The working principle of rotary kiln electromagnetic heating equipment is based on electromagnetic induction heating technology. High-frequency current is used to generate an alternating magnetic field inside a conductive object, which in turn generates an eddy current effect, causing heat to be generated inside the object, thereby achieving heating.

Specifically, electromagnetic induction heating equipment is mainly composed of the following parts:

1. Power supply equipment: Provides high-frequency current, usually a high-frequency inverter power supply, and can adjust the frequency and power as needed.

2. Induction coil: Converts the current of the power supply into an alternating magnetic field, usually a coil wound with copper wire, and controls the heating area by adjusting the position and number of the coil.

3. Cooling system: Since the induction heating device generates heat during operation, a cooling system is required to maintain the normal operation of the equipment.
