Calcium Aluminate Kiln
calcium aluminate rotary kiln is a kind of main device for processing kaolin. Meanwhile, it is also widely applied to metallurgy, chemical industry and building industry. Kaolin rotary kiln produced by our factory is characterized by firm structure, stable running and high finished products.
Application Range：widely applied to metallurgy, chemical industry and building industry.
Applicable Materials： ceramic sand, clay, yellow mud, river sludge, coal slurry, furnace slag, dolomite, bauxite, refractory material, limestone, active carbon, zinc oxide and special cement.
Simple structure, stable running and production
Calcium aluminate rotary kiln holds features of simple structure, stable running and stable production process
Wide application range
Can be widely applied to chemical industry, environmental protection and sludge treatment;
This new type rotary kiln overcomes many problems such as high thermal value of coke gas and short flame, which can make full use of residual coke gas.
Service life can last for 8 to 10 years. with good maintenance, it can be used for longer time.
With less quick-wear parts.
Important parts adopt advanced thermal processing technology. Replace period can reach 5000 hours.
More environment friendly
Adopts multi-class dust collecting method, clean exhaust gas emission can totally meet national standard.
Raw materials will be fed into kiln end through belt scale, belt coveyor, stability bunker, storage, air-lock valve. There is only stable material storage equipped at kiln end in order to reduce investment. After entering calcium aluminate rotary kiln, iron ore will be heated first. Raw ore will move towards in the opposite direction of hot air in kiln. In heating area, raw ore will be heated to certain temperature and enter to reduction area. The central temperature of flame should be controlled at about 1000 degree. The temperature of hot air in reduction area should be controlled at about 700 degree and react with reduced coal gas. After that, hot air will enter cooling area and meet with coal gas which will be preheated. After being cooled, mineral ore will be discharged out of the calcium aluminate rotary kiln. After being water cooled, materials will be sent to storage for being chosen.
