the grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. the comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the vertical roller mill has a rotary grinding table grinding rollers and a nozzle ring surrounding the table for providing an air stream to entrain ground material. downstream of each roller is a scraper with a nozzle for directing a blast of air onto the crushed material leaving the roller to break up the material so that finer fractions pass into the conveying air stream
having purchased the loesche state-of-the art vertical roller mill for the grinding of cement, cementos san marcos decided to supply another vrm for the grinding of coal.
