Shaker Table Operating Principles The most generally accepted explanation of the action of a concentrating shaker table is that as the material to be treated is fanned out over the shaker table deck by the differential motion and gravitational flow, the particles become stratified in layers behind the riffl This stratificaton is followed by the removal of successive layers from the top .
