CALCIUM ALUMINATE ROTARY KILN For Sale

Calcium Aluminate Rotary Kiln

Calcium aluminate rotary kiln is a kind of large-scale industrial equipment used for high-temperature calcination of calcium aluminate materials, which is also the main equipment for calcining cement clinker. Calcium aluminate rotary kiln is widely used in cement, refractory preparation, metallurgy, chemical industry, environmental protection field (such as water treatment agent production) and other industries, with high efficiency and energy saving, strong adaptability of raw materials, product stability and so on, it is the key production equipment in metallurgy, building materials and environmental protection field.

Calcium Aluminate is a compound with Aluminum Oxide (Al₂O₃) and Calcium Oxide (CaO) as the main components, it is a high-grade raw material for bauxite and limestone kiln, it has a high melting point, corrosion resistance, and excellent water-hardness, which can significantly improve the early strength of the material, high temperature resistance, and the efficiency of water treatment.

Calcium Aluminate Rotary Kiln Principle

The working principle of calcium aluminate rotary kiln is to generate calcium aluminate by chemical reaction between bauxite and limestone through high temperature calcination. The material enters the inclined rotating cylinder from the end of the kiln, gradually moves to the kiln head under the action of kiln rotation and gravity, and passes through the preheating zone (dewatering and decomposition), the calcining zone (formation of the mineral phase of calcium aluminate) and the cooling zone in turn, with the burner providing a high-temperature heat source at the kiln head, and finally obtains the sintered calcium aluminate clinker. The whole process realizes continuous production, and the reaction is fully carried out by controlling the speed, temperature and residence time.

Calcium Aluminate Rotary Kiln Advantages

• Calcium aluminate rotary kiln bit product heat consumption is as low as 800-1200 kcal/kg, which is 15% energy-saving than vertical kiln, and it has the characteristics of simple structure, energy-saving and high efficiency, reliable operation, easy to control the production process, and so on.
• Calcium aluminate rotary kiln is equipped with electrostatic dust removal, desulfurization tower, automatic control, and can be operated 24 hours a day. It is widely used in many fields such as chemical industry, environmental protection, sewage treatment and so on.
• Calcium aluminate rotary kiln refractory lining can withstand high temperature of more than 1500℃, overcoming the problem of high calorific value of coke oven gas and short combustion flame, and can make full use of the remaining coke oven gas.
• Calcium aluminate rotary kiln preheater recovers waste heat from exhaust gas and reduces energy consumption by 20-30%. The life of the cylinder is more than 10 years, and the replacement cycle of refractory lining is generally 2-3 years. It has a good effect of energy saving, environmental protection and efficiency enhancement for small and medium-sized iron and steel enterprises, coking enterprises, calcium carbide enterprises and refractory material industry.
