What are the advantages of rotary kiln and similar products?
1. In the building materials industry, inaddition to calcined cement clinker, rotary kiln is also used for calciningclay, limestone and slag drying; in the production of refractory materials,rotary kiln calcined raw materials are used to make the dimensional stabilityand strength increase and re-formed.
2. Its technical performance and operationdetermine the quality, output and cost of the company's products to a largeextent. "As long as the big kiln turns, there are tens of millions."
3. During the beneficiation process, thelean kiln is used to magnetize the lean iron ore to change the original weakmagnetic properties of the ore to strong magnetic properties to facilitatemagnetic separation.
4. In the chemical industry, the rotarykiln is used to produce soda, calcined phosphate fertilizer, and strontiumsulfide. In the 1960s, LapPle et al. invented a new process for producingphosphoric acid from rotary kiln. The method has the advantages of low energyconsumption, low power consumption, no use of sulfuric acid and availability ofmedium and low grade phosphate rock.
5. The whole production process of cementplant is summarized as “two grinding and one burning”, in which “one burning”is the process of burning raw materials prepared by grinding and burning intoclinker under the high temperature of rotary kiln. Therefore, the rotary kilnis the main engine in the production of cement, commonly known as the"heart" of the cement factory.
6. In terms of environmental protection,developed countries in the world have used cement kiln to burn hazardous wasteand garbage for more than 20 years. This not only reduces waste and harmlesswaste, but also uses waste as fuel to save coal powder and recycling of waste.
