- Spirals Separator Equipment For Iron
Particle separation in the spiral concentrator was simulated by discrete element methodology for the iron ore fines [21]. Performance of spiral concentration operation at different operating variables was analyzed for the feldspar-mica separation [28]. But it can be observed that, limited literature is available on recovery of ultrafine ...

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.
