  • WEAR PLATE ASSEMBLY FOR VERTICAL ROTOR OF A PULVERIZER
    Publication number: 20090242679
    Abstract: A wear plate assembly includes a body portion and an abutment flange extending from a radially outer circumferential edge of the body portion and substantially normal thereto. The abutment flange is 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 are substantially aligned therewith at a same latitude on the body portion, the recess further includes a through hole extending through the wear plate. A first clip configured is partially received in the polygonal recess, the clip having a plurality of exposed impact surface faces.
