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 vertical roller mill ...

WhatsApp: +86 18838072829The vertical roller mill is a kind of grinding machine for cement, raw material, cement clinker, slag and coal slag. It has the benefits of simple structure and low cost of manufacture and use. Vertical roller mills have many different forms, but they work basically the same. All of these forms come with a roller (or the equivalent of roller ...
WhatsApp: +86 18838072829distribution according to RRSB, cements from ball mills generally have a rather low slope [n']. In a VRM the grinding takes place by pressure and shear force. The clinker passes within seconds between the roller and the table. The energy input into the material during one passage between the grinding rollers and grinding track is relatively low.
