Abstract: A comminuting device for breaking-up charge bodies of frangible material to free their value content and to reduce it to a desired size employs an upright enclosure into which charge bodies are fed so as to minimize in-air flow and to provide a steady stream of the bodies into the upper end of a centrally positioned downflow feed duct from which a series of horizontally, radially outwardly extending and vertically spaced-apart discs of a rotating assembly are suspended to define a central chamber selection passageway that is open at its upper end to the lower end of the duct, and at its bottom end through a grating to a motor drive compartment into which a fluid is introduced under positive pressure.

Abstract: A drum vacuum filter is shown which draws-in and radially outwardly projects the liquid content of a slurry or the like while the latter is advanced vertically along a passageway defined between a cylindrical rotating filter and a rotating drum wall, the latter of which collects and advances the solid material content of the slurry downwardly along the passageway for delivery and, as facilitated by a scroll scraper extending therealong. The liquid content is drawn under vacuum pressure induced force by a series of spaced-apart flutes or plates disposed along the exterior of the rotating filter, and radially or transversely outwardly with respect to the filter for segregated delivery with respect to the solid material content of the slurry or changed-in liquid.

Abstract: The apparatus and its process utilization enables a higher throughput of ore bodies being comminuted, provides a closer or more accurate selection of size of particles or particulates produced, has a low noise level in its operation, and uses its rotor impeller to facilitate the charging-in of ore bodies to be processed, the breaking-up of such bodies, and the delivery of such bodies in the form of sized particles or particulates is introduced by suction peripherally into one of the compartments of a motor-drive impeller and axially into all of the compartments, ore bodies are introduced into all of the compartments and are thrown under centrifugal force from one of the compartments against an anvil. Broken-up bodies of a desired size are fluidized and moved upwardly out of the apparatus while those of a rejected size are returned to the impeller for reprocessing with additional ore bodies being newly introduced therein.

Abstract: A mixing device employs a rotating hollow column or pipe that is motor-driven for rotation, is open at both ends to, at its upper or outer end, receive an inflow of a mixing fluid, such a gas or liquid, and its opposite or lower end, to simultaneously receive a co-axial inflow of a fluid-like or flowable charge material that is to be thoroughly and substantially uniformly mixed with the counter in-flowing mixing fluid.

Abstract: Contaminated liquid or sludge clarification is accomplished by the use of a basic one or a series of operatively connected and vertically extending units or devices of the invention, each of which employs a hose that is spiraled around a cylindrical container wall whose upper end is open to an overflow weir from which recovery of lower specific gravity clarified liquid is effected and whose lower end is open and connected to a cone or funnel-shaped wall that defines a receiving and delivering chamber for separated-out heavier specific gravity contaminating liquid, sediment, viscous or thickened material. The hose of the basic unit is adapted at its upper end to receive the contaminated liquid, sludge or the like and any suitable chemical flocculant, precipitant, or coagulant, such as a polyelectrolyte, that may be injected or added to the contaminated liquid before it is introduced therein.

Abstract: The inventive structure involves the provision and use of a rotating, fluted, impeller having sling compartments along a side thereof in which frangible materials are progressively introduced, are subjected to impaction with respect to each other and from which, after a build-up of radial angular velocity of the bodies, are projected forwardly radially outwardly with maximized face against a striker abutment and each other within a side-positioned quadrant zone.
