Oct 31, 2019· Gravity separation is a method of separating a suspension into its individual components It is commonly used in medical settings to separate red blood cells from plasma, and in metallurgical industries to separate particles of different metalsEffective separation relies upon the different densities and sizes of the particulate matter, and works by combining forces of gravity with resistance .
The closer you are, the stronger the gravity Why is gravity important? Gravity is very important to our everyday liv Without Earth's gravity we would fly right off it We'd all have to be strapped down If you kicked a ball, it would fly off forever While it might be fun to try for a few minutes, we certainly couldn't live without gravity
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 →
