An improved coal pulverizer classifying system in which the feedpipe and classifier cone are provided with extensions to protect coal flow into the pulverizer from the annular finelifting airflow from the pulverizer throat. The feedpipe and cone extensions replace traditional intermittent discharge structure, improving flow through the classifier system and reducing the disruptive .
A deflector disposed immediately above and outboard of a rotating vane wheel in a pulverizer/classifier is protected from wear and abrasion by sidebyside abutting highhardness 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.
