1050 Large-scale Rotary Tube Furnace

The Model 1050SSR large-scale rotary tube furnace is an industrial thermal processing unit designed for the continuous heat treatment, calcination, roasting, activation, and drying of powders, granules, and bulk materials. Featuring an extra-long rotary tube, an independent multi-zone temperature control system, an automatic screw feeding mechanism, and a continuous discharge structure, the equipment ensures stable, continuous production. It meets the large-scale manufacturing requirements of sectors such as new energy materials, chemical materials, metallurgical powders, mineral processing, and environmental protection.

The equipment utilizes a 310S high-temperature resistant stainless steel furnace tube, a high-efficiency silicon carbide heating system, and intelligent PID temperature control technology.

Tube Furnace Product Features

1. Extra-long heating zone for large-scale continuous production

The heating zone spans 9,600 mm (with a total furnace tube heating length of 12,000 mm) and utilizes a 310S high-temperature stainless steel tube with an outer diameter of 500 mm and a wall thickness of 8 mm. This extra-long design is ideal for the continuous calcination of large volumes of material, significantly boosting the capacity of a single unit to meet industrial-scale production demands.

2. Five independent temperature zones with precise profile control

The system features five independent temperature control zones (Zones 1–5), each equipped with dedicated temperature control and monitoring points. Zones 1 E 2 are adjustable between 450°C and 600°C for material preheating, while Zones 3 through 5 are adjustable between 900°C and 1,050°C for high-temperature calcination. This five-zone design guides the material through sequential stages—preheating, heating up, high-temperature calcination, and cooling—ensuring precise control over the temperature profile. The furnace maintains a temperature uniformity of ±3°C and a control accuracy of ±1°C.

3. Large-diameter furnace tube with anti-stick internal structure

The furnace tube has an outer diameter of 500 mm, a wall thickness of 8 mm, and an inner diameter of 484 mm; UN 3,000 mm cooling section made of 304 stainless steel is installed at the discharge end to allow the material to gradually cool down before exiting the furnace.

4. Automatic feeding via screw feeder for stable, continuous production

A screw feeder is used for material input, with all contact parts made of 304 acciaio inossidabile. It is equipped with a variable frequency drive (VFD) supporting up to 50 Hz and a 1,500 W gear motor. The adjustable feed rate enables continuous, uniform, and stable automatic feeding, making it suitable for large-scale industrial continuous production.

5. Adjustable tube rotation and tilt for controlled material flow

The furnace tube rotation drive system features a 3000 W motor equipped with a variable frequency drive (up to 50 Hz) for adjustable rotation speed; a manual lead-screw mechanism is used to adjust the furnace body tilt angle within a range of 0 to 3 degrees.

6. Sealed furnace tube ends enabling a slight positive-pressure atmosphere

Both ends of the furnace tube feature effective sealing arrangements—specifically, graphite packing at the feed end and graphite seals at both ends. The feed end is equipped with an exhaust butterfly valve (DN60), while the discharge end is fitted with a discharge butterfly valve (DN80) and an oxygen inlet. This semi-sealed structure at both ends allows for the maintenance of a slight positive-pressure atmosphere within the tube, meeting the atmospheric requirements of different materials.
