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
