Spiral Concentrator - Metso Outotec

The plumbing to each spiral concentrator should be routinely inspected to insure that no plugging or excessive wear has occurred. Splitter positioning. Efficient concentration depends on proper selection of draw-off ports and the splitter openings used. Heavy minerals such as ilmenite or hematite settle out rapidly in a spiral concentrator and they should be removed as soon as a good wide band ...

Spiral Concentrator Henan Deya Machinery Co., Ltd.

18/06/2015  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 sometimes used. For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm3; and because the separation is dependent upon

Spiral (Concentrators) - an overview ScienceDirect Topics

Spiral concentrator is a modern high-capacity and a low-cost device. It is developed for concentration of LGOs and industrial minerals in slurry form. It works on a combination of the solid particle density and its hydrodynamic dragging properties. Spirals consist of a single or double helical conduit or sluice wrapped around a central collection column. It has a wash water channel and a ...

PARTICLE FLOW MODELLING ON SPIRAL CONCENTRATORS:

Spiral concentrators, used globally in the mineral processing industry, consist of an open trough that twists downward in helix configuration about a central axis. Particles fed to the top of the concentrator are separated radially on the basis of density and size as the slurry gravitates downward. To improve performance, CFD studies validated against experimental programs have been performed ...

Of the gravity separation processes, the spiral concentrators and circular jigs are two of the most economical due to their simplicity and use of space. They operate by flowing film separation and can either use washwater or be washwater-less. The washwater spirals separate particles more easily but can have issues with entrainment of gangue with the concentrate produced. Froth flotation ...
