Proper distribution is normally achieved using a spiral slurry feed distributor. Standard distributors divide the feed into 12, 24, 36 or 48 ways. When selecting a distributor one should be chosen which is closest to the number of spiral starts to be operated. The plumbing to each spiral concentrator should be

The spiral concentrator was deployed commercially for the first time in the year 1943 by I.B. Humphreys Jr. to concentrate the chromite bearing sands in Oregon, USA (Holtham 2006). Spirals can efficiently treat and recover valuable particles in the size range of 3 mm to 75 μm. The operation of the spiral concentrator is simple and techno ...
Spiral Concentrator; Mineral Spiral Concentrators; Mineral Spiral Concentrators. Separation of fine heavy minerals has been made easier with Multotec's ranges of mineral spiral concentrators. Our gravity concentration products separate fine heavy mineral sizes from 1.5 mm to 0.04 mm and are ideal for iron ore, chrome, mineral sands and high ...
The MG12 spiral gave us the opportunity to achieve maximum recovery from a multi-stage circuit making the plant smaller and easier to float. The spiral bank modules dropped into and integrated with the plant structure enabling a smooth construction process. It proved to be a very effective solution for a new ore body."

When the deslimed feed is fed to the spiral, high concentrate grades has been produced with very high recoveries as high as 98%. INTRODUCTION Spiral concentrator is one of the simple yet efficient methods of mineral beneficiation which sorts particles according to their specific gravity differences. First commercial spiral concentrator was used
Spiral concentrator is a gravity separation equipment, consisting of a spiral channel connected to a vertical support. Separation of particles in spirals is based on particle size and density and the combined effect of gravitational forces, centrifugal forces, drag, and Bagnold forces (forces related to Newtonian fluid) on the particles [1,2,3].As …
Our concentrator's leading-edge cone technology has been built on 40 years of innovation and is designed to capture the maximum amount of gold per cycle. Knelson is the only enhanced gravity concentrator with a fully fluidised bed allowing for upgrading throughout the entire cone surface.
Mineral Spiral Concentrators: 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.

The spiral concentrator, with the trough profile of cubic parabola in inner place and the ellipse in outer place, is more desirable to separate the coal slime used in this paper. The findings of the present study are of great importance in trough profile optimization of the spiral concentrator.
Working Principle. Spiral Separators, which are also called Spiral Concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. The heavy frictional forces slow their velocity. As a result, faster particles higher up in the flow.
