Abstract

A planetary roller mill for processing a feed material includes a vessel with a grinding ring having an opening and a first area. The grinding ring is in sealing engagement with an inside surface of the vessel. At least two non-circular support plates are secured to a rotatable shaft. Each plate has an axially facing surface. A plurality of rollers are rotatably mounted to and positioned between the two support plates. Each of the plurality of rollers are in grinding communication with the grinding surface. The planetary roller mill includes an air supply system having an outlet in communication with the opening in the grinding ring. Areas of the two support plates are of magnitudes configuring a flow area through the opening of at least 30 percent of the first area to provide a predetermined quantity of heated air to remove moisture from the feed material in the mill.
