Claim 5:
6. A method for separating drill cuttings from drilling fluid, the method comprising:
directing, by a receptacle positioned at a first end of a screen, a mixture of the drill cuttings and the drilling fluid onto the screen;
generating, by a plurality of acoustic transducers attached to the screen, acoustic vibrations to facilitate travel of the mixture across the screen, wherein each acoustic transducer generates acoustic vibrations at a different frequency from each other;
separating at least a portion of the drilling fluid from the drill cuttings by allowing the portion of the drilling fluid to fall through the screen via holes defined by the screen;
separating, by the acoustic vibrations of different frequencies generated by the plurality of acoustic transducers, the drill cuttings themselves based on density as the drill cuttings travel across the screen;
receiving, by a first collection pan positioned at a second end of the screen opposite the receptacle, a first portion of the drill cuttings that have traveled across the screen; and
receiving, by a second collection pan positioned at the second end of the screen opposite the receptacle, a second portion of the drill cuttings that have traveled across the screen.
