Coal Gravity Separation How It Works. Coal washing involves grinding the coal into smaller pieces and passing it through a process called gravity separation. One technique involves feeding the coal into barrels containing a fluid that has a density which causes the coal to float, while unwanted material sinks and is removed from the fuel mix

The separation by gravity is based on the difference in settling rates or terminal velocities of particles of different density and size. However, with short distances of travel in some separation processes, particles may not have a chance to reach their terminal velocity.
The Separation Process: How a Gravity Separator Works Stratification From an inlet with an adjustable feed rate, the material is fed onto the gravity separator's inclined reciprocating grading deck, which normally has a special woven wire mesh surface, except for extremely fine products, when a specialist fabric deck is used. ... Check. coal ...
Separation efficiency of coal cleaning equipment is most commonly assessed by the following parameters. Tromp curves, also known as partition curves and distribution curves, which compare the ideal and actual separation curves and the difference, if any, arising between the two curves known as Error Area
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force. One type of gravity separator lifts the material by vacuum over an inclined vibrating screen covered deck. This results in the …

In the case of coal, efficient separations have been achieved down to particle sizes of 325 mesh and finer. These units are particularly well-suited for pyritic sulfur removal because of the large density difference between pyrite and coal.
Separation is enhanced by the differences in centrifugal forces between the two: the lighter, faster flowing material is forced outward towards the surface, and the heavier, slower material remains inward towards the bottom.

How Gravity Separation Tables Work. The gravity separation table, or air table, is commonly used to separate particles by weight and density. A separation table can be used for any dry material as it moves on a "fluidized" bed of air across the table.The separator creates eccentric motion and has an adjustable uphill tilt which separates heavier particles from lighter particles.
