摘要： A method and device are used for separating particles of plastic foil from organic material. The device includes a chamber with a perforated wall. A mixture of particles of plastic foil and organic material is fed into the chamber through a feed opening. The mixture is set into a rotating movement inside the chamber by a rotor. In the vicinity of the perforations, the centrifugal force to which a particle is subjected is at least fifty times greater than the gravitational force to which the particle is subjected. An airflow is generated in the chamber parallel to the rotational axis of the rotor. Particles of organic material leave the chamber through the perforations. Particles of plastic foil are carried along by the first airflow and then discharge through an opening in the chamber.

摘要： A method for fractionating a milled grain product into coarse and fine fractions includes providing a sieving apparatus with a bottom chamber divided from a top chamber by a sieve, an inlet port in the top chamber, a top chamber cover defined by a plurality of openings, and a first exit port in the bottom chamber, and applying vacuum suction to the sieving apparatus. The vacuum suction is configured to draw grain particles through the inlet port into the top chamber, generate substantially horizontal airflow in the top chamber via the inlet port; and generate substantially vertical airflow in the top chamber via the plurality of openings, wherein the substantially horizontal airflow and the substantially vertical airflow combine to generate turbulence which fluidizes the grain particles in the upper chamber and prevents blockage of the sieve; and drawing fine grain particles through the sieve and out of the bottom chamber via the first exit port under the vacuum suction and collecting a fine grain particle fraction.

摘要： There is disclosed a method and apparatus for separating stones, fibers and plastics from biodegradable material. In an embodiment, the apparatus comprises: an inclined trough having a feed entry at a top end for receiving the feed material, the inclined trough including a plurality of riffles angled to at least partially hinder and unsettle a flow of the feed material flowing down the inclined trough; one or more vibratory motors configured to induce a vibration in the inclined trough; one or more blowers configured to generate an air flow through overhead air vent nozzles positioned over the inclined trough and directing the air flow to one side of the inclined trough; and a material resilience separator for separating the contaminants from the biodegradable materials in the remaining material.

摘要： Provided is a dry separation apparatus including: a main body; a first deck; a plurality of guides; a supply part; an air blow fan; and a vibration part. A dry separation method includes: supplying an object to be separated to a top surface of a first deck provided with a plurality of punches; sending, by an air blow fan, air to the punches (first punches); and horizontally vibrating, by a vibration part, the first deck so as to discharge particles which have different specific gravities of the object to be separated and a moveable force exerted by air passing the first punches through different passages.

摘要： A classifying fluid bed granulation unit includes a perforated bed floor; a fluid bed section; a solid feed inlet or internal crushing device; a fluidization air inlet; a liquid solution or melt feed inlet and nozzles; an air outlet; and a product outlet; wherein the fluid bed section comprises at least one particle classification element comprising one or more vertically inclined channels having top and bottom end feed openings, and wherein the one or more vertically inclined channels have upper and lower side slots. In operation of the above fluid bed granulation unit, each channel of the element is separating particles into large particle and small particle fractions and transporting the large particle fraction upwards and the small particle fraction downwards in each channel, and the large particle and small particle fractions are transported out of the upper and lower side slots, respectively.

摘要： 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.

摘要： 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.
