A planetary roller mill for processing a feed material includes a vessel with a grinding ring having an opening therethrough and a first area. The grinding ring is in sealing engagement with the inside surface of the vessel assembly. At least two non-circular support plates are secured to a rotatable shaft. Each plate has an axially facing surface. A plurality of rollers rotatably are 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 which configure 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 grinding assembly.

A hammeris provided for a material size-reducing machine of the type including a rotor on which the hammer is individually pivotally mounted. The hammerincludes a mounting endhaving a throughbore for receiving a pivot pin therethrough in connection with the pivot mounting of the hammer on the rotor, an extending portionwith the center of mass CGM located therein. The extending portion has a non-linear body portionand a linear body portionwith the linear body portionbeing inclined in a direction opposite to the rotation direction at an angle between 5 to 45 degrees as measured relative to a line RFL extending through the center of the pivot pin and the center of mass CGM of the hammer.

A high efficiency bowl mill () is provided by the present invention. Included in the high efficiency bowl mill () is a plow () that is downstream of a grinding roll () on a grinding surface (). The plow () loosens material that has been compacted by the grinding roll (). Also included is a deflector () that redirects an air stream so as to pick up material loosened by the plow () and deposit material requiring further grinding. An outlet () of an inverted cone () is positioned so as to deposit material for pulverization on the grinding surface () and to restrict the air stream from entering the inverted cone ().
