A sheet manufacturing apparatus includes a screening unit having first openings for screening a defibrated material that is defibrating-processed; a refining unit that has second openings having sizes equal to or greater than sizes of the first openings and refines the defibrated material passing through the screening unit by causing the defibrated material to pass through the second openings; and a deposition unit on which the defibrated material passing through the refining unit is deposited.

A system and method for sizing and separating granular particles within the bulk granular solids by creating a graded granular flow comprising multiple sized fractions with gradation of the particles according to particle size between relatively fine fractions and relatively coarse fractions; and capturing at least a portion of granular flow. The system (11) comprises means (25) for creating the graded granular flow, and means (30) for capturing at least a portion of the graded granular flow. The graded granular flow is split into separate streams, one of which is subsequently captured by intercepting that stream. The intercepted stream may be collected or redirected for further processing.

A sheet manufacturing apparatus includes a classifier unit configured to classify by air flow an introduced material that has been introduced, a screening unit configured to allow a classified material, which comprises fibers, that has been classified by the classifier unit to pass through a plurality of openings to screen the classified material, and a forming unit configured to use a passed material that has passed through the openings to form a sheet. The classified material is supplied to the screening unit by the air flow.

A method is provided for pre-treating biomasses, more particularly, for pre-treating biomasses intended for a biorefinery or similar facility for producing biofuels. The method comprises the steps of shredding the biomasses, removing foreign bodies contained in the biomasses upstream of the step of shredding, and soaking the biomasses by immersing the biomasses in water upstream or downstream of the shredding step. A plant for pre-treating biomasses is also provided. The plant comprises a shredding station for shredding biomasses, a station for removing foreign bodies from the biomasses upstream of the shredding station, and a soaking station for soaking the biomasses upstream or downstream of the shredding station.

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.

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.
