ABSTRACT:
An electro-static tobacco separator is provided in which fine tobacco particles are separated from sand particles by passing the mixture along a vibratory conveyor wherein a voltage is impressed across the conveyor and a grid disposed above the conveyor. The lighter tobacco particles are attracted by the oppositely charged grid and passed upwardly into a separate trough which is also vibrated, so that the tobacco particles and sand are separately discharged at the discharge end of the conveyor.
