提高锤式破碎机锤头使用寿命的研究

讨论了PCK1010锤式破碎机锤头磨损机理，损坏原因。将传统的砂型整体铸造工艺改为固液／溶融复合铸造，制造形成了软硬相间的耐冲击、耐磨损复合锤头，提高锤头使用寿命3倍，年节约备件费用可观。

The wear mechanism and damage reasons of the hammer head of PCK1010 hammer crusher are discussed. With conventional mould solid casting process changed into solid-liquid melting compound casting process, impact resistant and wear resistant compound hammer head has been manufactured with two-times usage life prolonged, which can save remarkable annual spare parts cost.
