Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all...

Gravity separation - RSP America

Gravity separation. The material and conveying medium are separated due to the fact that the gravitational force on the particles to be separated is greater than the energy of the carrier medium. With RSP suction excavators, this takes place by slowing down the air in the collecting tank and by diverting the flow direction.
