Spiral Concentrator Multotec - Multotec Mineral Processing
Spiral concentrators are simple low energy-consuming devices used for mineral separation mainly on the basis of density or by shape. Spirals are widely used in mineral processing as a method for pre-concentration and have proven to be metallurgically efficient and cost-effective.

Spiral (Concentrators) - an overview ScienceDirect Topics
The spiral concentrator is a modern high-capacity and low-cost device. It is developed for concentration of low-grade ores and industrial minerals in slurry form. It works on a combination of solid particle density and its hydrodynamic dragging properties.

Spiral Concentrators - Mine Engineer.Com
2015-8-9 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

A simple process control model for T spiral concentrators
2009-8-26 Large mineral processing plants consist of hundreds of spiral concen- trators, and the adjustment of splitters is time consuming, impractical and is in many cases neglected. Spiral splitter adjustment has up to now been the only means to adjust recovery into the concentrate, middling, tailings and (in some cases) the slimes streams.

2014-10-15 Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992). The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottiswood, 1995, Burt, 1984, Bouchard, 2001). The spirals operate on both particle size and density which make their
