  • Clear-trajectory rotary-driven impact comminuter
    Patent number: 5544820
    Abstract: This invention relates to an apparatus for comminuting rock and other material and, in particular, to a rotary driven blade apparatus which comminutes rock, drilling materials and other material by impact rather than by grinding or crushing. More particularly, the invention creates a comminution environment which maximizes the establishment of a clear trajectory for the material between the orbit of each spinning blade and a single breaker bar.
