Abstract
A rotating throat pulverizing mill has a soft steel vane wheel which rotates with the control bowl for classifying purposes. Wear-resistant vane liners slide onto the vanes to protect the upper surfaces thereof and are held in place, in part, by integral clips which underlie the vane plates and, in part, by wear-resistant cap plates which are welded to a flush upper flange of the vane wheel. Arcuate wear plates are also welded to the exposed surfaces of an air deflector outboard of and above the vane wheel. The vane wheel is preferably constructed in segments. A modified deflector assembly comprises a first portion having a base plate and spaced vertical ribs, which first portion is bolted to a lower deflector, and a box-like, wear-resistant cover assembly which seats on the ribs and is welded to the seat blocks by ways of access holes.
