  • Patent number: 9616605
    Abstract: The invention pertains to a pellet mill 2 for forming pelleted material, the pellet mill 2 comprising: A die 4 having a cylindrical inner surface 6 with a plurality of apertures 8 formed therein and extending to the outside of the die 4, the volume bounded by said inner cylindrical surface 6 defining a die chamber 10. At least two cylindrical rollers 12, 14, 16 adapted to travel over said inner cylindrical surface 6 of the die 4 in a rolling motion. Drive means for causing relative rotation of the die 4 and the rollers 12, 14, 16, so that the rollers 12, 14, 16 will travel over the inner cylindrical surface 6 of the die 4, thereby forming wedge-shaped spaces 18, 20, 22 between the rollers 12, 14, 16 and the inner cylindrical surface 6 of the die 4.

  • Patent number: 8974710
    Abstract: The present invention provides a pellet mill (20) for preparing pellets from a pelletizable material supplied to the pellet mill (20), comprising a frame (22), a main axle (28) rotatably mounted in said frame (22) and having a first end (30) and an opposite second end (32), an annular die (42) being supported by said second end (32) and having an inner surface (44) for receiving a portion of said pelletizable material (106) supplied to said pellet mill (20), an outer surface (46), and a plurality of radial channels (48) extending from said inner surface (44) to said outer surface (46) for preparing pellets from said portion of said pelletizable material (106), a roller holder (54) supported by said frame (22), a number of roller axles (64), each of said number of roller axles being moveably mounted in said roller holder (54), said roller axles may move in said roller holder (54) in the event of an overload to prevent damage to the pellet mill, a number of rollers (80), each of said number of rollers being rot

  • Patent number: 8763606
    Abstract: 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.

  • Publication number: 20140138865
    Abstract: It is the object of the present invention to provide a method of controlling a pellet mill, said pellet mill comprising—a number of rollers (2,3,4),—a cylindrical die (1) provided with perforations, said rollers (2,3,4) being mounted inside said cylindrical die (1) for pressing material to be pelletized through said perforations,—an adjustment mechanism (5,6,7) for adjusting the distance between the rollers (2,3,4) and the die, (1)—a drive mechanism (M4) for rotationally driving said die (1) and said rollers (2,3,4), said method of controlling comprising the steps of—providing a measurement (8,9,10,11,12,13,14) of a parameter (x,y,z, W1,W2,W3,W4), said parameter indicating if an overload of the pellet mill is arising, and—in case of such indication being detected, reducing the load on the pellet mill by suitable counter-measures.
