  • Patent number: 7514011
    Abstract: A system for separating solids from a fluid stream. The system includes a first separator device mounted to a container. The container includes a settling compartment and baffle plate module, with the initial settling compartment receiving the fluid from the first separator device. The fluid stream proceeds through the baffle plate module. The solids within the fluid stream will descend to the bottom of the container. A spiral blade is positioned at the bottom of the container, with the spiral blade adapted to convey solids to a first pump member. The speed of rotation of the spiral blade may be varied. The first pump member discharges the slurry to a second separator device. The second separator device will discharge the separated fluid stream into the baffle plate module. In one embodiment, the first separator device is a linear shaker and the second separator device is a cyclone separator and linear shaker mounted in tandem.

  • Patent number: 7500806
    Abstract: A method and apparatus for constructing a filter zone of an earthfill dam, in which the filter zone includes adjacent coarse and fine filter layers. The coarse and fine filter materials are discharged simultaneously from an earthmoving vehicle having an ejector body. The ejector body includes a longitudinal divider wall that maintains segregation of the materials during transport, and the materials are discharged through separate chute assemblies so as to place the materials in elongate, side-by-side berms. The ejector vehicle is followed by a dozer or other piece of equipment that grades both berms simultaneously. Each pass of the ejector vehicle and dozer thus forms a stratum of the filter zone. The passes are repeated to form a plurality of strata in overlying relationship such that the coarse particulate material forms the coarse filter portion of the filter zone and the fine material forms the fine filter portion of the zone.

  • Patent number: 5411147
    Abstract: A dynamic landfill recycling system has wheels attachable to a plurality of refuse processing sections in one or more semi-trailer or other vehicular units. A refuse receiving section has a dump bed or one or more vehicular refuse bins to accept new refuse from refuse trucks or optionally to accept old refuse from old refuse sites for processing, A primary conveyor belt is slanted upwardly towards a vibratory feeder. The primary conveyor is rotated rapidly to throw the refuse in an arc onto the vibratory feeder where the throwing action causes the refuse to spread out as it falls. The vibratory feeder is slanted downwardly at an angle which causes vibrated refuse to fall towards a bottom end and a bag cutter that is positioned above and intermediately between ends of the vibratory feeder to further expose and scatter the refuse on the vibratory feeder. A magnetic separator belt conveys the scattered refuse upwardly to a magnetic pulley wheel which separates ferrous from non-ferrous materials.

  • Patent number: 4616786
    Abstract: Surplus concrete or return concrete to be processed is poured into a high-capacity receiving bin and is transferred at a metered rate from said bin by means of a screw conveyor to a washing apparatus, in which fine components are separated from very fine components. The transfer at the metered rate is effected in dependence on the driving power of rotary motors of the rotary washing apparatus. When the driving power of the motors exceeds a predetermined value, then the motor of the screw conveyor is deenergized. When the driving power decreases below that value or below another value, the supply at the metered rate is resumed. The plant operates fully automatically and when the receiving bin has been emptied the plant is automatically cleaned and automatically shut down.

  • Patent number: 4231478
    Abstract: Method and apparatus for bulk sorting particulate material such as ore rocks. A conveyor belt carries the material in a continuous stream past a detector responsive to a required characteristic to produce a time sequence of detector signals dependent on degree to which material passing the detector possesses that characteristic. The material is projected from the downstream end of the conveyor belt into free flight trajectory and a deflector plate is moved across the face flight path so that material in some zones of the stream is deflected whereas material in other zones is not deflected. A control circuit monitors the detector signals and causes the deflector plate to move so that said zones are determined by the degree to which the material in them possesses the required characteristic.
