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 It is also faster to install than a traditional ball mill significantly reducing initial costs Lower operating cost Vertimill is an energy efficient grinding machine They tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns
