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 the pulp …

 — The secondary circulation in a spiral concentrator had been explained in an earlier publication with the help of classical solid mechanics. In the present paper, classical solid mechanics has again been applied to develop simplified flow equations for fluid and slurry systems specific to the spiral concentrator. A new concept of composite ...

Spiral concentrators. entrators beneficiate minerals with significant differences in specific gravity (SG). Separation is achieved by a combination of actions that include …

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.

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.
