Abstract: Screen for separating solid residues, and in particular for separating sheet or expanded material, such as bags or parts of bags made of plastic, polystyrene, spongy material or another light material, which comprises a separation station (10) interposed between the inlet port (P1) and the outlet port (P2) of the screen above its screening surface (P) and preferably after the powders and the lightest portions have already been separated. The station (10) comprises a hood (11) delimiting a suction chamber (13), and insufflation means (15) for orienting at least one lifting air flow (16) in the suction chamber (13) at the screening surface (P). The lifting air flow (16) is oriented for forming a vortex (17) confined in said suction chamber (13) and with rotation axis (Z) orthogonal to the screening surface (P) capable of lifting the sheet material and delivering it to suction means (18) associated with the hood (11).

Abstract: A method for removing a particulate contaminant material from a particulate mixed lithium metal phosphate material is provided. The method includes feeding the particulate mixed lithium metal phosphate material into a fluidizing stage containing particulate mixed lithium metal phosphate material of mass m, feeding the fluidized particulate mixed lithium metal phosphate material through a sifting stage, discontinuing the feed of the particulate mixed lithium metal phosphate material into the fluidizing stage after 10 to 100 times of the mass m have been fed into the fluidizing stage, fluidizing and sifting the material present in the fluidizing stage after discontinuing the feed until the mass of the material present in the fluidizing stage becomes 10% to 100% of the mass m, and removing the remaining material from the fluidizing stage.

Abstract: A dispenser feeds tablets from a storing section to a packaging section. A tablet-adhered powder removal device is provided in a preparation section between the storing section and the packaging section. The preparation section has rotating open-top receiving portions, and the tablets for one package are fed to each receiving section. One side wall of each receiving section includes a fixed plate having a groove-ridge portion, while the opposite side wall includes a swing plate. The swing plate vibrates when a cam roller rides on protrusions during the rotation of the receiving portion. Due to the vibration, the powder adhered to the tablets between the plates is stripped and removed. The powder falls from a gap formed by opening the plates, and is discharged to the outside. When the cam roller rides on a cam, the swing plate is swung and drops the tablets in the receiving portion.

Abstract: The invention relates to an apparatus for sifting feedstock, comprising: a. a static sifter that has a ventilated bottom which is oriented at an angle to the vertical and is penetrated by sifting gas; b. an inlet for feeding the feedstock to the ventilated bottom; c. an outlet for the coarse material; d. a dynamic sifter that is mounted downstream and encompasses at least one rotor with rotor blades and a horizontal rotor axis; e. at least one outlet for the sifting gas loaded with fine material; and f. a housing inside which the static and the dynamic sifter are arranged. The housing area surrounding the dynamic sifter is designed as a housing spiral such that the sifting gas flows against the rotor in a substantially tangential direction. The rotor rotates counter to the direction of flow of the sifting gas in the housing spiral.

Abstract: An arrangement used for filtering out conveying air when supplying fiber material to a processing machine is provided. The arrangement has an essentially vertical filling chute for the fiber material, the chute having an upper intake opening and a lower exit opening, a device with pneumatic fiber feed at the upper intake opening, and a floccule-forming device at the lower exit opening including a system of draw-in rolls and a fast-rotating opening roll. The chute includes at least one air-permeable surface for separating the fiber material from the conveying air. An evacuating device evacuates the filtered out conveying air. An exhaust air device is coupled to the evacuating device and has an air stream regulator which is connected to a control and regulating device. The conveying air stream is guided along the opening roll, and a partial air stream of the filtered out conveying air is guided into the exhaust air device.

Abstract: An air material separator may be used to separate scrap from a conveying air flow while having a relatively low weight and short height so that the separator may be positioned within today's single-story manufacturing or processing facilities. The air material separator of the invention includes a generally cylindrical inlet chamber having a spiral wall that directs the inlet flow circumferentially and downwardly. An outlet chamber is positioned below the inlet chamber and includes a conical, perforated wall that allows the conveying air flow to escape through the perforated wall. The scrap carried by the conveying air flow cannot pass through the perforated wall and moves down and out an outlet at the bottom of the conical wall. The overall height of the device is substantially less than prior art air material separators.

Abstract: A separating system for separating material transported by air utilizing apparatus having a tangential inlet for a stream of air and entrained material, a bottom material exit, a boundary wall air exit and a central interior air exit. Each air exit includes a perforated wall or screen through which air is removed or separated from the entrained material. Enhanced separating action is achieved through coupling two such separators in a loop arrangement such that the material discharge from a first separator is conveyed via a relay stream of air to serve as the input to a second separator, while the entire air exhaust from the second separator is returned as one of a plurality of inlet streams to the first separator. A further advantage is realized by partitioning the air exhaust of the first separator into a plurality of parallel passageways which can be individually closed.

Abstract: A method and apparatus for separating material transported by air is disclosed which includes a separator casing having a tangential inlet adapted to receive a stream of air and entrained material and a plurality of exits. One of the exits of the disclosed separator is a material discharge exit which, like the inlet is peripherally attached to the casing. There are also two separate air exits including a first air exhaust conduit peripherally attached to the casing proximate the inlet and a second air exhaust conduit centrally disposed within the interior of the casing. Operatively associated with each of the air exits is a separator means, such as a perforated surface or screen, which removes or separates the entrained material from the air.

Abstract: An improved method of recovering recyclable materials from commingled recyclables is described as well as apparatuses for doing same. Ferrous materials recovery is achieved using the unique combination of a magnetic belt and a vibratory conveyor. Other materials are then separated with a light/heavy separator which uses finger screen, air knife, and vibratory means to separate glass from plastics and aluminum prior to conventional handsorting operations. Excess glass unsuitable for recovery is introduced into a trommel processing loop wherein contaminates are removed and the glass reduced to a particulate useful in the production of glasphalt and aggregate. Air emanating from the air knife is filtered in an improved gravity separator for reintroduction to the light/heavy separator.

Abstract: A rubber tire component reclamation technique which provides tire rubber fragments classified according to size. Preferred apparatus for rubber tire component reclamation includes a feed hopper for receiving pieces of discarded tires, a granulating chamber coupled to the feed hopper for cutting the received pieces into smaller fragments, and an exit chute providing an output from the granulating chamber through which tire fragments fall. An air flow is induced upwardly through the exit chute to urge the less dense components such as yarn and fabric upwardly against gravity and out of the upper portion of the chute. The air flow is of sufficient force to prevent commingling and compaction of the less dense components with the remaining components of the tire fragments. A magnetized drum is located near the lower end of the exit chute for segregating the ferromagnetic components of the tire fragments.

Abstract: A catalyst loading hopper suitable for positioning in vertical position above a reactor vessel, having an inlet at its upper end, a catalyst outlet at its lower end and a diagonally-disposed baffle extending downwardly across the hopper but terminating short of one of the walls of the hopper and a weir adjustably arranged so as to control the flow of catalysts through the hopper. There is a dust outlet at the top of the hopper, which may be connected to a conduit so as to draw dust away from the upper end of the hopper and a screen at the bottom of the hopper to separate the catalyst from any fines or undersized catalyst particles. The screen feeds into a catalyst outlet which, in turn, feeds into a conduit, which extends into the reactor vessel so as to allow arrangement of the cleaned catalyst pellets in layers in the vessel. A gas nozzle opens in the wall of the hopper and allows dust to be blown from the catalyst pellets and through the dust outlet to be collected in a suitable filter.

Abstract: Self-cleaning separator apparatus is used in combination with a vertical settling chamber for extracting fiber product from a moving air stream. The separator apparatus includes a housing forming an air stream inlet, a product discharge outlet and a clean air outlet. A rotatable screen is interposed between the air stream inlet and the clean air outlet for collecting the fiber product on the screen as the air stream flows through the screen for discharge into the atmosphere. An air flow gradient is induced in the settling chamber whereby the air flow rate through the rotating screen is substantially smaller near the bottom of the settling chamber than it is near the top of the settling chamber. The gradient is produced in part by a transversely extending baffle plate mounted in the annular flow region near the product discharge outlet, and in part by the off-center placement of the rotary screen closely adjacent the sidewalls of the settling chamber which converge toward the product discharge outlet.
