ROTARY KILN CONSTRUCTION. While FEECO rotary kilns are custom designed around the material to be processed, in general, there are some standard components that serve as the basic design of a rotary kiln. The diagram shown on page 8 illustrates some of the common standard components found on a basic direct-fired kiln.

· A rotary kiln is a cylindrical vessel that rotates around its axis, used in a variety of industrial processes. The activation process in a rotary kiln involves three stages: drying, pyrolysis, and activation. In the drying stage, the raw material is heated to remove any moisture content. In the pyrolysis stage, the material is heated to a high

A rotary kiln incinerator breaks down or decomposes material into simple compounds via complete combustion, converting wastes to an ash residue and thereby significantly reducing waste volume. To achieve this, a direct-fired, refractory-lined rotary kiln uses a co-current (parallel) configuration, in combination with an oxygen-rich environment.
