1. Working principle
Electric heating method: The electric heating rotary furnace uses electric heating elements to generate heat, which are usually placed on the outside of the furnace tube to generate continuous and stable thermal energy through the conversion of electrical energy. Compared with traditional combustion heating methods, electric heating has higher thermal efficiency and more precise temperature control capabilities.
Rotary design: The furnace body adopts a long cylindrical structure, lined with refractory materials inside to withstand high temperatures and maintain stability. The material is added from the high end of the furnace body, and as the furnace body slowly rotates and tilts, the material gradually moves downwards and is calcined in the high-temperature environment inside the furnace. Rotary design enables materials to be uniformly heated, improving processing efficiency and quality.
Temperature control system: Electric heating rotary furnaces are usually equipped with a good temperature control system, which can achieve precise control and adjustment of the temperature inside the furnace. This helps ensure that the material is heated evenly during the heating process, avoiding overheating or underheating.

2. Characteristics and advantages
Efficient and energy-saving: The electric heating rotary furnace uses electric energy as the heat source, which has the characteristics of high energy conversion efficiency and low heat loss, effectively reducing energy consumption and production costs.
Environmentally friendly and clean: During the electric heating process, there is no need to burn fuel, so no pollutants such as exhaust gas and smoke are produced, which is conducive to protecting the environment and improving working conditions.
Accurate temperature control: The temperature control system of the electric heating rotary furnace can accurately adjust the temperature, ensuring that the material is heated evenly during the heating process, and improving product quality and consistency.
Strong adaptability: The electric heating rotary furnace can adapt to different types of materials and process requirements. By adjusting operating parameters, designing structures, and adding equipment, it can process a variety of powder materials.

3. Application Fields
Metallurgical industry: used for processes such as melting, refining, and heat treatment of metals, such as calcination of bauxite.
Chemical industry: Provide stable and adjustable high temperature conditions to promote the smooth progress of chemical reactions, such as titanium dioxide production, catalyst preparation, etc.
Ceramic industry: precise control of temperature curve to ensure uniform heating of ceramic products during firing process, improving the yield and quality of ceramic products.
New energy materials: used for processes such as graphitization of negative electrode materials in lithium batteries, achieving ultra-high temperature treatment and improving material properties.

4. Calcination process flow
Raw material preparation: Pre treat the powder raw materials to ensure that their particle size and composition meet the calcination requirements.
Feeding: The pre treated powder raw materials are fed into an electric heating rotary furnace through a feeding device.
Calcination: Under the action of electric heating and rotation, powder raw materials undergo high-temperature calcination in the furnace, resulting in physical and chemical changes.
Cooling: The calcined material enters the cooling section for cooling, reducing the temperature to an appropriate range.
Discharge: The cooled material is discharged from the rotary furnace through a discharge device for subsequent processing or storage.

5. Precautions
Equipment cost: The equipment cost of electric heating rotary furnaces is relatively high, with a large initial investment, making it suitable for enterprises with sufficient funds or high requirements for product quality.
Power supply: Maintaining high temperatures requires a large amount of power support, and power supply issues need to be considered in areas with scarce power resources.
