Calcium aluminate rotary kiln is the equipment mainly for calcining cement clinker. Rotary kiln for calcium aluminate is widely used in cement, metallurgy, chemical industry, and other industries.
Calcium aluminate is a high-grade raw material for bauxite and limestone kiln. Calcium aluminate does not absorb water and chalk, it does not deteriorate during storage and transportation so does mineral composition and pre-melted aluminum and calcium.
Rotary kiln for calcium aluminate’s low melting point can quickly melt steel desulfurization. The rotary kiln for calcium aluminate is a premelted refining slag type in metallurgical building materials.
Kiln Operation Parameters
Rotary Kiln For Calcium Aluminate Characteristics
- Calcium aluminate rotary kiln has the characteristics of simple structure, reliable operation and easy control of the production process.
- Calcium aluminate rotary kiln can be widely used in various fields such as chemical industry, environmental protection, and sewage treatment.
- The new technology on calcium aluminate rotary kiln overcomes the high calorific value of the coke oven gas and the short flame combustion problem, which can make full use of the remaining coke oven gas.
- Calcium aluminate rotary kiln has very good energy saving, environmental protection and synergistic effects for small and medium-sized steel enterprises, coking enterprises, calcium carbide enterprises, and refractory industries.
Rotary Kiln For Calcium Aluminate Working Process
The original mine is directly fed into the tail of the calcium aluminum rotary kiln, which is delivered by the electronic belt meter, belt conveyor, belt conveyor, stabilizer and lock valve. First, the ore enters the calcium aluminate rotary kiln to be heated. The original mine in the kiln flows backward against the heat. In the heating area, the raw mine is heated to the reduction temperature and then be put into the reduction zone.
The temperature in the reduction zone is controlled at around 1000℃, and the temperature of the reduction area is controlled at 700℃ to create a reduction reaction with gas. Second, after the cooling zone, the core is cooled down then be ejected outside the kiln, and after the continuous bucket conveyor s’ water cooling, the ore is able to opt-in the storage.
