The spiral concentrator is a modern device that works on a combination of solid particle density and its hydrodynamic dragging properties. The spirals consist of a single or double helical conduit or sluice wrapped around a central collection column. It is used for concentration of low-grade ores and industrial minerals in slurry form.

The spiral concentrator is a mineral processing device that separates mineral particles according to their densities and to a lesser extent particle size. In this thesis, a four-turn WALKABOUT PW1 spiral concentrator was used to investigate the particle movement inside the trough of spiral concentrator. For the experiments, a synthetic
some proxy for monitoring benefit. Spiral concentrator and spiral plant modelling (including optimal sensor placement) is based on the case study of the Glencore Rowland spiral plant which treats slurry containing UG2 ores to upgrade chromite content. Algorithm CVII proved to be the superior interface detection approach and can identify chromite

Working Principle. Spiral Separators, which are also called Spiral Concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. The heavy frictional forces slow their velocity. As a result, faster particles higher up in the flow.
