Modifiion Of Coal Mill Discharge Abstract

An improved coal pulverizer classifying system including a classifier cone extension to protect coal flow into the pulverizer from the annular fine-lifting airflow from the pulverizer throat. The classifier cone extension replaces traditional intermittent discharge structure, improving flow through the classifier system and reducing the disruptive effects of the discharge on the annular flow.
