Abstract: A delumper includes a housing defining a chamber in which edible material is received. The housing includes a screen having a plurality of holes and a plurality of inwardly extending fingers. The holes are sized such that edible material of a first diameter is capable of passing through the holes and edible material of a second, larger diameter is incapable of passing through the holes. The fingers are arranged in at least a first row, and the first row is located at or between a 5:00 position and a 7:30 position. The delumper further includes a rotatable shaft including a plurality of paddles spaced along a length of the shaft. When the shaft rotates, each of the paddles passes between adjacent fingers of the first row such that edible material located within the chamber is forced into contact with the fingers and cleaved by the paddles.

Abstract: A rotary milling system includes a rotatable cylinder, a discharge grate, a discharge housing surrounding the grate, a valve moveable between an open and closed position being in fluid communication with the discharge housing, and a conveying pipe extending from the valve. The cylinder can include grinding media for abrading a product when the cylinder is rotated. The product is suspended and ground within a liquid medium. Upon conclusion of the milling, the valve is opened to allow the liquid medium and milled product to pass through the discharge housing and the conveying pipe. The liquid medium can flow back and forth through the grate during the milling operation, with the valve preventing discharge before conclusion. A liquid-drawing apparatus can be used to draw the milled product through the conveying pipe into a separator tank after opening the valve.

Abstract: This invention relates to a spouted bed wood chip debarker/cleaner. Such structures of this type, generally, cause wood chips and bark to undergo attrition by accelerating the wood chips and bark with a jet of air. In particular, the accelerated wood chips and bark are impinged on a screen. When the wood chips hit the screen, bark and wood chips experience attrition. Small pieces of bark and other debris (sand, for example) will be exhausted through the screen which is too fine of a mesh to let desirable size wood chips be exhausted.

Abstract: A motor driven grinding apparatus, and a system incorporating the inventive grinder, for reducing the size of waste material. The apparatus includes a housing having an interior, an exterior, an inlet for introducing material into the interior, and an exit for expelling material from the interior. The housing also includes a front wall, a back wall, a pair of spaced apart side walls, and a bottom grate. The apparatus also includes a substantially cylindrical, balanced, drum having a shaft, and a plurality of cutting blocks rotatably mounted thereto. The drum is rotated by a drive motor engageable with the shaft. An airfoil is attached to the front wall for establishing a static air curtain within the interior of the housing enabling air to be drawn into the housing through the inlet and expelled from the exit when the drum rotates. The drum and cutting block configuration are particularly useful for grinding, and sheafing, cellulose, plastics, glass, and other solid waste materials.

Abstract: The system of the invention includes: a self propelled vehicle having a bed for receiving debris after comminution has occurred. The bed includes a cover.

Abstract: A method and apparatus for communicating feed stock in the form of shreds or the like to form a low density particulate product. The shredded feed stock is fed to a material handling rotor that functions as a centrifugal blower. The apparatus includes a housing that defines a cylindrical rotor chamber formed about a horizontal axis and a volute-shaped internal passage having at least one convolution formed around the rotor chamber. Located within the housing is a cylindrical screen with perforations that open into the rotor chamber. The centrifugal blower rotor is mounted in the rotor chamber and has a plurality of radial vanes with rakers attached to the outer ends closely spaced from the inner surface of the screen so that they continuously wipe pass the perforations to prevent clogging or blinding.

Abstract: Used foundry sand which is predominantly in the form of lumps containing a binder for the sand particles is regenerated. In the course of the regeneration, the lumps are comminuted and, simultaneously therewith, an at least partial separation of the sand and the binder is effected. The simultaneous comminution and separation is effected by a dry, mechanical procedure during which the lumps are subjected to an abrasive or scouring action. This is accomplished by means of a pair of vibrating or rotating brush-like members provided with steel bristles. These members are located adjacent the bottom of a trough-shaped strainer which permits the passage of sand particles having a size less than a predetermined size. A cover is provided for the strainer and serves to cause rebounding of particles which impinge upon it. A feed hopper feeds the lumps of used foundry sand to the brush-like members and a bar overlying the gap between the latter prevents entry of the lumps into the gap.
