The invention pertains to a pellet millfor forming pelleted material, the pellet millcomprising: A diehaving a cylindrical inner surfacewith a plurality of aperturesformed therein and extending to the outside of the die, the volume bounded by said inner cylindrical surfacedefining a die chamber. At least two cylindrical rollersadapted to travel over said inner cylindrical surfaceof the diein a rolling motion. Drive means for causing relative rotation of the dieand the rollers, so that the rollerswill travel over the inner cylindrical surfaceof the die, thereby forming wedge-shaped spacesbetween the rollersand the inner cylindrical surfaceof the die. A feed system, comprising at least two conduits, one associated with each of the at least two rollers, extending into the die chamber, each of the conduitshaving a side openingfor feeding the pelletizable materialinto the wedge-shaped spacesbetween the rollersand the inner cylindrical surfaceof the die, the side openingextending axially along the conduitand having an extension that is equal to the length of the rollers, wherein at least one of the conduitsis configured for feeding the pelletizable materialdirectly to a wedge-shaped space, which is at a higher location in the die chamber than said conduit

Pellet mill with an improved feed system and a method of forming pelleted material

The present invention provides a pellet mill () for preparing pellets from a pelletizable material supplied to the pellet mill (), comprising a frame (), a main axle () rotatably mounted in said frame () and having a first end () and an opposite second end (), an annular die () being supported by said second end () and having an inner surface () for receiving a portion of said pelletizable material () supplied to said pellet mill (), an outer surface (), and a plurality of radial channels () extending from said inner surface () to said outer surface () for preparing pellets from said portion of said pelletizable material (), a roller holder () supported by said frame (), a number of roller axles (), each of said number of roller axles being moveably mounted in said roller holder (), said roller axles may move in said roller holder () in the event of an overload to prevent damage to the pellet mill, a number of rollers (), each of said number of rollers being rotatable around a corresponding one of said number of roller axles (), each of said number of rollers () being adapted to press said portion of pelletizable material () against said inner surface () for rolling, in response to rotation of said annular die (), along said inner surface () of said annular die () for forcing said portion of said pelletizable material () from said inner surface () to said outer surface () through at least one of said plurality of radial channels () for preparing said pellets, and a number of actuators (), each of said number of actuators () being operatively connected to a corresponding one of said number of roller axles () and being adapted to prevent movement of said corresponding one of said number of roller axles () relative to said die holder () for maintaining a distance between a corresponding one of said number of rollers () and said inner surface () of said annular die ().

Pellet mill having improved construction

The present disclosure provides an inhaler having a vibration element for aerosolizing medicament contained in a blister pack, wherein a plurality of individual blister packs are arranged in a rotary cassette that fits within a housing, and wherein the individual blister packs are dragged up into a clamping position between the vibration element and a piercing element. The motion of the blister pack is controlled by a rotary disk within the housing which further coordinates the movement of the piercing and vibrating elements for the piercing and deaggregation, respectively, of the individual blister packs.
