FREMGANGSMADE TIL MEKANISK AFVANDING OG TERMISK TORRING AF KORNEDE FASTE STOFFER NAVNLIG AF SYNTETISKE SPINDEFIBER-RAGRANULATER OG CENTRIFUGE TIL GENNEMFORELSE AF FREMGANGSMADEN

摘要

Water is separated from a mixture of a granular material with water by first separating by a screen all water which is not retained by the granular material, and flows through the screen by the action of gravity. At the same time, the granular material and the retained water is supplied to zigzag-shaped radial channels of a centrifuge where slanted screens separate retained water from the granular material. Water still adhering to the granular material is evaporated by streams of air blowing into the outer end of the zigzag-shaped channels, and into a discharge duct for transporting the granular material to an outlet while evaporating still adhering water.
