Simulation of particle-laden flow in a Humphrey spiral concentrator
The Humphrey spiral concentrator (HSC) is a widely used mineral separator that sorts particles on the basis of differences in the specific gravities of particles. Since its invention by Ira. B. Humphrey in the 1940s, HSCs have been used over decades in both mineral and coal industry, given their advantages such as low cost, long life, and Simulation of particle-laden flow in a Humphrey spiral concentrator using dust-liquid smoothed particle hydrodynamics.

Principles of spiral concentration. Int. J. Miner. Process., 15: 173--181. The different stages of the mechanism of concentration in spiral concentrators are dis- cussed. The significance of many design and operational variables and their interrelation- ships are examined. The various areas where the spiral concentrators are applicable areThe 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.A comparative study of trough profile and operating

Principles of spiral concentration ScienceDirect
A comprehensive numerical analysis of the fluid flow and dilute particulate flow in the LD9 spiral separator is presented in this work. The air–water flow field on a coal spiral is simulated using the volume of fluid (VOF) coupled with RANS turbulence models. Water depth and flow field predictions by RSM show close agreement with experiments.The spiral classifier, recently, has emerged as the most effective gravity separator since its introduction. The spiral separator also known as spiral concentrator, continues to be the most effective gravity separator, useful in processing a wide variety of minerals such as coal, iron, chromite, gold, zircon and other heavy minerals ores [1, Performance Evaluation of Spiral Separator for Coal Cleaning

Spiral concentrators are gravity based separation devices used for the preparation of coal, iron and other heavy minerals ores (Wills, 1992). The classification of the particles in spirals is based on the combination of gravity, centrifuge, drag and Bagnold forces (Atasoy and Spottiswood, 1995, Burt, 1984, Bouchard, 2001).Humphrey spiral chute sprial separator JXWKD mining equipment for sale laboratory spiral concentrator $1,200.00 $1,500.00.
