  • Patent number: 5593042
    Abstract: The novel invention proposes a final screen which is very reliable in operation and which is suitable more particularly also for building into a pneumatic conveying line. In a first section the material is distributed uniformly over the entire peripheral surface of the screen shell. The subsequent section is used for completing screening and separating the coarse material out through an outlet. A centrifuging rotor with helically arranged elastomeric cleaning lobes projecting from the centrifuging bars provide a high throughput and particularly damage-obviating discharge of even relatively large foreign bodies.

  • Patent number: 5072991
    Abstract: A floating grab dredge has first and second pontoons spaced apart sufficiently to define a work space therebetween. The work space is large enough to define a barge slip therein as well as a digging well adjacent to the barge slip. A gantry mounted on the pontoons by supports spans the work space. Material handling apparatus on one of the pontoons includes a grizzly for separating waste from recoverable material. The gantry includes tracks on which a trolley shuttles among positions above the digging well, barge slip and grizzly. When a load of dredged material is brought up from the digging well it is inspected to determine if it contains recoverable material. If it does the trolley is moved above the grizzly and the load is dumped on the grizzly. If no recoverable material is in the load, it is dumped into a barge in the barge slip and digging continues.

    Abstract: Apparatus for the refinement of colloidal asbestos dispersions comprises a horizontally disposed cylindrical tube having a plurality of closely spaced holes around the periphery thereof, a helical screw disposed within the tube, and a flanged jacket concentric with and spaced outwardly from the tube. A slurry of unrefined dispersion is continuously fed into the tube to fill it. Refined slurry is drawn through the holes by a suction pump connected to the jacket while contaminants are retained in the tube and moved by the screw to the outlet end of the tube where they are compacted and removed as sludge through a spring loaded discharge door.

  • Patent number: 3998396
    Abstract: In a low profile crusher which has first and second cylindrical rolls journaled so that the rotational axis of the rolls are parallel and an input conveyor and an output conveyor is improved by journaling the first roll so that the distance from the axis of the first roll to the product side of the output conveyor is slightly greater than the radius of the first roll. The input conveyor is mounted over the first roll so that the distance between the axis of the first roll and the return side of the input conveyor is slightly greater than the radius of the first roll. The second roll is journaled above the first roll so that the maximum height of the second roll is at least equal to the height of the product side of the input conveyor and close enough to the first roll to produce a predetermined maximum size of product. A scalping method for the above is formed by mounting the input end of the input conveyor in substantially the same plane as the output conveyor.
