  • The cement mill

    Grinding systems are either open circuit or closed circuit. In an open circuit system the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system coarse particles are separated from the finer product and returned for further grinding.

  • Grinding Millan overview ScienceDirect Topics

    The first step in slag processing is size reduction to liberate metallic iron and iron-bearing minerals. This is done by crushers or by autogenous grinding that is the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80 Fe (Shen and Forssberg 2003).
