| Abstract: | For solving the problems of lower impact toughness,lower resistivity to wear and shorter service life, witch presented in the conventional hammer head of the centrifugal type crusher, the improvement measures are put forward, based on the analyzing of hammer head wearing mechanism and wearing condition. Adopting the method of the solld-liquld composite casting, the new type anti-impact and anti-wear hammer head , in witch the soft material and hard material are alternately arranged, were made. Through applying it in crusher, the satisfactory effect shows its service life extended to 3.5 times as much as the original alloy steel hammer head. |
