The spiral separator integrates the features of the spiral concentrator, shaking table and centrifugal separator. JXSC produce mining equipment since 1985.
In a spiral concentrator, the denser materials flow down along the inner section of the trough, and the less dense material flows along the outer section. In order to enhance the separation at fine particle sizes, or low concentrations of high value material (such as gold), a centrifugal force may be imparted on the slurry, increasing the ...

Since the classification in a spiral concentrator depends on particle specific gravity and size, the operation of spirals can be analyzed using size recovery or partition curves (Bazin et al., 2014). Spiral concentrators possess multiple design parameters for a variety of applications.
The water washes lighter particles down the spiral concentrator into a bucket while denser particles, including gold, are carried by the spiral grooves toward the hole in the center of the concentrator.

Spiral Concentrators. A complete range of spirals for minerals concentrationAs the most simple gravity separation technology, and arguably the most efficient, spiral concentrators hav. long played an important role in minerals processing. The spiral concentrator is one of the most effective, ow-cost devices for the gravity beneficiation of ores ...
The spiral chute and spiral concentrator for alluvial gold are both spiral chute beneficiation equipment. The structure of the spiral concentrator is shown in Figure 3-5. It is made by bending a chute around a vertical axis into a spiral shape. The spiral has 3 to 5 turns and is fixed on vertical support.
Multotec spiral concentrators segregate iron ore, chrome, mineral sands and other high-density mineral particles in sizes of less than 1.5 to 0.04 mm. Multotec's HX3, HX5 and SC mineral spiral concentrator ranges are comprised of modular housing frames consisting of two spiral assemblies. These spiral concentrators can be fully dismantled for ...

Spiral Chute is working under the the force of water flow, gravity, inertial centrifuge and friction. Slurry is pumped to the top of the spiral, and it enters a feed distributor that evenly distributes the feed to each spiral concentrator. The design and shape of the spiral make it work, when combined with gravitational acceleration.
