Impact crushers are being widely used in fields of mining, aggregates production, cement manufacturing and chemicals. Compared with developed countries, impact crusher development in our country is rather late. By the time of 1980s the technology gaps of impact crusher was fulfilled. Although we have legged behind others for about 20 years, through the joint efforts of enterprises that manufacturing crushes, we have already narrowed down the technology gap with developed countries.
