A rotary kiln is a continuous process designed specifically for
drying, calcining, processing, or sintering bulk materials.
Rotary Kiln Process
The rotary kiln heated chamber is a long horizontal tube that is
rotated with one end slightly elevated. The bulk material is
continuously fed into the elevated end of the tube and cascades
down the length of the tube by the tube’s continuous rotation. The
bulk material exits the tube at the other end and falls into a
collection hopper. Depending on the required operating temperature
of the rotary kiln, the tube material will either be a high
temperature metal alloy or ceramic composition.
Rotary Kiln Design Requirements
The following information is required to determine the tube OD,
tube ID, tube length, tube rotation speed, the tube inclination
angle, and the tube material:
Cement
Lime
Refractories
Metakaolin
Titanium dioxide
Alumina
Vermiculite
Iron ore pellets
LECA Plant--Light Weight Expanded Clay Aggregate Plant
Oil Proppant/Frac Sand Plant
Slag
...............
