The first unit, called the gravity unit , used narrow 6mm wide channels to perform a density separation. The overflow from this unit contained coal contaminated with fine high ash slimes. This was fed into the second unit, called the deslime unit , which used wider 12mm channels to perform a size classification to remove these slimes.

Oct 12, 2018 Fig 1 Effect of centrifugal force on gravity force. Separation of the ore particle by gravity is dependent on two factors namely (i) settling rate of the particles, and (ii) difference in specific gravity when compared against the medium in which they are being separated, this gives differential settling rate and has been termed the ‘concentration criteria’.Settling rate of a particle is.
