Abstract
The calciner is an elongated, insulated chamber, in which material is fed to counter-rotating screw conveyors. The material is calcined by heat radiating from a muffle plate interposed between the conveyors and gas-fired burners. This radiant heating, applied evenly to material having a constantly-exposed fresh surface, results in increased production, lower fuel cost per pound of product, and higher quality product.
