  • Spiral Concentrators - Mine Engineer.Com

    Spiral concentrators are normally used in banks of multiple spirals. Typical capacities for spirals run from 1-3 tons per hour of feed for minerals and 3-5 tons per hour for coal. Typical construction of a spiral concentrator is fiberLimestone and urethane to reduce wear from abrasion. Charles Kubach, Mining and Mineral Processing Engineer

    Feed DistributorOperating ParametersFeed DistributionSplitter PositioningA gravity feed slurry distributor, mounted centrally on top of the spiral module, ensures even distribution of feed to each spiral start. The distributor body is constructed of fiberLimestone and the wetted surfaces are lined with wear resistant polyurethane. The center mixing column and hoses (not shown) are made of durable and replaceable HDPE and the outlet pipes are constructed of polyurethane. Standard distributors are available with up to 48 outlets in either top-fed or bottom-fed configuration. An example
  • Spiral separator - Wikipedia

    OverviewWet Spiral SeparatorsDry Spiral SeparatorsSee alsoReferences and further reading

    Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag). The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid particles that have come out of suspension.

    A comparative study was conducted on the treatment of fine coal using DMC and spirals and it was proved that DMC is superior to spirals in treating coal fines (Ma et al., 2018a). Higher coal yields and combustible recoveries were obtained due to high centrifugal force which is an upper hand factor of a cyclone. The energy consumption and magnetite loss to clean coal is however compensated by ...
