Box Crusher is also named heavy hammer Crusher. It is the new crushing equipment in the limestone area in recent years.  Box stone crusher is applicable to crush all kinds of materials with the superior hardness of the compressive strength as the first and second grade crushing .Our box stone crusher is especially used in mining, building materials, chemical industry, and metallurgy industry .

Work principle:
When materials get into work area , under the impact function of board hammer at high speed, the crushed materials are thrown to the impact device above the rotor continuously. And then they are rebounded from the impact liner to work area , impacted again. Materials whether large or small are crushed in cavity repeatedly. The process is going on until the materials are crushed to required size and discharged from bottom of the machine
