The invention comprises a coal-fired burner system for use in a drum mix asphalt plant or drum dryer used for producing asphalt paving composition. Coal to fire the burner is ground to a -200 mesh size by an air-swept rotary impact mill, and a classifier at the exit from the mill controls the size of the particles leaving the mill.
Jan 27, 1987 · Accordingly, there is a need to provide a coal-fired asphalt plant which allows instantaneous control of the burner without the storage of large quantities of pulverized coal. Typically, coal for burning in an asphalt plant has been pulverized without specific regard to classification of the particle size.
As for the efficiency and low emissions of the coal-fired burner, Catlett says the burner only uses 16 pounds of coal to produce one ton of HMA. The ash produced by burning coal is minimal — approximately 1.25 pounds per one ton of HMA — and does not affect the quality of the mix.

asphalt plants in the United States. Of these 3,600 plants, approximately 2,300 are batch plants, 1,000 are parallel flow drum mix plants, and 300 are counterflow drum mix plants. The total 1996 HMA production from batch and drum mix plants is estimated at about 240 million tons and 260 million tons, respectively.
