Zinc oxide drier, calcination furnace system is introduced:
Active zinc oxide is widely used in: rubber, plastic, ceramic, feed, paint.
The current production of zinc oxide are mainly active zinc oxide, high purity zinc oxide and nano zinc oxide.Designed by our company research dynamic zinc oxide dry calcining process equipment is based on features of zinc oxide for the calcining process system, determine the calcination furnace technology, rapid decomposition, and can realize high active high purity zinc oxide production, specific surface area > 70, purity > 97.Good performance in the use, better than the traditional way, is a new type of advanced technology devices.
Product introduction:
Traditional zinc oxide from zinc carbonate production method of the main production: one is to use shaft kiln, the second is the rotary kiln.Produce zinc oxide activity is low, high energy consumption, serious environmental pollution and material waste.My company's dynamic drying calcination process equipment, can produce highly active, high purity zinc oxide.Zno flash dry calcining stoves with energy saving, environment friendly, high recovery efficiency, cover an area of an area small, high degree of automation, etc.
Working principle:
Will be produced by dynamic calcination furnace material after more than hot air supply, drier, feeder will be 30 ~ 55% water content of filter cake shape zinc carbonate into the drying machine, formed by the scattered drying powder of zinc carbonate in dynamic calcination furnace, hot air produced by natural gas into the sintering furnace, with the charging of zinc carbonate in mixed heat transfer, by the 500 ~ 900 ℃ hot air heating, zinc carbonate by seconds fast decomposition for active zinc oxide powder, after decomposition of the active zinc oxide by trap trap into the bunker.
Performance characteristics:
1. Uniform decomposition temperature quickly, and can realize high active high purity zinc oxide production, activity > 70, purity > 99.
2..Can be made of zinc carbonate in filter cake shape a sets production powdered zinc oxide in the system.
3. Production product, the heat loss of 150 ~ 200 x 104 kcal/ton.
4. Environmental pollution, cover an area of an area small, facilitate maintenance operation, high degree of automation.
5. Recovery > 99%
6. Use of calcination furnace flue gas waste heat supply zinc carbonate cake dryer dry, save energy.
Technical Specifications:
In the series model within a single set of zinc oxide production 1000,2000,3000,5000 tons / year
