Rotary 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.

A Rotary Kilns is a Direct Fired, Refractory Lined equipment for high temperature applications where it is necessary to change the state of the material in a continuous process or in batch type process. Since this process usually requires a long residence time, the length to diameter ratio is often in excess of 101 in a continuous kiln. In most cases an oil or gas burner fires directly into ...
