of suitable size. Crusher located in the most forward position in the mineral processing equipment, which determines the performance of the mine production capacity.

HJ  jaw crushers is a low-power high-energy, high capacity in one of the high-performance crusher can be widely used in metal and nonmetal mines, cement, construction, sand and metallurgical industries, the biggest strength of crushed material 320MP. Practice has proved that energy HJ series jaw broken by the good performance, reliable quality and cost-effective, has become the traditional jaw crusher ideal upgrade alternative.
