    OverviewBall MillsHistoryMaterials groundTemperature controlRoller millsHigh-pressure roll pressesCapacity of cement mills

    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

  • Factors Affecting Ball Mill Grinding Efficiency

    The most common of these is water, which displays a variety of effects on the grinding process, depending on the nature of the material and the percent solids of the mix. Dry grinding may require ten to fifty percent more power than wet, although this is offset by greatly diminshed media and liner consumption. The introduction of several percent moisture without heated gas sweeping can ...
