Rotary slime dryer drying stove is a major component of the device, which provides hot gas dryer heat required moisture drying material, a dryer can produce standard, the first consideration is whether the stove able to provide a stable high-quality high-temperature hot flue gas. Currently, the dryer heating system using domestic cement enterprises using artificial feeding of basic stove burner stove and mechanical spray roaster and coal stove. Artificial feeding hot ovens, their feeding, slag, flue gas temperature level completed by manual, labor-intensive, low thermal efficiency, pollution, temperature and difficult to control, not long-term pressure fire, life is short, the advantage of the investment low and simple maintenance. A little higher and more advanced machinery thermal efficiency of coal-fired furnace, but the higher the quality of the coal quality and size requirements for coal-fired, coal preparation process, high power consumption, coal mill wear, high maintenance cost, pollution, in can not be achieved on a combustion furnace desulfurization, and the big investment, now has less. There is also a fluidized bed furnace flue gas temperature is very stable, gravel machine prices can be controlled and machine control, low carbon content in the slag, slag, high activity, high-quality mixed materials, in line with the national energy policy, usually repair small, but a one-time investment is relatively large, is one of the new technologies to promote energy conservation. Xiang spray into mechanical grinding coal stove mainly dusting + flamethrower + hybrid burner consists of three parts. Flue gas temperature is very stable, self-control and manual control. The technological content of products to meet international standards, is one of the most advanced processing equipment, Cheng Xiang mechanical completion of the first production of this product research and development, in addition Henan region renowned quality impact crusher, Henan into Xiang is also very good.
