    Abstract: A seashell collecting and crushing apparatus includes a collection device having a hollow body and an inlet for introducing seashells into the hollow body. A fan assembly is operable to provide a suction airstream for drawing seashells into the hollow body. A crusher is positioned to receive seashells from an outlet of the collection device and pulverize the seashells received from the collection device into a fine particulate matter releasable through an outlet of the crusher. The fan assembly and the crusher are driven by a common driving arrangement. A method includes using the apparatus for removing seashells from the beach using the suction airstream to introduce seashells through the inlet into the hollow body, separating the seashells entering the hollow body from the suction airstream, pulverizing the seashells into a fine particulate matter using the crusher and exhausting the fine particulate matter through the outlet of the crusher.

    Abstract: Shredded scrap is conveyed from a heat generating automobile shredder to one end of a horizontal tumbling drum and is caused to move in one direction through the drum as it tumbles. An air stream which has aspirated heat generated by the shredder, and carrying particulate material removed from the scrap in the shredder, is directed by ductwork to the opposite end of the tumbling drum where the air and particulate matter move in counterflow through the tumbling scrap to remove additional particulate material therefrom as the shredded particles are being showered through the air stream. The particulate material in the air stream emerging from the tumbling drum is separated out by a cyclonic separator. A bypass air stream duct with an adjustable valve bypasses some of the air stream around the tumbling drum to control the velocity of the air stream through the tumbling drum and thus to control the size of the particulate material removed from the scrap by the counterflow air stream.

  • Patent number: 3987968
    Abstract: A moist pulp fiberization device wherein picked moist pulp enters a tubular chamber behind a fiberizing blade mounted coaxially within the chamber, the fiberizing blade being configured to produce a turbulent vortex with little, if any, pressure differential within the chamber, the flow of pulp through the chamber being induced and controlled by drawing a vacuum on the trailing end of the chamber and providing an adjustable orifice plate intermediate the fiberizing blade and the trailing end of the chamber; if required, the fibers withdrawn from the chamber may be successively introduced into one or more additional chambers of like configuration to effect substantially complete fiber separation, whereupon the separated fibers are discharged for subsequent processing and use.
