Gravity Separation For Fine Particles Low G-Force Gravity Concentrators. The difference between a g ravity concentrator and the other gravity separation devices previously discussed is the ability to increase the forces on the mineral particles that improve the particles’ settling in a water medium. Instead of relying on one G force (the
As the most simple gravity separation technology, and arguably the most efficient, spiral concentrators have long played an important role in minerals processing. The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores.
Gold Centrifugal Concentrator is an efficient gravity separation machine that is useful in the recovery of free gold in all ranges of particle size, especially useful for recovering fine gold which gets lost during the operation of gravitational concentrators.

These gravity concentrators are precisely designed and built from high-quality materials that provide a long service life, lower costs of operation and low maintenance. The science behind the spiral. Spiral concentrators are simple low energy-consuming devices used for mineral separation mainly on the basis of density or by shape.
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.
Figure 2 Cross section of a Spiral Concentrator  Theory of Operation Slurry is introduced at the top of the concentrator and as the material flows downward a combination of centrifugal and gravity forces act on each respective particle, which results in the segregation of the coarse lights and fine heavies . Separation
Spiral Concentrators (Flowing Film) Separation by density occurs as a result of primary flow and circulating secondary flow patterns that are created as the feed slurry travels along an elongated helical trough surface that spirals downward around a central axis.
The MX7 spiral separator is ideal for difficult-to-wash coals, improving the overall efficiency of tougher separation applications. These spiral separators are precisely designed and built from high-quality materials that provide a long service life, lower costs of operation and low maintenance.
