Get PriceRotary Calciners. Rotary calciners, also commonly called indirect kilns, are used in various calcination operations where exhaust gases must be minimized, when processing finely divided solids, or where temperature must be tightly controlled along the length of the kiln.. A calciner is comprised of a rotating drum inside a furnace, which is externally heated.
Get PriceRotary kilns work by processing material in a rotating drum at high temperatures for a specified retention time to cause a physical change or chemical reaction in the material being processed. The kiln is set at a slight slope to assist in moving material through the drum. Direct-fired kilns utilize direct contact between the material and ...
