An apparatus for separating usable crop from intermixed debris. The apparatus has: a) a conveying system configured to convey usable crop in a processing path from an upstream input location to a downstream output location; and b) a first separating system configured to cause separation of debris intermixed with usable crop as usable crop is conveyed in the processing path. A vacuum system downstream of the preliminary separating system is configured to: a) generate a low pressure volume which causes additional debris intermixed with usable crop to be drawn away from usable crop by vacuum; and b) cause drawn debris to be directed towards a collection location spaced from the output location while allowing usable crop to advance toward the output location.

An exemplary sieve mechanism is configured for separating grain from chaff. The sieve mechanism generally includes a frame and a louvered region including a plurality of louvers mounted to the frame. The sieve mechanism further includes and an unlouvered region lacking louvers such that a gap is defined adjacent the louvered region.

The disclosure provides a process for obtaining the purest form of Himalayan pink salt. The purest form of Himalayan pink salt is preferably in crystal in form and is substantially clear and colorless. The disclosure provides a purification process that identifies and removes solid impurities affording the purest form of Himalayan pink salt. The system may machine vision algorithms that process feedback from one or more sensors to detect and identify color or clarity, and may use one or more host controllers to remove solid impurities. The controller may identify the color or clarity and ensure consistent removal of the solid impurities.

A separating device separates liquid absorbent fibers from a material including the liquid absorbent fibers of an absorbent article and impurities. The separating device includes: a case; an insertion port for inserting the material into the case on an airflow; a rotation member in the case for agitating and opening the material; and a discharge port for discharging the liquid absorbent fibers from inside the case on an airflow. The rotation member has a revolving axis with an axial direction along a predetermined direction from the insertion port to the discharge port, and a shaft member rotating around a rotating axis that has been set with an axial direction along the predetermined direction, while revolving around the revolving axis. The shaft member has protruding sections protruding outward and intersecting with an axial direction of the shaft member.

Methods and apparatus for separating polysilicon powder from a mixture of granular polysilicon and polysilicon powder are disclosed. The method includes tumbling the polysilicon material in a tumbling device while flowing humidified sweep gas through the tumbling device. Also disclosed are compositions including granulate polysilicon or polycrystalline silicon, in some examples, including a coating layer consisting essentially of water.

A separator attachment for use with a vibratory apparatus, the attachment including a housing mountable to a vibratory apparatus below a material-conveying surface of the vibratory apparatus, the housing defining a pressure chamber with an inlet and an outlet. The housing has at least one wall with a wall surface having a first end disposed proximate to the outlet of the pressure chamber and a second end. The attachment also includes a deflector plate with a deflector plate surface having a first end disposed proximate to the outlet of the pressure chamber and a second end, the deflector plate surface facing the wall surface. The deflector plate is translatable relative to the at least one wall to vary the spacing between the deflector plate surface and the wall surface. A system including a vibratory apparatus and the attachment may also be defined.

Screen for separating solid residues, and in particular for separating sheet or expanded material, such as bags or parts of bags made of plastic, polystyrene, spongy material or another light material, which comprises a separation station (10) interposed between the inlet port (P1) and the outlet port (P2) of the screen above its screening surface (P) and preferably after the powders and the lightest portions have already been separated. The station (10) comprises a hood (11) delimiting a suction chamber (13), and insufflation means (15) for orienting at least one lifting air flow (16) in the suction chamber (13) at the screening surface (P). The lifting air flow (16) is oriented for forming a vortex (17) confined in said suction chamber (13) and with rotation axis (Z) orthogonal to the screening surface (P) capable of lifting the sheet material and delivering it to suction means (18) associated with the hood (11).
