I. Overview of Heating Characteristics of Microwave Rotary Kiln Equipment:

Microwave high-temperature rotary kiln equipment heats materials by absorbing microwave energy internally, making the material itself the heat source. It is applicable for calcination and synthesis of high-melting-point powdered or granular materials under air or protective atmospheres, as well as pyrolysis treatment of high-melting-point organic solid waste (such as industrial waste salt, rare earth ore powder, metallurgical ore powder, etc.). This equipment offers high energy utilization, uniform heating, excellent product quality, short calcination or pyrolysis cycles, and high production efficiency. The microwave rotary kiln enables automated feeding and discharging, eliminating the need for saggars or push plates. It utilizes a spiral shaft to flip and advance materials dynamically for heating, offering convenient operation, reduced equipment investment and maintenance costs, and easy integration with intelligent and automated feeding and discharging systems. It is an ideal microwave furnace type.

II. Introduction to the Unique Heating Principle of the Microwave Rotary Kiln:

Heating principle of the microwave high-temperature rotary kiln: Microwaves are a form of electromagnetic waves. Under the influence of a high-frequency microwave electromagnetic field, polar molecules in dielectric materials generate intense friction, producing heat. By absorbing microwave energy internally, the material itself becomes the heat source. Microwave heating differs from conventional heating in that it is a non-contact internal heating method, where the material heats uniformly throughout without the need for heat conduction. Conventional heating relies on thermal radiation, convection, and conduction, transferring heat from the outside in, resulting in high heat loss, low efficiency, prolonged heating time, uneven heating, tendency for coking, large exhaust gas treatment volume, extensive kiln infrastructure, rough production environment, and the need for regular furnace cleaning, shutdown maintenance, and replacement, which is time-consuming and costly.

Microwave heating features rapid heating speed, selectivity, catalytic properties, non-direct contact between the heat source and material, ease of automation, and energy savings. Characteristics of microwave industrial kilns: Energy-saving (high conversion efficiency to heat, saving over 30% compared to traditional heating methods), environmentally friendly (no external emissions, effectively reducing harmful substance generation), clean (materials heat by absorbing microwaves themselves, no contact pollution, improving product quality and yield), high thermal efficiency (fast heating speed, high energy utilization). ZhongSheng microwave industrial equipment operates at temperatures up to 1600°C, with kiln temperature stability of ±5°C, easily integrated with automated and intelligent operation equipment, improving the production environment.
