FAQ
What Is Electric Rotary Kiln?
Electric rotary kiln is a type of rotary kiln that uses electricity as its heating source to indirectly heat materials in the kiln body. It is commonly used for high-temperature oxidation and reduction reactions, calcination of granular or powder materials, and other industrial applications. The temperature of the kiln can reach up to 1100℃, and it is widely used for the calcination and drying of various materials, including positive and negative electrode materials, rare earth materials, magnetic materials, and non-metallic mineral materials. Its advantages include high-speed electric heating, energy efficiency, and environmental friendliness.
How Does A Electric Rotary Kiln Work?
An electric rotary kiln works by gradually heating materials, such as minerals and ores, to very high temperatures using electricity as its power source. The kiln consists of a body, discharging device, electric heating device, and control unit. The electric heating device heats the surrounding environment of the materials in the kiln, and the temperature is monitored by a thermocouple. The kiln body has a certain inclination angle, with the feed end at a higher position than the discharge end. As the material rotates with the furnace tube, it passes through various temperature zones before being discharged.
What Are The Advantages Of Electric Rotary Kiln?
The advantages of electric rotary kiln include high thermal efficiency, no smoke, ash, or slag, easy automatic control of conditions, high kiln temperature control accuracy, and avoidance of corrosion and environmental pollution problems. Electric rotary kilns use clean electricity and do not require fuel storage or transportation stations. They are suitable for narrow pre-firing temperature processes and can be used for various materials, including positive and negative electrode materials, rare earth materials, chemical catalytic materials, and non-metallic mineral materials. The electric rotary kilns by KinTek feature high-speed electric heating, intelligent PID thermal control technology, and excellent dynamic sealing technology for inert gas protection.
What Can Electric Rotary Kiln Be Used For?
Electric rotary kiln, also known as rotary kiln electric furnace, is used for high-temperature oxidation and reduction reactions, and for calcining granular or powder materials. It is widely used in industries such as rare earth materials, nonferrous metal materials, chemical catalytic materials, powder metallurgy materials, and kaolin non-metallic mineral materials.
