Decanter centrifuge Wikipedia

Operating principle. The operating principle of a decanter centrifuge is based on separation via buoyancy.Naturally, a component with a higher density would fall to the bottom of a mixture, while the less dense component would be suspended above it. A decanter centrifuge increases the rate of settling through the use of continuous rotation, producing a g-force equivalent to
