  • Publication number: 20090162137
    Abstract: A lined drum includes a drum having a wall with an inner surface. The lined drum also includes a plurality of liner segments, each liner segment having inner and outer opposing surfaces, opposing side edges, and opposing end edges, the outer surface of the liner segment facing the inner drum surface and the side edges of adjacent liner segments being spaced from each other to define a space therebetween, and at least one retainer having opposing side edges overlapping the side edges of the adjacent liner segments, the at least one retainer attached to the wall of the drum in the space between the side edges of the adjacent liner segments. The lined drum may also include a plurality of bar segments, each bar segment attached to the wall of the drum and at least one retainer.

  • Publication number: 20080210718
    Abstract: A vibratory apparatus includes a trough assembly comprising first and second plates, the first and second plates joined together in close proximity so as to define a space through which a fluid may pass at a high velocity, a vibration generator coupled to the trough assembly, and a frame resiliently coupled to the trough assembly. Also included is a system including the vibratory apparatus and other equipment, and a method of using the vibratory apparatus.

  • Patent number: 5984105
    Abstract: In order to separate two classifiable materials, a material classifying apparatus includes a vibratory conveyor for conveying a fluidizable material from a material to be separated therefrom from an inlet end through a material separation section to an outlet end located downstream of the material separation section. A plenum chamber directs air upwardly through the fluidizable material and the material to be separated therefrom in the material separation section of the vibratory conveyor to cause fluidization of the fluidizable material and separation of the material to be separated therefrom by forming the material separation section to include a fluidizing deck for supporting the two classifiable materials while accommodating passage of air upwardly from the plenum chamber therethrough.
