Christian Pfeiffers ball-mills and internals like diaphragms, slotted and backside plates for diaphragms, mill shell In addition to the size and the grindability of the feed material the efficiency of a ball mill is mainly determined by the . The ball charge composition is coarser, i.e. balls of bigger size than in the second chamber are charged. To assure an efficient grinding, Christian Pfeiffer developed a classifying lining design which assures that the bigger ball Additional equipment.
