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.

The tracer particle trajectories and the free surface velocity of a spiral were determined with a high-speed camera. An increase in the flow rate leads to an increase in the liquid depth and free surface velocity along the trough surface. Three full turns of the high gravity spiral concentrator are sufficient for achieving a stabilized flow.
