By adopting the developed technology and unique structural design, finished products processed by impact crusher boasts cubic shape without tension and cracks. It can crush stone smaller than 500mm with the compression strength lower than 350MPa, such as granite, limestone, concrete, etc.
Impact crusher is widely used in all kinds of ore crushing, railway, highway, energy, cement, chemical industry, construction, etc. the output size can be adjusted.
 
Performance features
PC hammer crusher has all advantages of impact  and hammer Crusher ,it has  reasonable structure, stable performance, large crushing ratio, uniform discharge good granularity shape, high-yield and low consumption, easy maintenance, less wearing parts, especially crushing limestone, coarse, medium, crushing only one step, instead of the traditional two crushing process, low investment in infrastructure and equipment, supporting the vibrating feeder without manual operation, higher yields and more economical.
 
Principle of operation

The main parts of efficient compound crusher is rollers with hammer, the rollers consists of main shaft, sphere plate, axis roll and hammer. Motor drives roller in high speed running inner the crushing champ, the materials is send from top into the crusher, by the striking, impacting, shearing and grinding into power. At the roller bottom is a screen plate, it is used to collecting the materials whose size bellow the size of the screen plate, those size is bigger than the screen gap will be regrind by the hammer, finally discharged from the discharging opening.
