tion in beater wheel mills. The impact of different coal lithotypes (matrix coal, yellow, brown and black types of xylite-rich coal) from Kolubara lignite basin on grindability properties was studied in [11]. The yellow type of xylite-rich coal demonstrated the most negative impact on HGI. All xylite types, as...Mill type Beater wheel mill Vertical roller mill Fineness of pulverized coal 40-50% of a 200 mesh pass (estimation) 70-80% of a 200 mesh pass Features ・Frequent maintenance of the high temperature gas system ・Poor applicability to low-rank coals with low grindability, while there are many examples of coals with high

Hot flue gas is sucked into the beater wheel mill to dry the coal. While the coal is being pulverised, the coal dust is mixed with the flue gas, resulting in a high drying efficiency. The lignite/flue gas mixture is blown to the pulverised coal burner

Coal power| Beater wheel mills, also called ventilation mills, as employed in lignite fuelled power plants, are large and complex pieces of equipment (see Figure 1). Even for modern beater wheel mills, gas flow measurements are not generally accurate enough for them to be controlled by total instantaneous mass and energy balances...A numerical investigation is presented for a two-dimensional simulation of the gas flow field and of the dynamic behavior of lignite particles inside Beater Wheel mills with classifier, installed in large coal-fired plants.
