Classifier In Coal Pulverizer

A deflector disposed immediately above and outboard of a rotating vane wheel in a pulverizer/classifier is protected from wear and abrasion by side-by-side abutting high-hardness wear plates having an alloy content of approximately 15 percent chromium and three percent molybdenum by weight. The abutting edge surfaces of the wear plates are mitered.
