PRINCIPLES OF GRAVITY SEPARATION - ir.library.msstate.edu

Gravity separators use air as a standard rather than water. Since air is lighter than water, the relative difference between particles of differing weights is widened. For this reason, the gravity separator is a very sensitive machine and when operated correctly can produce a very precise separation. The Process of Stratification

How Gravity Tables Work A gravity separator, or air table, is commonly used to separate particles by weight and density. A separation 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 … Continue reading Gravity Separation →
