A screening machine that uses electrically controlled transducers to vibrate a separating screen. The transducers can be piezoelectric patches, discrete piezoelectric components, or electromagnetic shakers. Further, the transducers can be coupled directly to the screen or through a vibration amplifier. The transducers and/or amplifiers can be coupled to the screen at different attachment locations. One or more of the transducers can be used as sensors to provide feedback for operation control.
