ROTARY
TUBE FURNACES
RTC Series - Models to 3100F (1700C)
FOR DYNAMIC DRYING, CALCINING AND OTHER HEAT TREATMENT
OF POWDER. The key to producing uniform, heat
processed powders and granules is equal thermal
treatment of every particle.
UNIQUE/PERENY
Rotary Tube Furnaces are specifically designed
for continuous, dynamic drying, decomposition,
sintering, calcining and other heat treatment
of powders and granules at temperatures up to
3100o F (1700o C). These furnaces are routinely
operated in air or other atmospheres to process
traditional and advanced materials such as ferrites,
titanates, nitrides, metallics, aluminas, carbides,
catalysts, reducible oxides and minerals.
The Rotary Tube Furnace offers advantages over
static or batch processes because material flows
freely through a sloping, heated rotating tube
where it is tumbled constantly, causing uniform
heat treatment of every particle. Both the slope
angle and the rotation speed may be varied to
provided a wide range of material throughput rates.
Indirect heating and multiple temperature zone control provide the means to adjust the temperature
profile of the process. Electric or gas fired
production and pilot scale models are available
with ceramic or metal alloy tubes with atmosphere
capability and various materials handling accessories.
