Centrifugal Feeder Patents (Class 209/915)
  • Patent number: 8083071
    Abstract: A classifier includes a central particle inlet, an inclined feed surface, and a classification surface. A plurality of particle feeding vanes are positioned above the feed surface, and the plurality of particle feeding vanes rotate above the feed surface. A plurality of classification vanes are positioned above the classification surface, and the plurality of classification vanes rotate above the classification surface. Particles enter the classifier through the inlet near an axis of rotation and flow radially outward on the feed surface to the classification surface.

  • Patent number: 8002117
    Abstract: A method and apparatus for sorting a gas-driven stream of generally flat and light-weight articles of varying dimensions execute a, preferably optical, inspection and upon so finding a non-conforming article remove the latter from the stream. In particular, the inspection and the sorting are executed during a substantially straight movement of the articles. The removing is executed through gas driving in a direction substantially transverse to the straight movement. Advantageously, the inspection is preceded by orienting the articles through a centrifugal force that orients said articles against an inclined wall in a transition to the vertical movement. Also airflow means (83,84) can be used to confine the articles in a thin layer.

  • Patent number: 7975852
    Abstract: Centrifugal device (1) of the rotating bowl type for supplying preforms (2b), which are horizontally-laid and aligned, from preforms (2a) received in bulk, comprising a rotating transport ring (3) delimited by a lateral guide (12) and a central rotary disc (6) in the same direction as the ring and with an axis (8) inclined relative to that of the ring; a mobile member (15) mounted on the lateral guide occupies, as a result of the actuating means (18), an operational position in which the preforms (2c) are forced to leave the ring; detection means (19) upstream of the mobile member detect an undesirable preform (2c) on the ring and control actuating means for bringing the mobile member into its operational position for the ejection of the undesirable preform.

  • Patent number: 7413084
    Abstract: The present invention is directed to a system and method for continuously or substantially continuously separating particulate matter based on particle size and/or density of the matter. The system includes a separation chamber having a bottom portion disposed within a cavity of a rotatable bowl having fluid therein, preferably water. The internal cavity of the separation chamber is maintained under negative pressure such that fluid is drawn through the separation chamber at a predetermined velocity to separate the solids. Larger, dewatered and/or denser solids are directed to the cavity of the rotatable bowl and can be removed by rotation of the bowl while the smaller and/or less dense solids and fluid travel up through the separation chamber.

  • Patent number: 7384503
    Abstract: A method and system for determining trace oversize contaminant particles in a paper-making pulp employs a screen assembly having a screen housing with a screen mounted therein, and ports for introduction of aqueous pulp and rinsing and flushing fluids, and for withdrawal of screened aqueous pulp, the screen housing has no port designated for the sole purpose of removing accumulated contaminant particles from the screen housing; instead the port employed for introduction of aqueous pulp and which may also be employed for introduction of rinsing fluid to the housing, is employed as the flushing port for removal of contaminant particles.

  • Publication number: 20040026301
    Abstract: The invention relates to the field of machines for directing and aligning plastic containers and particularly relates to an universal device for automatically adjusting vertically directing and aligning means in dependence on said containers size. The orienting means are formed by a plurality of cradles (5) and the aligning means are formed by a corresponding plurality of discharge channels (6), both means are provided with movable parts (10) and (35) respectively adjustable in dependence on plastic containers size. The device provides at least one control member (7) located on the machine outer stationary cylindrical wall (3) and adapted to engage movable parts (10) and (35) of cradles and discharge channels respectively while the inner hopper holding bulk plastic containers rotates.

  • Patent number: 4126226
    Abstract: The separator comprises a housing with a charging apparatus arranged above an apparatus for delivering and preparing the ore in a layer one grain thick. The apparatus for delivering is made as a bowl provided with a drive for rotation. Enveloping the bowl is a vertical partition dividing the interior of the housing into annular compartments for receiving the products of separation. Disposed above the bowl is a horizontal light-insulating partition on which X-ray tubes, photocells and air ejectors are mounted. The horizontal partition is formed with an opening to receive the charging apparatus and with slots for the passage of X-ray radiation, X-ray luminescence and air pulses.
