ABSTRACT:
A hammer assembly for a rotary material crusher having a rotor. The hammer assembly includes a hammer member and a base member. The base member is mounted at one of its ends on the rotor. The hammer member is mounted on the other end of the base member. The hammer member and base member each have two pairs of concave and convex surfaces, one for absorbing centrifugal forces and the other for absorbing impact forces and meshing, one surface with the other. The pair of concave and convex surfaces for absorbing centrifugal force are behind of the centrifugal force radial line of the hammer member in the direction of rotation of the rotor.
