RMSRoss's variablepitch sluice can be adjusted to tailor the slope to the individual site conditions. A previous article (EMJ, November 2012, pp. 54–58) on the use of gravity separation systems ended with the comment: "Gravity separation is clearly still a valuable component in the mineral processing toolkit and, as new applications are identified within the noncoal sector, its niche ...
amounts of material with the separation specific The complexity of coal increases as coal and ash are more evenly distributed. The higher the amount of material near the separation specific gravity, the more difficult it becomes to separate coal from ash. The most commonly used separation specific gravity is to
Sep 21, 2012· rock and coal density separation. As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any sizereduction requirements, including quarry, aggregate, grinding production and complete plant. We also supply individual crushers and mills as well as spare parts of them.
Gravity Separation. To effect the gravity separation of coal and mineral matter, 500 g crushed coal (6 mm χ 0) were added to 2000 ml tetrachloroethylene (specific gravity = ) in a large beaker placed in a well ventilated hood. The mixture was stirred by hand to insure wetting of all particles, an d then it was allow ed to stand for 30 min.
Gravity Separation Specific gravity ranges SG1: < ρ SG2: < ρ< SG3: < ρ< SG4: ρ> Size Separation Seven size ranges Largest cut: PS1 > 600 µm Smallest cut: PS7 < 75 µm
The curves show that generally significant trace element reductions would occur at a specific gravity of separation of at clean coal recoveries ranging up to 89 percent for the coals from Arizona and Wyoming, compared with specific gravity of separation with a clean coal recovery of 82 percent for the coal from New Mexico.

(14) The specific gravity of coarse coal refuse normally ranges from to for bituminous coal refuse and from to for anthracite coal refuse. The specific gravity is directly proportional to the plasticity index of the refuse. As the plasticity index increases, the specific gravity also increases.
In the separation step, the liberated particles are classified into the appropriate groups of coal, impurities, and middlings. Since impurities are generally heavier than middlings and middlings heavier than coal, the methods most commonly used to separate the input stream into the three product streams are based on gravity concentration.
