  • Gravity Spiral Concentrator Working Principle

    Spiral concentrators will tolerate minor feed variations without requiring adjustment. Spiral concentrators, like cone concentrators, are efficient, low-maintenance units that should be considered for any large- scale gravity separation system. The newer Humphreys spirals are capable of recovering particles as small as 270 mesh (53 microns).

  • Simulation of particle-laden flow in a Humphrey spiral

    The curvature of a spiral channel is one of the important design factors, because it primarily determines the profile of the free surface and therefore the structure of secondary circulation. Despite the importance of the curvature profile, its influence on particle separation has not been investigated in most studies on spiral concentrators.
