This series can deal with materials with feed size less than 500mm. and compressive resistance not more than 350MPa despite of the large. medium or small size hard materials (granite. limestone, concrete). This machine Is widely used in mining. highway and rail road. construction stuff and other relative Industries and Its capability is prior to the cone e rusher and the hammer crusher. 

It Is a kind of crushing equipment, using impact energy to crush materials. When mate rials get into the area where the board hammer plays a part, under the impact function of board hammer at a high speed. the malted ones are thrown to the impact device above the rotor continuously. And then they are rebounded from the impact liner to the area where the board hammer plays a part, and are impacted again. The materials from large to small get into the impact cavity for being crushed repeatedly. The process is going on until the materials are crushed to the required sizes and then discharged from down part of the machine.
