摘要： A method and apparatus is provided for holding first material along with less dense material in substantially separate layers and for effecting removal of at least some of the second material to a location displaced from the layer. The materials are arranged in the two layers with the first material at the bottom of a vessel and with the second material disposed above the first material. An elongate withdrawal conduit projects into the vessel to define (1) an exit port at the wall of the vessel, (2) a confined flow passageway communicating with the exit port within the vessel, and (3) at least one withdrawal aperture with the uppermost portion of any withdrawal aperture being lower than the uppermost portion of the exit port. The upper surface of the first material layer is maintained below the conduit while flow of the second material from the second material layer is effected into and through the conduit via the withdrawal aperture.

摘要： 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. An island in the separator includes a rearwardly opening passage through which the enriched suspension from the concentrator enters the separator. The floor and ceiling of the separator chamber define between them an undulating passage from the back end to the front end of separator. The separated material is discharged from the separator through a unique pinch valve, while the wash water and finer particles are forced from the front end of the separator chamber through an upwardly directed helical path which provides further separation.

摘要： Washing tank for separating particles differing the specific gravity by means of a liquid separatory medium using the float-and-sink method. The washing tank is provided with at least one collecting tray for removing the settled particles, which collecting tray can be reciprocated along the bottom of the washing tank and in the first extreme position is about centrally on the bottom of the washing tank, where it can collect settling particles, and in the second extreme positions rests on the edge of the washing tank, so tilted that settled particles contained in it can slide into a discharge device positioned next to the washing tank. Preferably, the washing tank is provided with two alternating collecting trays hingingly attached to arms fixed on a horizontal shaft swinging to and fro between two extreme positions.

摘要： For screening oversized objects and especially long slender particles wherein the long dimension of the particle is aligned in the direction of flow through a fluid-flow conduit, there is provided a screen comprising a pair of opposing corrugated surfaces, the folds or corrugations on the opposing surfaces being substantially parallel, and separated by a distance, and having a wave length, determined by the size particle to be screened. Preferably, the corrugated surfaces are formed as two sets of a plurality of corrugated plates inserted within and extending along the direction of fluid-flow in a conduit, the sets being relatively movable between a position where the two sets are interleaved, and a position where the two are separated.

摘要： An improved method and apparatus for froth flotation separation of the components of a slurry, having particular utility for the beneficiation of coal by the flotation separation of coal particles from impurities associated therewith such as ash and sulfur. In this arrangement, a primary spray nozzle is positioned above a flotation tank having a water bath therein, and sprays an input slurry through an aeration zone into the surface of the water. The spraying operation creates a froth on the water surface in which a substantial quantity of particulate matter is floating, while other components of the slurry sink into the water bath. A skimming arrangement skims the froth from the water surface as a cleaned or beneficiated product. Moreover, a recycling operation is provided wherein particulate materials which do not float after being sprayed through the primary spray nozzle are recycled to a further recycle spray nozzle to provide a second opportunity for recovery of the recycled particles.
