The Linn High Therm GmbH presents a new rotary tube furnace for special heat treatments of powders and granules with ceramic or metallic rotary tube (inner diameter = 500 mm, length = 8,700 mm, heated up to 6,000 mm). The furnace has an adjustable rotation speed (from 0,5 to 5 rpm) of the insert tube and an adjustment of inclination up to 3°.
The rotary tube furnace has a 5-zone heating: Fibrothal half shells with embedded heating coils, Tmax 1,150 °C. The rotary tube cooler offers cooling of the product after the heat treatment for immediate product handling. The product is cooled through indirect water cooling. Stainless steel rotary tube: di = 600 mm, L= 4,000 mm, cooled up to 3,000 mm.
The following options can be selected: protective gas, screw conveyor, thermal post-combustion, multideck sieves, cooling zones, vibration feeder, rotary valve, level sensor.
Insert tubes: quartz Tmax < 1,100 °C, PM alloy < 1,250 °C
Electrically heated rotary tube furnaces are used for continuous drying, oxidizing of chemicals, reducing of metal oxides, calcination and sintering of ceramic powders and granules, metal heat treatment etc.
