Abstract:
1. A wear plate assembly 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 assembly comprising: a body portion of a wear plate 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 opposite 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 flange extending from the radially outer circumferential edge of the body portion and substantially normal thereto, the abutment flange being cooperatively configured with respect to another abutment flange of a respective adjacent wear plate that interengages with the wear plate such that a convoluted edge of the another abutment flange of the respective adjacent wear plate intermeshes with a respective convoluted edge of the abutment flange of the wear plate; at least one polygonal recess and a corresponding abutment ramp substantially aligned therewith at a same latitude on the body portion, the recess further includes a through hole extending through the wear plate; and a first clip configured to be partially received in the polygonal recess, the clip having a plurality of exposed impact surface faces.
