pulverizer grinds in coal
General System of Coal Pulverizer | Power Plant Technology
Coal from the bunker enters the coal feeder which conveys the coal to the pulverizer for grinding and drying. The processed pulverized coal is passed through a classifier by the drying agent (primary air). There are four pulverized coal pipes (φ590×10) connecting each classifier to supply coal to burners on the same layer in the four corners ...

Make sure that the grinding surface profiles are optimum. That means using the original design grinding profiles for your mill. The majority of coal pulverizers sized around 120,000 pph use three grinding elements, referred to as journals, rolls, or tires. For best results, all three grinding elements should be replaced in matched sets.
