Spiral Concentrators — IMSC Group

Coal/Mica Spiral Spiral Concentrators Larger diameter units than the mineral-spiral series, these spirals are designed to take advantage of the particle shape differences. Take-off splitters at different points down the helix give this spiral a high capacity to remove refuse or siliceous contaminants from the coal or the mica.

Evaluation of ultrafine spiral concentrators for coal cleaning

2007; Benasa, 2007, and Mathew et al., 2008), spiral concentrators have the ability to achieve effective separations for particle size fraction of less than 150 µm down to 45 µm. The objective of this study is to evaluate the effectiveness of in-plant ultrafine spiral concentrators for cleaning ultrafine coal at size interval of -150µm+44µm.

Spiral separator Wikipedia

Wet Spiral Separators. 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
