    A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis, imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel. The smaller grades are occasionally cylindrical ("pebs") rather than spherical. There exists a speed of rotation (the "critical speed") at which the contents of the mill would simply ride over the roof of the m

  • Grinding systems Fives in Cement Minerals

    The ball mill is traditionally the basic technology in a cement plant and is a very reliable machine. It is particularly well adapted to the grinding of products at high fineness, very abrasive products and solid fuels, as well as to a wide range of minerals.

    Cement Mill System. As part of a plant expansion, additional cement grinding system capacity was required. The client selected a vertical roller mill system to supply the additional capacity. The system includes belt conveyors, mill feed bins, weight feeders, a vertical roller mill, recirculation bucket elevator, fabric filters, fans, pneumatic

  • Optimization of Cement Grinding Operation in Ball Mills

    Optimization of The Cement Ball Mill OperationOperation and Elements of A Closed Circuit Ball Mill SystemAuditing The OperationResults of OptimizationCement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber. It is lined with classifying-type mill shell liners and provided with finer ball charge. Classifying liners ensure that the ball charge is segregated along the length of the chamber keeping larger grinding media at the beginning o
