USA Rotating throat for coal pulverizer Google
A rotating throat pulverizing mill has a soft steel vane wheel which rotates with the control bowl for classifying purposes. Wearresistant 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 wearresistant cap plates which are welded to a flush upper flange of the vane wheel.
