Abstract
A bowl mill pulverizer includes a mill housing supported on and extending upwardly from a foundation. A milling bowl is supported within the housing for rotation about a vertical axis. A frame is located over the bowl with arms extending downwardly from the frame and rotatably supporting grinding rolls positioned within the bowl. Upwardly extending pull rods are secured at their upper ends to the frame and at their lower ends to the foundation. The pull rods press the grinding rolls downwardly against the bowl. The pull rods are disposed at an angle to the vertical and slope outwardly and downwardly toward the foundation.
