Abstract
A shoe bracket assembly is described for mounting an impeller shoe to the horizontal rotatable turntable of a vertical shaft centrifugal crushing machine. The shoe bracket includes removable wear protector plates on opposed end faces thereof. The plates protect the rigid base member of the bracket assembly against wear. The wear plates are slidably mounted to the base member by slidable dovetail connector members and are locked into place between abutment surfaces on the base member and a back face surface of the impeller shoe. The plates can be easily removed and replaced following removal of the impeller shoe.

In a vertical shaft impact crushing machine having:
- a rotatable horizontal impeller turntable;
- a removable elongated impeller shoe mounted on the turntable, said shoe having an elongated back mounting face extending along the length of the shoe between an inner end and an outer end;
- an upright bracket member mountable to the turntable and having a front face and opposed side faces;
- wherein the front face of the bracket member has a width that is less than the length of the impeller shoe to receive and mount the back surface of the impeller shoe, with the ends of the shoe extending beyond the side faces of the bracket member;
- wherein the improvement comprises:
- wear protector plates, each having a bearing face a wear face, and a forward end face;
- and
- means for releasably mounting the wear protector plates to the side faces of the bracket member with the inner and outer end of the impeller shoe overlapping the forward end faces of the wear protection plates to secure the wear protector plates in place when the crushing shoes are mounted to the shoe bracket.
