  • Cement Milling - Understanding Cement
    Cement Milling - Understanding Cement

    Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ( grindability ) is not always easy to predict, but large clusters of belite due to coarse silica in the feed

    The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time delay characteristics also dynamics changes within 2-4 minutes. The fast dynamics necessitate closer attention to

    6. Cement milling Finish milling is the grinding together of clinker with some 3-5 per cent gypsum, natural or synthetic, for set control, and quite often other components: blastfurnace slag, pozzolan, silica fume, limestone or pulverised fuel ash (‘pfa’ – also known as ‘fly ash’). The process and equipment circuits are similar to those

    Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation . The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved
