ABSTRACT:
An improved hammer design for a swing-hammer type crushing machine. The hammer is in at least two pieces, a shank and a detachable tip section. The shank is pivotably mounted at one end on a rod extending between a pair of radial discs spaced along the machine rotor. The tip section is joined to the shank by a simple connecting pin which passes through co-aligned holes in a bifurcation on the tip and a lug extending outwardly from the shank. Spaced apart tabs at the free end of the shank co-operate with a stop on the rotor to limit the pivotal movement of the hammer between predetermined limits such that the connecting pin is always confined between the pair of rotor discs during operation of the machine. However, a worn or damaged tip section can be readily replaced in situ by removing the rotor stop, pivoting the hammer so the connection between the shank and tip are outside the rotor, and removing the connecting pin.
