Rotary calciners, also generally called indirect kilns, are utilized 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. Unlike direct- fired kilns, which use direct contact between the material and process gas to carry out processing, in a calciner, heat is transferred from the shell of the externally heated kiln to the bed of material through radiation.
HENGYANG offers a unique testing facility where we utilize batch and continuous pilot equipment to simulate manufacturing conditions, allowing us to test small samples of your material under various conditions and develop a process around the unique requirements of your material. Specifically, we offer a direct batch kiln, circular batch kiln, direct continuous kiln, and indirect continuous kiln.
The batch and pilot direct-fired equipment can be configured to include the following: combustion chamber, afterburner, Baghouse, quench chamber, and wet scrubber.
