Cement grinding system mainly includes the four parts: raw meal grinding and coal grinding, grinding clinker and slag grinding grinding, has been, cement plants, the production of grinding by ball mill, high energy consumption and high pollution become endemic in many cement plants. With the development of industrial production technology, the new type of environmental protection, energy saving and high efficiency of the vertical roller mill is gradually introduced to promote the domestic cement plant. Xinxiang Great Wall Machinery Company decades working in cement vertical mill, coal vertical mill, slag vertical grinding, raw materials vertical grinding of R & D and production, technology maturity, has the hundreds of cement plants, steel mills, grinding station provides high performance vertical grinding equipment.
Comparison of noise and noise of vertical roller mill:
Ball mill noise pollution levels in general in more than 100 dB, and vertical roller mill out of the noise level is much lower than that of ball mill, generally within the range of 80 to 85 dB, good control of noise pollution.
Dust and dust pollution in vertical roller mill:
Ball mill in the production process inevitably produces a lot of dust, standing mill is set crushing, drying, grinding, grading conveying in one of the large grinding ideal equipment, with fully enclosed design, greatly reduce the dust emissions.
Cement vertical mill noise and dust pollution is much lower than that of ball mill has obvious now, not only that, vertical roller mill also overcome the flaws in ball mill grinding mechanism, has the advantages of high grinding efficiency, low power consumption (than that of ball mill energy saving 20% to 30%), high drying capacity, allowed into the grinding of large size materials, grinding process is simple, covers an area of small, low construction cost, wear small, long life and other advantages, he will be greatly reduced power consumption costs, operating costs, the latter wear-resistant parts costs, construction costs etc.. If the cement plant in Hubei can be replaced by vertical mill, the result may be a big reversal.
