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.production
Low activity of zinc oxide, high energy consumption and serious environmental pollution and material waste.My company's dynamic drying calcination process
Equipment, can produce highly active, high purity zinc oxide.Zinc oxide flash dry calcining stoves with energy saving, environmental pollution-free, back
High efficiency, covers an area of small, high degree of automation, etc.
 
Working principle:
By dynamic tail gas produced from burning furnace burning material into the, the dryer, the feeder will be 30 ~ water content
50% of the filter cake shape zinc carbonate into the dryer, the scattered dry powder of zinc carbonate into dynamic calcination furnace, by burning
Coal, natural gas or gas produced by hot air into the sintering furnace, with the charging of zinc carbonate in heat transfer and mixing
400 ~ 1000 ℃ hot air heating, zinc carbonate after a few seconds fast decomposition of zinc oxide, zinc oxide by the capture of the decomposed
Trap set into the bunker.
 
Performance characteristics:
1. Uniform decomposition temperature quickly, and can realize high active high purity zinc oxide production, activity > 80, 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%
 
Technical specifications:
Within the scope of the series model single sets of zinc oxide production was 1000, 2000, 3000, 5000 tons/year
