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.
