Calcium aluminate rotary kiln
2025-08-30
1. Working Principle
Ore Limestone and bauxite Enter the calcium aluminate rotary kiln, where fuel is ignited and burned by the rotary kiln burner for heating. The raw ore moves countercurrently with the hot gas flow inside the kiln. In the heating zone, the raw ore is heated to the reduction temperature and then enters the reduction zone. The flame center temperature in the reduction zone is controlled at 1000 around ℃, and the temperature of the reducing atmosphere in the reduction zone is controlled 700 around ℃ to react and reduce with the reducing gas. Then it enters the cooling zone, where it meets the incoming gas, which is preheated, and the ore is cooled and discharged outside the calcium aluminate rotary kiln. After water cooling by a continuous bucket conveyor, it is stored for selection.
2. Burner Selection
- Gas Burner
Fuel: natural gas, liquefied petroleum gas, blast furnace gas, coke oven gas, light hydrocarbon gas, etc.;
- Oil Burner
Fuel: diesel, methanol, heavy oil, alcohol-based fuels, etc.
- Pulverized Coal Burner
Fuel: pulverized coal
Currently, the most commonly used on the market is Natural Gas Burner 。
3. Applicable Industries
Environmental protection, sewage treatment, steel industry, calcium carbide industry, pulverized coal co-firing, etc.
