As a matter of fact, the spiral concentrator is also called Wet Spiral Separators. In other words, the Wet Spiral Separator and the spiral concentrator are the same mining machine product. But are you familiar with the spiral concentrator?

The 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 extract solid particles that have come out of suspension. Spiral troughs are manufactured from high-quality polyurethane resin with a fibreglass backing. The combination of raw materials used in the production of Multotec spirals has been proven to result in superior adhesion between the two layers, and delamination problems are virtually unknown. For maximum wear life, high-wear areas are manufactured with increased Polyurethane thickness.

Spiral concentrators are a gravity based concentrating device, that separates light density granular and sandy (10 mesh to 200 mesh (2 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. One main benefit of spiral concentrators is they have no moving parts. The feed range, in percent solids, to a spiral ranges from 20% solids up to 40% solids. Depending upon the material characteristics, a maximum efficiency will usually be reached somewhere in this range.

Typical spiral concentrators will use a slurry from about 20%-40% solids by weight, with a particle size somewhere between 1.5-.075mm (17-340 mesh), though somewhat larger particle sizes are sometimes used. For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm3.
