Tubular centrifuge separator is used for separating various emulsions which are difficult to separate, especially suitable for liquid-liquid separation for the two liquids with slight gravity difference and liquid-liquid-solid separation for a mixture consists of two in-miscible liquids that may contain fine suspended solids in small quantities. It is a high-speed centrifuge with strong separating capacity. The suspension is fed through the bottom, the bowl of the centrifuge rotates around its axis and forms a strong centrifugal force and the centrifugal force separates the suspension into liquids and solid.
