Bauxite calcination production line is a production line for producing bauxite clinker. Bauxite clinker is an important industrial raw material, widely used in metallurgy, chemical industry, building materials and other fields. The bauxite reburning production line mainly includes raw material crushing, screening, calcination, cooling, flue gas treatment and other processes.
The raw material of the bauxite calcination production line is bauxite ore. The bauxite ore entering the factory must first be crushed and screened, and the bauxite ore of various particle sizes must be processed into materials with a certain particle size range, and then enter the rotary kiln for reburning. The crusher generally uses a jaw crusher, and the screening machine generally uses a vibrating screen. The screened material enters the rotary kiln for calcination, and the screened material is sent to the grinding system. The screened material is ground into powder and granulated, and then enters the rotary kiln for calcination. The rotary kiln is the core equipment of the bauxite reburning production line. The bauxite ore is constantly rolling in the rotary kiln, and the hot flue gas generated by the fuel sprayed by the burner is continuously heat exchanged to gradually generate bauxite clinker. The main purpose of calcination is to remove moisture and volatile impurities from bauxite ore, and to undergo physical and chemical reactions at high temperatures to form clinker with a certain structure and strength. Factors such as calcination temperature, calcination time and atmosphere have a great influence on the quality of clinker. The temperature of the calcined bauxite clinker is high, and it is cooled in a single-drum cooler and then discharged to the clinker yard. The bauxite reburning production line will generate a lot of dust and exhaust gas during the production process, which will pollute the environment. Therefore, the production line needs to be equipped with corresponding environmental protection facilities, such as dust collectors, desulfurization devices and denitrification devices, to reduce pollutant emissions and protect the ecological environment.
