Operation and Elements of aClosed Circuit Ball Mill System.Cement ball mills typicallyhave twogrinding chambers. The first chamber is filled with largerdiameter grindingmedia and lined with lifting liners. The first chambercoarse-grindsthe feed material and prepares it for the second chamber. The second chamber is thefine grinding chamber.
