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.
