Abstract: This application concerns the separation of fine granular mixtures that may occur when the grains are suitably vibrated within fluid. In particular, the present invention provides a method of separating a particulate mixture comprising different particle types, comprising subjecting a supported particle bed comprising a fluid and said particulate mixture to a vibration thereby to effect separation of the particulate mixture into strata each of which is preferentially rich in substantially one particle type. Apparatus for effecting the above method also provided.

Abstract: A method of separating particulate material of differing size or density including the steps of: tumbling the particulate material to produce continuous or discrete avalanches (19) in the surface of the particulate material to move particles of smaller size (14) or higher density (22) towards the centre of the particulate material and particles of larger size (16) or lower density (24) radially outward from the centre of the particulate material; and extracting particles at selected radial locations (8, 10). A device for separating particulate material of differing size or density is also provided.

Abstract: An apparatus and method for the separation of husks and other chaff material apart from bird seed includes a smaller diameter inner container that is placed inside of a larger diameter outer container. A plurality of feet elevate the inner container above a floor of the outer container. A lid is used to cover the outer container and also the inner container. A housing is attached to the inside center of the lid and it includes a motor disposed distally from the lid with a fan blade attached thereto to displace air. A plurality of vanes are attached to the housing from which they extend until they contact the inside surface of the inner container. The vanes prevent a cyclonic air current pattern from occurring and so help to displace the husks apart from the seed. An offset mass introduces vibration which tends to raise more of the husks to the surface where they are displaced out from the inner container.

Abstract: A sluice box has an open box frame formed from a plurality of welded beams. A trough having an arcuate transverse cross section is suspended in an inclined fashion within the frame by a plurality of chains. A low end of the trough has an end wall with a central aperture which serves as a sand drain. A transversely extending water overflow drain channel is disposed adjacent the low end trough wall. The bottom of the trough is provided with a series of spaced transverse ridges. A variable speed motor having a rotary output shaft with an eccentric weight and a cooling fan is secured to a bottom exterior surface of the trough, adjacent the low end wall, and serves to vibrate the trough. A second variable speed motor is utilized in conjunction with a pitman wheel and arm for reciprocating the trough from side to side. A pair of arcuate levers are pivotally mounted to the frame on opposite sides of the trough.

Abstract: The two stage gravity method of concentration of fine dry materials makes use of the differences in the specific gravity of the materials by using principles fairly similar to those used in wet shaking table. The dry materials are loaded in a continuous series of troughs as they pass successively underneath a loading means as they travel conveyor belt like in a close circuit and, as they travel they are firstly submitted to a series of cyclic directed shaking motions transversal to the troughs and secondly, to a series of similar cyclic shaking motions parallel to the long axis of the troughs, the whole resulting in the production of a concentrate, and of middlings and waste which are unloaded in suitable receivers as the troughs turn downward in their conveyor belt like circuit.

The mix of materials are vibrationally conveyed in a first direction by a vibration feeder and a deflecting force in a second perpendicular direction is exerted on the non-magnetic metals by moving magnetic fields produced by a plurality of linear motors. The apparatus includes means for controlling the longitudinal tilt and the transverse inclination to optimize the separations achieved with different mixes of materials.

Abstract: Spherically-shaped rolling solids are separated from irregularly-shaped nonrolling solids on the upper surface of a conoidally-shaped rotating table whereon most of the spherically-shaped solids roll from the surface of the table and most of the nonrolling solids move circumferentially with the table until they contact a special scraper which deflects the nonrolling solids off the bottom edge of the table. The action of the table, the scraper, and the two combined, causes nonrolling solids to move downwardly, outwardly and circumferentially in a first path, then in a circumferential path, and then downwardly, outwardly and circumferentially in a second path, and off the bottom edge of the table. This movement of the irregularly-shaped solids frees trapped rolling solids and allows them to roll downwardly and outwardly off the table while the nonrolling solids continue to move circumferentially.

Abstract: Particles flowing in a stream can be arranged in an order of classification extending transversely of the stream according to physical characteristics of the particles by self-screening and stratification which occur in response to a continuous vibratory feeding of the particles in a direction laterally of the direction of flow of the stream. Particles having similar physical characteristics will flow from a specific portion of the stream into a collecting receptacle having a plurality of compartments arranged in a line transversely of the stream for separately collecting as many stream portions as required to obtain the desired degrees of separation. Further particle assortment from each stream portion can be made in accordance with the particles trajectory of fall from the stream bed.
