4、e economic benefits. New Fly Ash dryer - energy efficient, environmentally friendly.Chinas cement industry in recent years, a major breakthrough in comprehensive utilization of resources, waste cement industry consumptive use of solid waste in the country total more than 80%. By using less clinker c

5、ement industry, more powder, the cement produced in low-capital technologies that can maximize the consumption of electric power, metallurgy, coal industry produced fly ash, slag, coal gangue and other industrial waste. Our process uses traditional cement clinker produced, mixed material mixing mill

6、, mill production is low, high energy consumption, waste slag and other materials used only as a hybrid, mixing amount of not more than 30%. Use of clinker, slag grinding process, respectively, the use of slag fine powder in the high state of good activity can be used as the main component of cement

7、 characteristics, the preparation of blending of cement, admixture of 50% -60%, can substantially reduce the cement produced in the capital. Waste produced by the cement industry, based on a variety of waste powder admixture fair match to progress in concrete density, the formation of low density, h

55、 and other cost savings reached 35,470 euros. These sav in gs, comb ined with the in crease in annual out put of 57,600 euros, for a total of 93,070 euros.Because the central feeding system, and 4 sets of vacuum dryer total investment cost of 100,000 euros, the overall total cost savings sufficient
