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.
