Indirect drying in rotary calciner

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
