Definition of Wilfley table

Long-established and widely used form of shaking table; rectangular; mounted horizontally and can be sloped about its long axis. It is covered with linoleum (occasionally rubber) and has longitudinal riffles tapering at the discharge end to a smooth cleaning area, triangular in the upper corner. A compound eccentric is used to create a gentle and rapid throwing motion on the table, longitudinally. Sands, usually classified for size range, are fed continuously and worked along the table with (1) the aid of feedwater, and (2) across riffles downslope by gravity tilt adjustment and added wash water. At the discharge end, the sands have separated into bands: the heaviest and smallest uppermost; the largest and lightest lowest. The Dodd, Cammet, Hallett, and Woodbury are similar types of tables.
