  • Coal breaker - The Full Wiki

    Coal jigs separated coal from impurities by using gravity. Since the relative density of uniformly sized pieces of coal, slate, ash, dirt, and sulphur vary, pieces of each element will descend through water at different speeds—allowing them to be separated. [3] Some examples of coal jigs from the beginning of the 20th century include:

    The APIC Jig is a gravity separator which separates particles of different densities in a homogeneous bed of solid material. Valuable products can thus be separated from waste material, effectively producing clean, saleable products.

  • Gravity Concentration By Jigs Engineering Essay

    The jig is normally used to concentrate relatively coarse material. Good separation is possible if the feed is closely sized (e.g. 3 – 10) and if the sp. gr. difference is large. Many large jig circuits are still operated in the coal, cassiteriite, tungsten, gold, barytes and iron-ore industries.

    One is the effect of hindered settling meaning that a heavier particle will settle faster than a light particle. The other one is the separation process in an upward flow of water which will separate the particles by their density. These two actions are combined in a Jig by slurry pulses generated mechanically or by air. Coal Jigs (Baum type)

    a) Jigs: The methods operate by differences in specific gravity. Jigs rely on stratification in a bed of coal when the carrying water is pulsed. The shale tends to sin, and the cleaner coal rises. The basic jig, Baum Jig, is suitable for larger feed sizes. Although the Baum Jig can clean a wide range of coal sizes, it is most effective at 10-35 mm.
