Mar 26, 2016 · Spiral concentrators are capable of sustained recoveries of heavy minerals in the size range of 3 mm down to 75 microns (6 to 200 mesh). They are suitable for use as roughers, cleaners, or scavengers. Feed rates may vary from 0.5 to 4 tons per hour per start, depending on the size, shape, and density of the valuable material
In a spiral, heavy mineral concentrate is selectively directed into the spiral trough near the inside of the spiral surface through the use of adjustable product splitters. The concentrate then flows through product discharge outlet ports down the length of the helix
Spiral concentrators are normally used in banks of multiple spirals. Typical capacities for spirals run from 1-3 tons per hour of feed for minerals and 3-5 tons per hour for coal. Typical construction of a spiral concentrator is fiberglass and urethane to reduce wear from abrasion. Charles Kubach, Mining and Mineral Processing Engineer
The fine mineral spiral series is used for fine feed with particles in the range of 30-150 microns: WW Series: Utilises wash water addition for enhanced grade control in specific applications (i.e. iron ore, mineral sand) HC Series: These super-high capacity spirals have been designed specifically for more economical and compact high tonnage plants

The centrifugal concentrator rotates at a high speed, generating a high “G” force, which can separate small gravity recovery gold (less than 50 microns), which was of previously unrecoverable with traditional mineral jigs, spiral separator, and gravity tables. In recent years, the application of centrifugal force has proved to be an
Spiral separator(spiral chute) is one of the gravity concentrators. It can separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. In the processing of ores, spiral …
Jun 18, 2015 · Typical spiral concentrators will use a slurry from about 20%-40% solids by weight, with a particle size somewhere between 1.5-.075 mm (17-340 mesh), though somewhat larger particle sizes are …
