  • Coal Spirals Concentrators from Krebs : Quote, RFQ,

    Krebs Coal Spirals are used to make density-based separations on nominal 14M x 100M (1.19mm x 0.149mm) size coal. These devices consist of a 0.96-meter Ø helix with between 2 and 3.25 turns, mounted on a 160-mm Ø center column. To provide greater capacity per volume, either two (duplex) or three (triplex) helices can be mounted on one center column.

  • Gravity Spiral Concentrator Working Principle

    2020-6-25  The processes involved in mineral concentration by spirals are similar for all models. As feed containing 25-35% solids by volume is fed into the channel, minerals immediately begin to settle and classify. Particles with the greatest specific gravity rapidly settle to the bottom of the spiral and form a slow-moving fluid film. Thus the flow ...
