  • Cement Kilns: Size Reduction and Grinding

    There is no doubt that this is just where the many kinds of edgerunner mills now largely used for grinding cement, fail to come up to the oldfashioned millstones, viz. in the flouring of the cement. They depend too much on their sieves: the clinker is passed under the runners and all cracked slightly, and then passed up to the

  • Finish Grinding Industrial Efficiency Technology & Measures

    In the finish grinding, clinker is mixed with gypsum and other minerals, such as blast furnace slag, according to the specifiions of desired end products and are ground, or milled, to achieve required particle fineness. Finish grinding accounts for nearly 40% of the electricity use in cement production. (ECRA, 2009)

    However, stirred mills can be applied to cement grinding if the feed size is made suitable. For example, instead of regrinding the separator reject in the tube mill, it can be directed to a stirred mill. Thus a possible energy saving can be obtained compared to ball mill grinding. Because, stirred mills are reported to supply

  • The cement mill Understanding Cement

    Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers,
