Zinc Oxide Rotary Kiln Product Introduction: 

Zinc oxide rotary kilns are a common method for processing zinc-containing intermediate materials and are also used as roasting equipment for calcining zinc. Zhengzhou Mining Machinery's zinc oxide rotary kiln is specifically designed for zinc oxide production. Because zinc oxide is a fine powder, we must develop a specialized rotary kiln specifically for this purpose, which we now call a zinc oxide rotary kiln.

Key Advantages

1. The zinc oxide rotary kiln has simple equipment configuration, reducing investment costs and improving productivity.

2. The zinc oxide rotary kiln has high beneficiation efficiency, producing high-quality zinc oxide with minimal nodules through calcination and smelting.

3. The entire zinc oxide production line operates smoothly, achieving high production capacity, and significantly reducing fuel costs during the smelting process.

4. The zinc oxide rotary kiln has simple equipment configuration, with a small number of units on the entire production line, ensuring that each unit performs at its full potential, ensuring a reasonable investment.

Operating Principle

The material entering the kiln is continuously rotated by the rotary kiln, moving toward the kiln head. The combustion of coke powder in the material releases heat, reducing the zinc in the material to zinc vapor at a certain temperature. Upon encountering oxygen, the zinc undergoes an oxidation reaction, converting it to zinc oxide, which enters the flue gas treatment system along with the flue gas. Once the burner is ignited, the material can self-sustain combustion, and the Roots blower only needs to continuously replenish air.
