Spiral Concentrators NobleMEIR, Inc.

Spiral concentrators are a gravity based concentrating device, that separates light density granular and sandy (17 mesh to 340 mesh (1 mm to 0.075 mm)) 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.
