    Blow bar( hammer plate) is the wear parts of the impact crusher. We use high chrome steel with Mo,Ni as the material.

    Blow Bars are installed on the rotor and they can prevent the rotor from being impacted by stones. Because Blow Bar always impacts the materials that are to be crushed directly, it is worn out easily.
