  • Factors Affecting Ball Mill Grinding Efficiency

     · 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 virtually halt grinding of fine material, until increased water addition carries the material through the sticky stage into the normal wet grinding range …

  • Grinding Mills

     · Indian Minerology March 20, 2017. Grinding is the second step of mineral processing and the last stage of the comminution process. The product from a crushing unit is fed to a mill in order to decrease the particle size (sometimes even to 10 microns) for subsequent processing. The reduction ratio is usually large (8 to 25:1 sometimes 500:1).
