Heavy minerals such as ilmenite or hematite settle out rapidly in a spiral concentrator and they should be removed as soon as a good wide band forms. Since the concentrate band is wider at the top, splitters near the top of the spiral concentrator should be opened wider than those near the bottom.

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 placed in the base of the sluice to ...

Concentrator Flows ABSTRACT Spiral concentrators are used globally in the fine coal processing industIy to segregate particles, by grnvitation, on the basis of density and size. Consisting of an open trough that twists vertically downwards about a centrnl axis, a sluny mix of particles and water is fed to the top of the concentrator.

Introduction In a recent survey of worldwide coal preparation practices, it was reported that spiral concentrators treat 6% of the coal treated in processing plants (Kempnich, 2003). The application is typically associated with cleaning the 1 · 0.15 mm fraction of the plant feed. The popularity of spiral concentrators is due to their ...
