coal spiral separateor

Our spiral separators have a diameter of +/- 950 mm. Gravity Separators for coal. Our single- and double-stage spiral separators are optimised for coal particles in the size range of 1 to 0.1 mm, providing enhanced coal washing for slurries. Their compact, modular design provides flexibility when building or upgrading your plant

    Performance Evaluation of Spiral Separator for Coal

    Spiral separator is considered to be the most effective gravity separator, capable of processing a wide range of minerals such as coal, iron, chromite, gold, zircon and other heavy minerals ores. Combined action of gravity, hydrodynamic forces and the centrifugal forces that act on the solid particles, causes the stratification of gangue and

    The spirals exhibit one of the most complex flow regimes among gravity separators used in mineral /coal processing operations. Spiral concentrator flows possess a free-surface, have shallow depths of 10 mm typically, and display laminar to increasingly turbulent behavior radially outwards with velocities reaching 3 m/s [3-6]

    The Effect of Feed Rate on the Performance of Coal Spirals

    Abstract. The flow profile on spiral separators alters with feed rate and this affects the performance of coal spirals in a different way from mineral spirals. The effect of flow rate is examined in terms of mass and volume recovery to coal product and equations are developed for three different spirals, based on the performance recorded in 684

    Spiral separators are employed in Shade Coal Preparation Plant, PBS Coals, Inc., near Central City, Pennsylvania, to recover fine coal. The Plant processes run-of-mine coal at a rate of 600 TPH, producing about 2,500 tons of clean coal per shift. Besides spirals, the preparation plant flow sheet consists of a heavy medium vessel, heavy
