Patent ID: 7017844

Claim:
A wear plate for mounting in a wear protecting disposition on a rotor disc of a pulverizer, the rotor disc being rotatable about a rotor axis, the wear plate comprising: a body portion having a radially outer circumferential edge and a radially inner circumferential edge, an angular edge extending angularly between the radially outer circumferential edge and the radially inner circumferential edge on one side of the body portion and another angular edge extending angularly between the radially outer circumferential edge and the radially inner circumferential edge on an opposed side of the body portion, an axially inner surface disposed in facing relationship to the rotor disc in the wear protecting disposition of the wear plate on the rotor disc; an abutment shoulder extending from the radially outer circumferential edge of the body portion to the radially inner circumferential edge of the body portion along the one angular edge of the wear plate, the abutment shoulder having an linear elongate extent from the inner circumferential edge of the body portion to a location near the outer circumferential edge of the body portion, whereat the abutment shoulder has an overall curved hook shape terminating at the outer circumferential edge of the body portion; an underlap flange on the one angular edge of the body portion, the underlap flange extending in its width dimension outwardly in the angular direction from the abutment shoulder, extending in its length dimension from the radially outer circumferential edge of the body portion to the radially inner circumferential edge of the body portion and extending in its thickness dimension in the axial direction from the axially inner surface of the wear plate to a thickness less than the thickness of the abutment shoulder; and an overlap rim on the other angular edge of the body portion, the underlap flange being cooperatively configured with respect to an overlap rim of a respective adjacent wear plate that is in interengagement with the wear plate such that the overlap rim of the respective adjacent wear plate at least partially overlaps the underlap flange of the wear plate.
