ABSTRACT:
Opposite ends of a dry vibration-fluidized separator are moved with complex vibrations, including linear, whirl, linear plus whirl, oscillation, linear plus oscillation, pitch and roll. Near zero to large amplitudes up to about ±0.050 inches and low frequencies of about 30 Hz are used. Mixed particulate materials are fed into a first end and circulate across and along the separator in a shallow depth. More dense materials move linearly along a floor and are removed through an opening in a second end of the floor. The less dense materials flow over a weir at the second end of the separator.
