ABSTRACT:
A pulverizer roll wheel assembly comprises a bracket with an opening therein for fixing the outer end of a roller shaft. Bearings mount a roller wheel with pulverizing tire to the inner end of the shaft for rotation of the pulverizer. A lip seal assembly separates an oil space around the inner end of the shaft with an air space around the outer end of the shaft. A pop off relief valve normally positioned near the lip seal is repositioned to the outer face of the shaft for easier access. A cover extends over the relocated valve for extending the air space around the relocated valve.
