finer the coal, the coal and air mixture characteristics are closer to a fluid than solids in suspension. The more fluid coal/air mixture makes achieving complete homogenization of the mixture leaving the pulverizer much easier. A more homogenous mixture of air and coal results is more even distribution between burner lines. EL Pulverizers

Integral fan purges the pulverizer of coal dust after the coal feed is stopped As raw coal and primary air enter the crusher section during start-up, air temperature is lowered as coal moisture is evaporated and only relatively cool air comes in contact with the pulverized coal Easy Access for Maintenance
