How does gravity separation work? – JanetPanic.com

How does gravity separation work? The gravity separation table, or air table, is commonly used to separate particles by weight and density. The separator creates eccentric motion and has an adjustable uphill tilt which separates heavier particles from lighter particles. As a result, light and heavy contaminants can be removed from your product.
