External Heating Electric Rotary Kiln

Combined with the actual needs of customers, our company produced electric heating rotary kiln. It’s a new type of practical environmental protection rotary kiln equipment.The external heating rotary furnace has a compact structure, you can freely adjust the tilting angle and achieve precise control through temperature frequency adjustment. It also adopts modular design of heating elements, which is easy to replace. The equipment is easy to operate and convenient to maintain.


    Material: Lithium iron phosphate, battery recycling materials, coal-based (washed) kaolin, alkaline magnesium carbonate, magnesium hydroxide, magnesium chloride, molecular sieve (granular, powdered) catalyst, copper sulfate, barite, nickel oxide, titanium dioxide, zinc ore, sewage sediment, agricultural waste and industrial waste, etc.

    Application fields: Materials such as non-metallic ore, metal ore, medicine, food, chemical products and agricultural products

    Product Components: The external heating electric rotary kiln is mainly composed of six parts: combustion system, control system, heating chamber cylinder, kiln body, drive unit, feeding and discharging system, etc.

    Working Principle

    The material is delivered by feeder to enter the electric rotary kiln cylinder evenly. Driven by the transmission device, the material advances along the axial direction with the rotation of the cylinder, and the coping plate turns the material to make it calcine evenly. The cylinder is equipped with a heating chamber outside, and the heat generated by calcination is transferred to the material through the cylinder. Under the high temperature condition, the material goes through the process of decomposition, drying, calcination and roasting. After the calcination process, the material is discharged through the discharge valve, cooled and packaged for use.


    Flexible Adjustment of Tilting Angle
    The lower support device of external heating rotary kiln is adjustable support, which allows you to adjust the tilting angle according to your needs.
    Frequency Conversion Control of Temperature
    The heating temperature of electric rotary kiln can be precisely controlled by frequency conversion to ensure the heat treatment effect under different working conditions.
    Simple Operation and Operation Cost Reduction.
    Rotary kiln electric furnace is simple to operate, easy to grasp and operate, reducing personnel training costs and operating risks.
    The Cylinder is Heated Evenly and the Heat Loss is Reduced
    The rotary kiln electric furnace adopts electric wire heating or gas heating. There is a heat insulation cover outside, and the heating chamber is formed between the cylinder and the heat insulation cover, so that the cylinder is heated evenly and the heat loss is reduced at the same time.
