    A cement mill (or finish mill in North American usage ) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

    Limestone addition considerably influences some characteristics of cement, but this influence depends also on other factors. By the use of an experimental design technique, synergistic effects of Limestone addition considerably influences some characteristics of cement, but this influence depends also on other factors. By the use of an experimental design technique, synergistic effects of limestone addition, fineness and clinker type were detected. The effect of limestone addition depended more on clinker type than on its fineness.Cited by: 159
