Spiral separator Wikipedia

网页Wet spiral separators. Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are

Size recovery curves of minerals in industrial spirals for processing

网页2014年10月15日Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992). The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottis, 1995, Burt, 1984, Bouchard, 2001).
