Applications
This calcination rotary furnace is a 310S stainless steel inner cylinder externally heated rotary resistance furnace. It can be used for calcination and drying of granular materials such as lithium battery cathode and anode materials, as well as highly acidic and alkaline powders, in the laboratory pilot stage. Users can apply the appropriate atmospheric protection according to the material firing process. The production method is batch production, suitable for calcining powder materials.
Structural Description
This Calcination Rotary Furnace mainly consists of several parts: furnace body, lifting system, mechanical transmission system, inlet and exhaust system, etc.
1.1 Furnace Body
1.1.1 Furnace Frame: Divided into upper and lower layers, constructed from shaped steel and steel plates. The upper frame is primarily composed of two semi-circular metal shells connected together, containing furnace tubes, refractory material modules, insulation materials, etc. The lower frame houses the electrical control box and electric push rod. The bottom of the lower frame is equipped with four legs: two fixed and two movable wheels with a brake system on the movable wheels.
1.1.2 Refractory Material Modules: Composed made from vacuum-cast alumina alumina fiber.
1.1.3 Metal Furnace Tube: Fabricated from 310S pipes, with internal scraper blades of the same material.
1.1.4 Heating Elements: Constructed from iron-chromium-aluminum heating wire (0Gr27A17Mu2), embedded within the refractory material.
1.2 Lifting System
Controlled by an electric push rod, tilting the upper frame and furnace body within a range of -5° to +15°, capable of hovering at any angle within this range. The maximum positive angle of the upper frame is controlled by the travel switch integrated into the electric push rod. The negative angle is controlled by limit switches installed on the hinge supports, allowing the furnace to stop at any desired angle.
1.3 Mechanical Transmission System
The furnace body is driven by a chain transmission system, ensuring safety and reliability. The transmission system comprises a main drive motor with gearbox, chains, large and small sprockets, and front support wheel mechanism. The gearbox, with a power of 0.12 kW, allows the furnace tube speed to be adjusted between 1 to 3 rpm as required, enabling continuous rotation.
1.4 Inlet and Exhaust System
Both ends of the furnace body are equipped with rotary joints for smooth transition. The intake end of the furnace tail is equipped with pipe supports, stainless steel pipelines, ball valves, etc. Protective gas can be introduced as required during material calcination. The furnace door’s rotary head is connected to a ball valve and nozzle, allowing adjustment of the valve opening to control gas discharge based on the volume of material being processed. The flange sealing structure at the discharge port utilizes O-ring silicone seal.
1.5 Control System
The control box is located within the lower frame of the furnace body, housing electrical components such as air switches, power adjustment modules, etc. The controller is positioned at the front of the furnace body, allowing pre-programming of firing curves and fully automated heating. This system facilitates rotation of the heating furnace tube and tilting of the furnace body for easy material loading and unloading.
