hindered setteling and spiral concentrator

Oct 01, 1995 Bagnold forces, hindered settling , interstitial trickling and centrifugal /brces are identified as the major mechanism effective in the separation of particles in a spiral trough [3]. Among these, the Bagnold forces, being unique to spirals, have only been qualitatively applied to

    A hindered-settling fluid classifier is adapted for processing aggregate entrained in a flowing slurry. The classifier includes a classifier tank defined by walls, and having an inlet at its upstream end and an outlet at its downstream end. A slurry feed pipe is connected to the tank inlet for introducing the aggregate slurry into the classifier tank for processing

    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 to treat chromite ore in 1943. ... (Sivamohan and Forssberg 1985) ie., 1) Hindered settling 2) Interstitial trickling 3

    Particle-laden flow in a spiral separator - NASA/ADS

    Spiral concentrators are used in the mining industry to separate particles of different size or density. The existing modeling literature considers the flow as a background fluid carrying non-neutrally buoyant particles. However recent work on modeling of slurries on inclines shows that at relatively modest volume fractions of particles, the presence of the particles affects the flow and

    A hindered-settling column and a spiral concentrator were also used to process nominal 1.2 0.15-mm material. Product yields and ash contents were obtained for all tests, while partition curves were generated for selected tests from which the characteristic performance parameters (relative density of separation and probable error) were determined
