Stone crushing plant Working flow chart

Hopper -> Vibrating feeder -> Primary jaw crusher -> secondary impact crusher -> tertiary cone crusher -> fineness VSI crusher -> vibrating screen -> stockpile

The Big size stones are transferred to primary crusher (PE jaw crusher or PEW jaw crusher) through vibrating feeder from hopper for first crushing, then the crushed materials (small size) are transferred to impact crusher(PF impact crusher or PFW impact crusher) through belt conveyor for secondary crushing. The materials crushed will be transferred to the vibrating screen, and separated to different sizes. Those aggregate with suitable size will be transferred to the final product pile and those with unsuitable size will be transferred to the impact crusher for re-crushing. These forms a closed circuit manifold cycles. The sizes of final products will be graded and separated according to customers’ requirements, and the Bag Dust Filter will be attached for the sake of environment protection.
