Zinc Oxide Drying and Calcination Equipment
Introduction to Zinc Oxide Drying and Calcination:
The current zinc oxide products are mainly active zinc oxide, high purity zinc oxide and nanometer zinc oxide. The dynamic zinc oxide drying and calcination equipment developed by our company is the most advanced process equipment and technology.
Product Introduction:
The traditional production methods of zinc oxide by the zinc carbonate mainly are: One is shaft kiln, and the other is the use of rotary kiln. The zinc oxide so produced is of low activity, high energy consumption, heavy environmental and material pollution and waste. Applying the dynamic drying and calcination process equipment developed by our company can produce the zinc oxide with high activity and purity. The zinc oxide flash drying calciner is of the features of energy saving, without environmental pollution, high recovery efficiency, small land covering area and high automation level.
Working Principle:
The exhaust which is generated from the material calcination in the dynamic calciner enters into Si De dryer, and the filter cake-shaped zinc carbonate with moisture content from 30 to 50% is fed into the dryer, the powdered zinc carbonate via break up and drying enters into the dynamic calciner, the hot air generated from coal, natural gas or gas enters into calciner to carry out mixed heat transfer with the zinc carbonate in the calciner, upon the heating under hot air of 400~1000 Celsius, the zinc carbonate, after fast decomposition for a few seconds, is decomposed into zinc oxide, and the decomposed zinc oxide enters into silos via trap.
Performance Features:
1. Decomposition temperature is even and fast, which can realize the zinc oxide production with high activity and high purity, activity of> 80, purity> 99.
2. The filter cake-shaped zinc carbonate will be produced into powdered zinc oxide in a single piece/set of system
3. Heat consumption for production 150~200× 104kcal/ton.
4. Without environmental pollution, small land covering area, convenient for maintenance and operation, high automation level.
5. Recovery rate> 99%
Technical Specifications:
Within the series of models, a single piece/set of equipment can produce zinc oxide1000, 2000, 3000, 5000 tons per year.
