Rotary Tube Furnaces

UNIQUEPERENY 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
