Gravity Separator Operating Instructions Manual

To effect a separation on any gravity separator, the same principles apply. Once they are understood, it isusually a simple step to adjust a gravity separator to produce optimum separation. The term "GravitySeparator" is a contraction of the proper name "Specific- Gravity Separator," which means, a separator of particles differing in their specific gravities.

Gravity Separation: A Separation Free of Charge!

Gravity separation is based on the falling velocity of a heavier phase in dispersed mode, or the rising velocity of a lighter phase in dispersed mode. The schematics below show this phenomenon in a static continuous phase. The heavier dispersed phase begins to drop with an acceleration but soon slows to a constant velocity, u t. In practice, this dropping is influenced by other forces caused ...

A class of gravity separation unit operations in ore-dressing relies for its opera­ tion on the production of a stratified bed. Heavier material gravitates downwards, and separation is achieved by splitting the ore horizontally, with the recovery of a dense stream and a lighter stream. The important ore-dressing unit operations that fall in this class are the jig, the Reichert cone and the ...

Gravity concentration - Webs

gravity separation is relatively easy, the efficiency of separation decreasing as the value of the quotient decreases. The motion of a particle in a fluid is depen- dent not only on its specific gravity, but also on its size (Chapter 9); large particles will be affected more than smaller ones. The efficiency of gravity processes therefore increases with particle size, and . 226 Wills' Mineral ...
