  • Patent number: 9731327
    Abstract: A device for sorting objects includes an input conveyor device with a plurality of input storage devices, which are movable in an input conveying direction. A loading station loads each input storage device with one object. An output conveyor device has a plurality of output storage devices, which are movable in an output conveying direction. A sorting end point discharges the objects. A first transfer region, in which the input conveyor device and the output conveyor device are arranged, allows objects to be transferred from the input storage devices into the output storage devices. A second transfer region, separate from the first transfer region, in which the output conveyor device and the sorting end point are arranged transfers objects from the output storage devices to the sorting end point. An additional sorting end point in the second transfer region enables more flexibly operation of the sorting device.

  • Publication number: 20090134073
    Abstract: The invention relates to a method and a device for screening first particles out of a granulate comprised of first and second particles by conveying the granulate along a first screen surface which extends outward from a vibrating device, wherein the first particles have an aspect ratio a1, with a1>3:1, and the dimensions of the second particles allow them to fall through the mesh of the first screen surface.

  • Publication number: 20080314804
    Abstract: A vibratory screening machine includes a primary screening area and a pre-screening assembly including a frame and screen assemblies. The screen assemblies are secured to the frame and form a pre-screening surface. The frame is attached to the vibratory screening machine such that the concave pre-screening surface is above the primary screening area.

  • Patent number: 7343827
    Abstract: A method of detecting breaks in a porous element in a material separator is disclosed. A shielding is created in the material separator to form a barrier to RF energy. The shielding is formed with a path through the barrier capable of allowing RF energy and material to flow therethrough. The electrically conductive porous element is positioned fully across the path. An RF signal is transmitted on one side of the porous element, and signal levels of the RF signal are detected on the other side of the porous element, such that the detected RF signal crosses the porous element. A baseline signal strength indicator is established from the detected signal levels using an unbroken porous element. An operative signal strength indicator is generated from the detected signal levels. Breaks in the porous element are detected by comparing the operative signal strength indicator against the baseline signal strength indicator.

  • Publication number: 20040040895
    Abstract: A plansifter for separating the products of cereal milling, which includes a plurality of compartments arranged vertically, a plurality of sieves stacked in each compartment, a rotating mass assembly to keep under vibration the plurality of compartments and therefore the plurality of sieves, and flexible suspension assemblies to allow vibration. The plurality of compartments has a binary configuration, forming pairs of compartments that are symmetrical and aligned with respect to the rotating mass assembly that is arranged centrally. The plansifter allows a reduced footprint for an equal performance, allows to provide a modular construction that can be extended according to future requirements, to simplify mechanical construction and maintenance, and to distribute the flexible suspension assemblies according to requirements.

  • Patent number: 5190162
    Abstract: A machine for sorting packages having individual bar code identifications. The packages are received at an induction station and an induction conveyor moves the packages up to a gate which is driven by an actuator to allow individual packages to pass through the gate at predetermined intervals. The packages are driven by a transport mechanism along a slider bed having trap doors moveable between an elevated position in alignment with the slider bed and a lowered position providing openings in the slider bed for the packages to fall from the slider bed. The transport mechanism includes individual pushers to move over the slider bed spaced from one another by the predetermined interval so that each pusher receives a respective one of the packages from the induction conveyor and pushes that package along the slider bed.

  • Patent number: 4955482
    Abstract: In carbon-in-pulp (CIP) and carbon-in-leach (CIL) processes, especially those utilizing pure oxygen instead of normal air to increase the overall efficiency of the cyanide leaching-adsorption process in the recovery of gold and/or silver from ores, the screen within each tank which surrounds the slurry outlet is kept clean. The cleaning action is accomplished by linearly reciprocating the screen first slowly in one direction, and then quickly in another (to cause back flushing); or by rotating a cleaning rotor on the inside of a cylindrical screen. The cleaning rotor may be connected to the same shaft as an agitator disposed above a draft tube within the tank. The screen surface is tapered in its direction of movement, and during movement has a tendency to transport and concentrate the carbon (charcoal) particles at the far end of the slow stroke, and the concentrated particles can be withdrawn and recirculated to other tanks in the system.
