  • Patent number: 5344025
    Abstract: Separation apparatus and methods separate ferrous, glass, plastic and aluminum articles in kind from each other when all articles are presented in a commingled stream. Ferrous articles are first removed by magnetic apparatus. The remaining commingled stream of glass, plastic and aluminum articles are conveyed over a vibratory screen for removal or residue materials not first removed prior to ferrous article separation. Plastic and aluminum articles are lifted away from glass articles in a vertically moving air column of a closed loop air flow system. The glass is conveyed past the column for further separation and collection while the plastic and aluminum articles are discharged together from a centrifugal classifier portion of the closed air loop. Large plastic articles are first removed from the combined plastic and aluminum, then aluminum articles are separated from the remaining smaller plastic articles.

  • Patent number: 5234109
    Abstract: An apparatus for recycling waste materials includes a first conveyor for conveying a combination of waste material including magnetic responsive metals, magnetic non-responsive metals, glass materials in both large and small particles, and plastics. A magnetic separator is positioned to receive the waste materials from the first conveyor and is capable of removing the magnetic responsive metals. A vibrating shaker screen then receives the waste materials and by virtue of its vibration causes the smaller broken glass to pass through spaces in the screen. Next, an air sorter including a large blower receives the waste materials and blows a stream of air across the waste materials so as to blow the lighter metals, such as aluminum and the plastics away from the remaining large glass materials, such as bottles. The glass bottles are carried away on a second conveyor, and the aluminum and plastics are carried away on a third conveyor.

  • Patent number: 4913804
    Abstract: The device consists of two fluidized bed tables (2, 3) which can vibrate on their support, an can be inclined as desired, allowing a common airflow to pass through. Located over the top end of the upper fluidized bed (2) is an inlet (1) for the granular material, opposite which, at the bottom end, is an outlet (14) for the very light granular fraction. At the top end of the lower fluidized bed (3) are a stone outlet (13) and, at the lower end, an outlet (15) for the heavy granular fraction. In addition, a chute (19) is situated between the fluidized beds (2, 3).

  • Patent number: 4529508
    Abstract: The invention includes a concentrator that pressurizes and provides an enriched liquid suspension to a separator. In the concentrator, the incoming liquid suspension is driven by a diaphragm pump into a funnel-shaped accumulator that is closed at its top. Some of the heavier particles go directly to the bottom of the accumulator, but the lighter particles and the remainder of the suspension are forced to flow through tubes that extend from the top of the accumulator upward on a helical path. Further particulate matter settles out in the helical passages and migrates to the bottom of the accumulator. From the accumulator, the concentrated suspension is fed under pressure to a separator that includes an inclined chamber that is completely filled with liquid. A stream of wash water is directed from the lower rear end of the separator towards the upper front end of the separator.

  • Patent number: 4207177
    Abstract: A material sorter to sort materials having various weight and aerodynamic characteristics such as, for example, relatively heavy magazines and corrugated cardboard from relatively lightweight newspaper. The sorter comprises a generally elongated hollow member having openings at oppositely disposed ends, the member preferably being a hollow cylindrically shaped tube. The axis of the tube is inclined with respect to the ground and the tube is rotated mechanically. The sorter also includes a source of forced air provided by a fan positioned at the lower opening of the tube, the fan is inclined at a variable angle with respect to the axis of the cylinder and provides a continuous spiral-patterned stream of air flowing upwardly through the cylinder. In the operaton of the material sorter, mixed paper having various weight and aerodynamic characteristics is placed in the upper opening of the tube. As the paper falls downwardly through the tube and is tumbled by the rotation of the tube, it separates.
