ABSTRACT:
A removable rotating annular passage segment having a removable vane design is achieved by welding individual carbon steel parts into place. A welded passage segment having rails secured by a plurality of ribs is mounted to the grinding table of a pulverizer. Casted vanes are detachably mounted to the welded passage segment and are refitted when worn. The outer wall is adjustable and replaceable because it is welded to the pulverizer. Flow contour plates are welded to both the inner rail and outer wall.
