Counterattack Crusher function 100~500 mm on a side item, the compressive strength of up to 350 MPA, with high crushing ratio, broken mine a cube of material particles and so on. Equipment, small size, simple structure, high crushing ratio, low energy consumption, high productivity, equal product granularity, and the crushing effect of selective, is a promising device; older impact crusher is the Chief drawback of the hammer and the impact plate is easy to wear, especially broken hard ore, wear and tear is more serious, the need for frequent replacement. Now appears in the new wear-resistant steel materials of inversed impact crusher has been applied, changed the course of this
