Vertical Roller Mill To Works 9 10

The grinding efficiency can be improved by use of a vertical roller mill, while reducing the energy consumption and improving the product quality.The disclosed cement clinker grinding apparatus comprises a closed circuit for conveying the ground material from the vertical roller mill (21) to the external separator (28) by the bucket elevator (29), for classifying the conveyed material into coarse powder and fine powder, and further for returning the classified coarse powder into the vertical roller mill (21).That is, a part of the ground material conveyed by the bucket elevator (29) is divided by the distributing damper (32) and then directly returned to the vertical roller mill (21).Since the ground material are not conveyed by air flow conveyance (i.E., air sweep), it is possible to prevent an increase of power consumption of the suction fan (31).Further, since a part of the ground material is distributed by the distributing damper and then further ground again by the vertical roller mill, it is possible to obtain an optimum particle size distribution of the cement products, so that the cement quality can be improved.Vertical roller mill is a new kind of large scale power mill which is designedspecially to solve the problems of low capacity and high consumption ofindustry mills.With a decade of years research of mills, verticalroller mill is designed and manufactured based on our advanced designidea, and in combination with the european technology and the marketdemand.It adopts reliable structure and reasonable process flow,integrated with drying ,milling, classifier , elevator.Especially ,itcan fully meets the requirement of clients in the high production ofpowder and its main technical and economy indicator reaches theinternational level.Application: specialized for the high production of superfine pyrophyllite powder making in glass fiber industry; specialized for the high production of gangue powder making in coal industry; specialized for the high production of various of chemical raw material powder making in the chemical industry.Application: specialized for the high production of superfine pyrophyllite powder making in glass fiber industry specialized for the high production of gangue powder making in coal industry specialized for the high production of various of chemical raw material powder making in the chemical industry.It is a necessary equipment for the high production of mineral powderin the non-mental mine industry and large scale powder making in manyother industries.Technical data of vertical roller mill: specificationcapacity(t/h)humidity of raw coalfineness of powderhumidity of powder(%)motor powerkw.
