Spiral Concentrators. Single Start Spiral. Spiral concentrators are a gravity based concentrating device, that separates light density granular and sandy (18 mesh to 200 mesh (1 mm to 0.075 microns)) consistency material from heavier density material. In order to have a good separation, there should be a difference in SG's of at least 1.0.
