Spiral Separator | Spiral Concentrator | GTEK

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.

Spiral separators, Gravity Separation | GSL

Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.
