Abstract: A device and method for drying fine particulate. A parallel flow rotary drum dryer is used to dry the particulate material. There is a combustion chamber for the burner, located upstream of the dryer inlet, and the burner flame is limited to the combustion chamber so the fine particulate material does not come into direct contact with the burner flame. The output from the dryer passes through a knock-out box including a baffle system with a plurality of narrow gaps to create a pressure drop to slow down the gas flow and enable the entrained fine mesh dry particulate to drop out through a bottom outlet before the effluent gas is sent to the dust collection/air filtration system.

Abstract: A counterflow rotary cooler including an elongated rotary vessel having first and second ends, at least one inner tube nested inside one outer tube and defining an annulus space between said inner and outer tubes, with cooling water flowing from said first end to said second end through said annulus and then returning to said first end through the inner tube.

Abstract: An apparatus includes a separation deck free of stepwise changes in elevation between a first end and a second end, the separation deck comprising a plurality of spaces through which a constituent material may pass, a plurality of scrubbers disposed on the deck, the plurality of scrubbers having a first end disposed at a higher elevation than the deck in at least a first state, and a vibratory generator coupled to the deck. The mixed material moves over the deck and the scrubbers from the first end to the second end by the motion imparted by the vibratory generator. Components of the mixed material move relative to each other as the components move over the scrubbers, thereby causing the constituents material attached to the components of the mixed material to separate and pass through the spaces in the separation deck.

Abstract: A vibratory apparatus for separating a liquid from a liquid-laden solid material includes a trough having a base, a deck attached to the trough, and a vibratory drive attached to the trough. The deck includes a plurality of support members extending longitudinally along the trough, each support member having a solid wall surface with an upwardly oriented apex defining a support point and two edges disposed on opposite sides of the upwardly oriented apex, the apexes being spaced from one another by a distance sufficient to support the solid material above the base, the edges of adjacent support members being spaced to define a passage therebetween, and the apexes being located at an elevation sufficiently above the base to allow liquid to drain from the solid material and flow through the passage to the base.

Abstract: A conveyor may include a conveyor includes a frame, a trough supported on the frame, and a vibratory generator operatively coupled to the trough. The trough has a trough wall with a first plurality of apertures, and a plurality of baffles are spaced above the first plurality of apertures in the trough wall, the baffles defining a second plurality of apertures through which air exiting the first plurality of apertures may pass.

Abstract: In order to provide a leak-proof coupling for a gas-carrying pipe having two pipe sections that are relatively movable, the coupling includes a first pipe section and a second pipe section that have respective coupling ends disposed in closely spaced adjacent relation to define a gap therebetween. The first pipe section has an upstream end in communication with a source of a pressurized gas and a first coupling end remote therefrom such that the upstream end receives the pressurized gas from the source and the gas then flows through the first pipe section from the upstream end to the first coupling end for discharge therefrom. The second pipe section has a second coupling end in communication with the first coupling end and receives the pressurized gas from the first pipe section and the gas then flows through the second pipe section from the second coupling end to the downstream end for discharge therefrom.

Abstract: The invention relates to a structure for controllably discharging articles that are being continuously transported by a primary conveying structure. A discharge assembly is provided having a chute with an inlet and an outlet. Articles are diverted away from the primary conveying structure and delivered to the chute inlet. The discharge chute is mounted for rotation about a vertical axis and structure is provided for reciprocatively moving the chute outlet back and forth over an infeed portion of a secondary conveying structure to evenly distribute material in a serpentine path along the length of the infeed portion of the secondary conveying structure. In a preferred form, the secondary conveying structure has an associated trough for containing a cooling fluid.
