For the study of these profiles we consider a rotary kiln with a diameter of 0.4 m and a length of 2 m operated at an inclination of 3 °. The dam height is 2.5 cm. These dimensions are different from the actual rotary kiln used in the pilot plant which are omitted due to …
Equipment Used. Rotary kilns are used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or indirect-fired type.It is also common to follow the calcination process with a rotary cooler. This efficiently cools the material after it has been calcined, so it ...

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.
bed and the rotary kiln. A dual approach was taken: at ARRADCOM a fluidized bed incinerator was planned and funded for evaluation, while a "best available", off-the-shelf rotary kiln was installed at the Radford Army Ammunition Plant. Both were operated on the pilot plant scale. The present value unit cost (PVUC) method of analysis was used
