  • Patent number: 8251226
    Abstract: The apparatus for separating residues from a thermal waste treatment into one fine fraction and one coarse fraction comprises a housing (1) abutting on swinging elements (2), said housing having a plurality of diagonally offset plates (3.1-3.5) that are disposed one beneath the other and are connected to said housing (1) by their side edges, and being equipped with means (5) for generating a vibration component oriented in the direction of the plates (3.1-3.5) disposed diagonally offset downward. The apparatus further comprises one suction line (6) as well as an inlet opening for a gas that may be passed between the plates for wind sieving. Residues or slag from a waste treatment plant or an incineration plant are supplied to this apparatus in order to separate them into at least one fine fraction and one coarse fraction.

  • Patent number: 4844235
    Abstract: A resilient liner is provided on the particle supporting surface(s) of a vibratory conveyor system. The liner accounts for a live surface that counters the tendency of the particles, particularly those that are moist and sticky, from adhering to each other and the conveying surface. The liner is particularly effective in systems such as separating systems wherein the particles at various stages fall to other levels.

  • Patent number: 4840727
    Abstract: A double bank cleaner for granular material includes two spaced banks of cleaning decks mounted in a frame with a drive motor and rotatable eccentric positioned between the two banks so that the banks of decks can be gyrated in a flat, horizontal plane. An aspirator for the double bank cleaner is also disclosed, and which comprises a plurality of feeders each of which creates a curtain of granular material through which air is passed to remove dust and the like.

  • Patent number: 4059508
    Abstract: A conveyor for granular material includes an elongated hollow channel covered by a suitable cover and having a hollow interior along which the granular material is to be conveyed. A rotary screw extends along the hollow interior of the channel for conveying the granular material therein, this rotary screw including an elongated shaft and a screw carried thereby. Between the opposed ends of the elongated shaft there is situated within the channel at least on bearing which supports the shaft for rotary movement, and a transverse wall extends across the interior of the channel and is supported thereby, this transverse wall carrying the bearing, so that the bearing together with the transverse wall carrying the same block the travel of the granular material longitudinally along the interior of the channel.
