摘要： The present disclosure relates to the field of mineral processing and separation, and in particular, to an underground coal hypergravity field separation system and a separation process. The separation system includes a grading hydrocyclone group, hypergravity field separators, feeding pumps, and conveying pumps. Coal collected underground is graded through a grading hydrocyclone first, then is fed into the hypergravity field separators for separation, and finally, is conveyed to a next link for dehydration through the conveying pumps. The separation system of the present disclosure has less supporting equipment, small floor area, and no complex pipeline, and is suitable for a downhole operation. In addition, the hypergravity field separators can provide a high-strength centrifugal acceleration, which can realize rapid separation of coal gangue particles in a radial direction and a tangential direction, and realize effective separation of fine coal gangue particles.

摘要： An apparatus and method for removing an underflow stream is provided suitable for removing an underflow stream from a separator, such as a mineral particle separator. In one aspect, the separator can include a discharge outlet for discharging the underflow stream, and the apparatus can include a source of pressurised fluid, a first conduit for fluidly connecting the pressurised fluid source to the discharge outlet such that the pressurized fluid is directed to impede the flow of the underflow stream in the first conduit, thereby creating a fluidisation zone, and a second conduit fluidly connected to the first conduit so that material from the fluidisation zone flows into the second conduit for removal from the apparatus.

摘要： A hydraulic particle separator is described. The particle separator comprises a main body having a top, a bottom, and a wall enclosing an interior cavity. At least one feed port is disposed on the top of the main body to introduce crude particle mixtures. A partition disposed within the cavity separates the cavity into a lower chamber and an upper chamber. The partition has at least one orifice for fluidic communication between the upper chamber and lower chamber. One or more grooves extend vertically along the interior surface of the wall. At least one tangential flow inlet port is disposed along the wall of the upper chamber above the partition.

摘要： Apparatus is provided including a signal processor or signal processing module configured at least to: respond to signaling containing information about particle sizes of solids forming part of a slurry stream being fed with a common feed flow into a battery of cyclones; and determine which combinations of cyclones in the battery produce overflow that has undesirable particle size characteristics using a statistical algorithm or technique, based upon the signaling received. The signal processor or signal processing module provides corresponding signaling containing about which combinations of cyclones in the battery produce overflow that has undesirable particle size characteristics, including control signaling to control the operation of the battery, including information about certain combinations of cyclones to avoid, or preferentially to use, to minimize the total amount of coarse material having the undesirable particle size characteristics produced by the battery.

摘要： An image processing circuit/CPU performs AF processing in response to a halfway shutter operation and upon confirmation of a shooting shutter instruction causes a light emitting unit in a flash circuit to emit light, and decides an amount of light to be emitted at a shooting time based on a brightness component of an output signal of an imaging element, whereby a subject distance is calculated from the amount of light emitted at shooting time, and wherein, when the in-focus decision in the AF processing is negative, an optical lens is moved by a lens drive circuit to a position corresponding to the subject distance which has been acquired based on the amount of light emitted at the shooting time, and a shooting operation is then performed.

摘要： A water-excluding vent structure wherein water impinging upon an outer surface thereof is excluded while air is allowed to freely flow through the vent structure to an internal space. The circular or other appropriate shaped vent structure has a series of parallel louvers designed for orientation in a level, horizontal plane. A porous, polypropylene membrane is placed behind the louvers. A perimeter gasket is used to seal the vent structure to the object to be ventilated. A notch is formed in an inner edge of the perimeter gasket along a line which is a perpendicular bisector of the louvers. The space defined by the notch is communicative with a drain hole in the outer housing. When properly oriented with the notch in a lowermost position, any moisture passing through the porous membrane collects in the notch and flows through the drain hole.

The fluidized layer (22) causes the organic material to be separated from the inorganic material. The discharging apparatus (24) is located in the lower portion of the container (1), and it serves to discharge inorganic material from the container (1). The removal apparatus (7) is located in the upper portion of the container (1), and it serves to remove organic material from the container (1).
