The Loesche VRM has adaptable grinding modules which are already proven to be the way forward in other mining industries, allowing for variant mineral ores to be milled efficiently to the required particle size. The VRM, depending on the roller size, has a high reduction ratio; feed from 80 mm to 140 mm to a product of P80 at 75 µm in one pass ...

Vertical Roller Mill The vertical roller mill (VRM) shown in Figure 4 is an air swept, mediumspeed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulicallyloaded grinding pressure through three grin ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal

Abstract: As the Vertical Roller Mill (VRM) becomes more widely accepted for new cement grinding systems differences in installed costs between a VRM and a ball mill system are more frequently discussed. Past comparisons of total installation costs for a ball mill with high efficiency separator versus a VRM have indicated the higher equipment costs associated with the roller mill made it a ...
