Rotary Calciners
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.

Gas suspension calciners from FLS
Hot calciner off gas flows to multiple cyclone preheaters, which transfer the heat into incoming raw materials. Meanwhile, hot calcined materials flow to cyclone coolers, which capture the heat from these solids and transfer it to the incoming air stream. This dual heat recovery significantly reduces the fuel consumed in the flash calciner.
