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.
