Another key reason rotary kilns are chosen is their high capacity. A direct-fired kiln can process anywhere from 1 to 25 tph (0.5 to 22 metric tph) of material, while indirect-fired kilns can process between 200 lb/h to 20 tph, making them an ideal option for high-capacity settings such as mineral processing and the production of roofing granules.
