  • Imply the external refining technology, effectively reduced the harmful elements, impurity 
    and oxygen and hydrogen harm, greatly enhanced the abrasion resistance and impact toughness of the steel
  • Using proprietary metamorphic agent for modification treatment, fine grains, improve carbide
  • Configuration and distribution, and to improves the abrasion resistance and tenacity
  • Optimizing heat treatment process, make the product of uniform hardness especially,
    impact abrasion resistance becoming stronger

Our production base can supply the according hammer for the listed impact crusher on our website. Besides can also supply the customized OEM service against the drawing ,drawing No and specification. We can supply the one-stop service for you on this area if you have many different sizes and brands to be fitted.
