Energy saving is an important condition for the construction of a conservation-oriented society, to create a harmonious society, but also the most effective way to cement corporate profit growth. Energy conservation is to improve efficiency, but decided to increase the key grinding efficiency, is to reduce the moisture content of raw materials. Because fly ash, slag, etc. into the plant water is too large, is not conducive to grind the new lignite dryer, resulting in low yields grinding system, full grinding and grinding paste grinding deterioration in the working conditions phenomenon, you must first feed mill before baking dry dehydration. Therefore, fly ash produced dryer for the comprehensive utilization of fly ash to provide good prospects for development. The new fly ash dryer technology is the production of energy-yielding fly ash, slag powder and other critical equipment must be matched, in improving energy efficiency of cement, compared with centrifugal dewatering equipment, old vertical dryer, in design, energy savings and practical application has a significant breakthrough. Fly ash drying system works as follows: wet fly ash from the feeding device into the inner three-cylinder, to achieve downstream drying, fly ash in the inner constantly took a copy board, scattered spiral travels type heat exchange, and the other end to the inner movement of materials into the middle, countercurrent drying, the material is repeated constantly in the middle Yang Jin, was traveling way to step back two steps forward, both fully absorb the material in the middle inner cylinder the heat lignite dryer equipment, but also absorb heat the middle of the drum, while extending the drying time, the best material in this dry state. The other end of the line to the middle of material falling into the outer layer of lignite drying machine, material rectangular multi-loop mode of travel in the outer drum, to the drying effect of the material in the hot air exhaust fast marching drum role, did not meet due to the drying effect of the wet material weight but not fast marching, copy the material in this rectangular plate fully dry, so as to achieve drying effect, complete the drying process.
