ABSTRACT:
Apparatus for pulverizing coal including a bowl and a cooperating roller between which members the coal is pulverized. The grinding surface of the roller is made up of a removable sleeve which is securely held on the journal bearing housing by means of wedge lock rings located at each end of the sleeve. These wedge lock rings, along with the roller, can be easily assembled, and provide positive locking of the removable sleeve onto the journal bearing housing, even if there are slight irregularities on the tapered surfaces of the sleeve.
