Zhengzhou Dingli Lithium Battery Electromagnetic Heating Rotary Kiln is a high-purity, precision, and continuous thermal processing equipment specifically designed for the sintering of positive and negative electrode materials for lithium batteries and the resource recycling of spent lithium batteries. Utilizing electromagnetic induction internal heating technology and clean electrical energy as the heat source, coupled with a fully sealed atmosphere protection system, it perfectly solves the industry pain points of traditional gas/resistance kilns, such as temperature control differences, large pollution, batch instability, and high energy consumption. It is a core piece of equipment for high-purity lithium battery material preparation and efficient recycling of retired batteries.
Electromagnetic Rotary Kiln Working Principle:
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.
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.
When materials (such as ceramics, ores, powders,glass, batteries, organic solid waste, etc.) are placed into the rotary kiln, they rotate within the kiln. Due to the conductivity of the metallic components or conductive particles in the material, they are induced by the electromagnetic field and generate current. These induced currents generate heat in the resistance, thus heating the material.
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.
