Mar 01, 1985An analysis of the novel Szego mill and its performance in dry grinding of coal and wheat is presented for open-circuit operation. The independent variables were the rotational speed of the mill, feed size and feed rate. Their effects on the dependent variables of product size distribution, power consumption and mean residence time are reported.

Performance Driven Maintenance of Coal Pulverizers
Good Performance Indication: • Adequate throughput • Minimal coal spillage • No rumbling • Recommended fineness •<0.1% retained on 50 mesh •>75% passing 200 mesh • Bright and attached burner flames • Low LOI (Direct impact of pulverizer performance) • Balanced airflow in fuel lines •Balanced fuel flow to burners

Nov 17, 2012Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% value is exceeded. Values lower

Coal Drying Improves Performance and Reduces
Predicted variation of the mill exit temperature (temperature of the coal-primary air mixture leaving the mill) with coal moisture content is presented in Figure 4. Until complete evaporation of fuel surface moisture entering the mill is achieved, the mill exit temperature is equal to the vapor saturation temperature.
