Spiral Concentrator | Multotec - Multotec | Mineral
Spiral Separators for heavy minerals. Our gravity separators for heavy mineral applications, including iron ore, chrome, mineral sands and other high density minerals, separate particles in the size range 2 to 0.04 mm. We have a range of spirals, from 3 to 12 turns, with high-, medium- and low-gradient profiles.
Spiral Concentrators — IMSC Group
The spiral concentrator is one of the most effective, low-cost devices for the gravity beneficiation of ores. Manufactured from lightweight, corrosion and abrasion resistant materials, spirals require a minimum of maintenance and upkeep. Spiral concentrators offer a relatively simple unit operation that translates to low capital and operating cost.

2020-3-19 · 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.
