Over the last three decades the vertical roller mill has become the preferred 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,Web

In short, rollers with vertical stripes are better in structural stability and wear resistance than rollers with horizontal stripes. Shown as the figure 18, the wearing depth of the vertical stripe roller whose depth-to-width ratio has been improved through golden section method shows a downward trend. When the depth-to-width ratio is 0.382 ...Web
