Raw balls are usually ground by rolling under pressure between a cast iron disc (rill plate) and a vitrifi ed grinding wheel. The grit size of the abrasive depends on the dimension of the balls and process requirements. In general, smaller balls require fi ner grit and harder grade, larger diameter balls require coarser grit and softer grade.
The grinding roller is jointed with pressure frame by Roller pin, it can sway between 12-15degree,so the roller can adapt to the thickness of material, input size and the wear of roller well. Because of uniform wear and load, the vibration is less and has strong ability to resistance stone, wood and iron.
By using a roller mill, or adopting roller grinding principles as part of the feed mechanism on entry to the hammermill, the raw material is partially ground at that point, which then allows the hammers and screens in the grinding chamber of the hammermill to be fully effective, with often excellent grinding efficiency results.
