The electromagnetic heating rotary kiln for solid waste is a high-end environmentally friendly equipment developed by Zhengzhou Dingli Group specifically for the harmless treatment and resource recycling of solid waste. It employs advanced electromagnetic induction internal heating technology, using clean electricity as a heat source to replace traditional coal-fired and gas-fired heating methods. This completely solves the pain points of traditional solid waste treatment kilns, such as severe pollution, high energy consumption, and incomplete treatment. It is widely used for drying, carbonizing, incinerating, harmlessly treating, and regenerating various types of solid waste, including industrial solid waste, municipal solid waste, and hazardous waste. It is a core piece of equipment for practicing a green circular economy and achieving solid waste reduction, harmlessness, and resource recovery.
The Dingli electromagnetic heating rotary kiln for solid waste is suitable for various industrial solid wastes, including smelting slag, chemical slag, electroplating sludge, furnace slag, oil sludge, municipal sludge, domestic waste, medical waste, and waste batteries.

1.The electromagnetic heating principle of a rotary kiln is primarily based on electromagnetic induction. When an alternating magnetic field acts on a conductive material, an induced current is generated within the material. These induced currents generate heat as they dissipate electrical energy in the resistance. This heating method is called electromagnetic induction heating.
2.In a rotary kiln, electromagnetic induction heaters are installed on one or more sides of the kiln and contain one or more electromagnetic coils. When a high-frequency current passes through these coils, they generate an alternating magnetic field. This magnetic field can penetrate the kiln body and act on the material within.
3.The rotation of the material within the rotary kiln ensures that it is heated uniformly as it continuously moves between heating and cooling zones. This rotational mixing ensures that the material is heated evenly throughout the entire rotary kiln, achieving efficient and uniform heating.
