The difference between ball mill and vertical mill in cement grinding
Over the last three decades the vertical roller mill has become the preferred ball mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the An interesting historical fact is that a vertical roller mill uses the same operating principle as the pistrium or pistrinum, an antique Roman grain mill.The largest grain mills used worked aChapter Six: Some Operating Guidelines Vertical Roller Mill
