AI Technical Summary

Technical Problem

Existing electromagnetic heating rotary kilns result in incomplete calcination of materials that are difficult to calcine, and extending the length of the barrel leads to excessively long equipment and a large footprint.

Method used

Design a variable diameter electromagnetic heating rotary kiln, which adopts an independent electromagnetic heating coil unit and a lifting plate structure. The inner diameter of the material cylinder is designed according to the heating and heat preservation areas. A moving magnetic field is formed by interleaved phase power supply. The material turning is optimized by combining the L-shaped lifting plate and the inclination of the material cylinder.

Benefits of technology

Without increasing the floor space, the calcination time of the material in the kiln is extended, the calcination capacity is improved, and the uniformity of the material is ensured.
