1. The technical performance and running situation of rotary kiln, to a great extent, decide the quality, quantity and cost of Enterprise Products. If there is big kiln turning, there is a million. This folk rhyme is a vivid description of the importance of rotary kiln in production process.
2. As to the application of rotary kiln, the cement industry owns the most numerous rotary kilns in production. The whole cement process flow can be generalized as Two Whet A Burn. A burn refers to the process flow that calcining grinded raw materials to clinker under the high temperature of rotary kiln. So, rotary kiln is the host machine in cement production, it usually called as the heart of cement plant.
3. In building material industry, besides cement clinker, rotary kiln is also used to calcined clay, limestone, and drying slag; in the producing of fireproofing materials, raw materials calcined by rotary kiln has the features of stable size, increased strength, and easy to reshaping.
4. During ore beneficiation, rotary kiln can be used to magnetic roasting to the poor iron ore, which can change the weak magnetism into strong magnetism, so that it can be easy in magnetic separation.
5. In chemical industry, rotary kiln is used to produce soda, calcine phosphatic fertilizer and barium sulphide. In the 1960 s, the American Lapple invented the new technology to produce phosphoric acid with rotary kiln. This new technology has the advantages of low energy consumption, low electric power consumption, none sulfuric acid and can use low grade phosphorite.
6. For Environment Protection, it has a history for 20 years that the developed countries use cement kiln to calcine hazardous wastes and rubbish. This method can not only make the waste become less and harmless, but also can make waste as the fuel, which can save coal powder and realize the recycling of waste.
Among many production industries such as building material, metallurgy, chemical industry environmental protection, the widely used turning circle equipment which process solid material with mechanical, physical or chemical is called rotary kiln.
