Heavy Box Crusher is a new type of crushing machinery designed by our company. It has born most of the virtues of jaw crusher, hammer crusher and impact crusher. Heavy Box Crusher is mainly used in mining, building, chemical industry and metallurgy for the primary and secondary crushing of materials.

3.Working Principles:

When materials get into the area where the board hammer plays apart, under the impact function of board hammer at a high speed, the crushed ones are thrown to the impact device above the rotor continuously. And then they are rebounded from he impact liner to the area where the board hammer plays apart, impacted again. Materials from large ones to small ones get into the impact cavity for being crushed repeatedly. The process is going on until the materials are crushed to required size and discharged from down of the machine.
