Abstract
A screening apparatus comprising a body, a drive system for imparting vibrations to the body, and screen media that is coupled to the body by a resilient coupling mechanism that allows oscillatory movement of the screen media with respect to the body. In response to vibration of the body, the resilient coupling mechanism causes the screen media to oscillate in a manner that is amplified with respect to the vibration of the body. The amplification may depend on the frequency of the vibrations of the body and/or on the mass of any material gathered on the screen media.
