###### Jaw Crusher

Jaw crushers are typically used as primary crushers, or the first step in the process of reducing rock. They typically crush using compression. The rock is dropped between two rigid pieces of metal, one of which then move inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.

###### Cyclone

The cyclone is widely used inc losed-circuit grinding system of Chinese black, colored, non-metallic mines;slurry dewatering, removing mud, micro-fine material grading,and tailings filling,dams,recycling and other process.As the cyclone is high classification efficiency, simple structure, large capacity, small footprint, etc., so it is widely favored by users.
