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. This creates a horizontal density differentiation of the feed materials, with the heavy particles flowing along the inside walls of the channel, and the faster lighter particles travelling higher up towards the outer rim. The discharge outlets are located on the inside of the channel for removal of the heavier material. Separation precision can be improved by adding additional water during the beneficiation process.
