A New Spin on Flate Separation.Centrifugal continuous sortation Identifying objects that are stamped with a bar code and routing them to the appropriate destination. Sortation is typically a high-speed process used in the transportation industry by companies such as Federal Express, UPS and others. See sort and bar code. technology, originally developed for carpet recycling in Germany, is now being offered in the U.S. It can wash, separate, and dewater de·wa·ter tr.v. de·wa·tered, de·wa·ter·ing, de·wa·ters To remove water from (a waste product or streambed, for example). commingled plastic flake in a single stage. The Censor centrifugal sorting unit was developed by Baker Process, South Walpole, Mass., which has a system available for demonstrations and trials. The technology is also represented in North America North America, third largest continent (1990 est. pop. 365,000,000), c.9,400,000 sq mi (24,346,000 sq km), the northern of the two continents of the Western Hemisphere. by Action Industries Inc., Vernon, Conn. In the Censor process, a suspension of ground flakes in water is pumped from a tank into the spinning centrifuge centrifuge (sĕn`trəfy  j), device using centrifugal force to separate two or more substances of different density, e.g., two liquids or a liquid and a solid. cylinder that is partly filled with liquid. The cylinder spins at 2500 rpm, creating centrifugal force centrifugal forceFictitious force, peculiar to circular motion, that is equal but opposite to the centripetal force that keeps a particle on a circular path (see centripetal acceleration). 1000 times stronger than gravity and driving the liquid against the walls. When flake is introduced into the center of the centrifuge, it hits the high-speed sheet of liquid creating enormous turbulence that deagglomerates and cleans the flake. A central screw with flights angled toward the ends of the centrifuge turns in the opposite direction from the centrifuge's rotation, moving flake to discharge at both ends. Flakes that are lighter than water go to one end; flakes heavier than water discharge at the other. |
