Abstract: A device for sorting flat-area piece goods, particularly packets, packages, and letters. This device has a drum cylinder open towards the outside at both faces, and mounted at an angle to rotate on a bearing body on the mantle surface of the cylinder. The cylinder is structured with longitudinal rollers that rotate about their longitudinal axis, arranged at a distance from one another, mounted on annular flanges, whereby the longitudinal rollers are arranged as steps that extend towards the inside. In each instance, the steps are formed of a roller arrangement of longitudinal rollers. According to an alternative particularly preferred embodiment there is a device with longitudinal rollers that can be put into rotation about their longitudinal axes by a drive. This device has longitudinal rollers that can be put into rotation about their longitudinal axes by the drive.

Abstract: A method and apparatus for efficiently separating solids from liquid/solid slurries are disclosed. The slurry to be separated is retainably placed within a container having one or more lift paddles secured within its inner cavity. The container is supported for rotation about an axis and has drive means for slowly rotating the container. As the container rotates, the lift paddles lift a portion of the retained slurry, allowing the liquid portion to fall back into the primary slurry pool to be separated, and lifting coarse solids toward the top of the rotation path of the paddles. The separated solids slide by gravity from the lift paddles as they approach the top of their rotation paths and into a collection tray. A filter that rotates with the container filters fine solids from the liquid portion of the slurry and also deposits the fine solids on the collection tray. The filtered liquids can be readily pumped from or recirculated to the separator.

Abstract: An apparatus for refining clay material having a horizontally oriented rotating drum into which clay material and water are fed. The clay material and water form a slurry which is agitated by lifters within the drum. A series of adjustable lifters within the drum refine the slurry by lifting aggregates and rocks out of the slurry and discharging them out of the refiner. The refined slurry exits the drum through an opening in the drum. The refined slurry is then taken away from the drum for further processing.

As the container rotates, the lift paddles lift a portion of the retained slurry, allowing the liquid portion to fall back into the primary slurry pool to be separated, and lifting the solids toward the top of the rotation path of the paddles. The separated solids slide by gravity off of the lift paddles as they approach the top of their rotation paths and into a collection hopper and transport means that carry them away from the container. The liquids returned to the primary retained slurry within the container assist in washing the slurry for facilitating solids separation without required increase in the retained slurry volume.

Abstract: A strainer comprises a housing. A main screen is disposed within the housing. The fore screen is disposed within the housing and includes a first section and a second section. A main beater is connected to the second section of the fore screen. The fore screen and the main beater are moveable with respect to the main screen. An auxiliary beater is connected to the second section of the fore screen. The auxiliary beater is moveable with respect to the first section of the fore screen.

Abstract: The present invention is a barrel screen apparatus comprising an elongate, hollow, cylindrical and rotatable barrel screen cage having a receiving end and a discharge end. A hopper is positioned adjacent to the receiving end of the barrel screen cage and has a pair of augers to convey the material and regulate the rate of feed into the feed end of the barrel screen cage. A concave plate is attached to the support frame and positioned directly below and along the length of the barrel screen cage to catch the screened material through the cage. Spiral flighting is attached to the external periphery of the barrel screen cage to convey the material forwardly on the concave plate towards the front of the apparatus where stripper bars, mounted longitudinally on the periphery, push the material off the side of the apparatus. The material accumulates adjacent to a fold-down apron on the side of the apparatus which facilitates pickup by a front-end loader or other means.

Abstract: Apparatus for use with extremely low-grade aggregate ore, for deriving a concentrate comprised of metal-bearing ore particles having densities within a predetermined range. The apparatus is in the form of a mobile, self-sustained system including a vehicle trailer for horizontal transport and elevated operational support, plus an integral power system capable of supplying the total energy requirements of the apparatus. Two types of particle size separation are applied, followed by compaction and particle density separation. Two density separation areas are provided to effect both coarse and fine gravitational shaving actions, and dual adjustment controls are also provided to vary the shaving force intensity to derive the concentrate independently of changes in the particular characteristics of the aggregate being processed. The apparatus includes outer and inner cylindrical chambers concentrically mounted on the trailer so as to be tiltable and rotatable.

Abstract: Method and apparatus for shelling vegetable peas and separating the hulls from the pea, in which the method and apparatus includes a tumbler and agitator for displacing the pea from the hull, agitator which shells the peas, and a separator of novel design and function for separating the hulls therefrom.
