In the airswept mode, the verticalrollermill and a high efficiency dynamic classifier are suited above each other as a single unit (Fig. 1). Material is fed to the grinding chamber and transported by table rotation to the grinding gap between the fixed grinding rollers and the mill table. Crushing and grinding take place by compressive grinding.
