VIBRATORY SCREEN SEPARATOR

摘要

A vibratory screen separator having a resiliently mounted frame (30) with a screen mounting to receive screens for material flow thereacross. Eccentric weight systems are rotationally mounted with effective axes (36, 42, 44) of eccentric force coincident. The weight systems are symmetrical about a center plane through the separator for uniform vibration thereacross. The coincident axes extend through the center of gravity. A drive is coupled with both weight systems such that the direction of rotation of the weight systems is opposite to one another in one embodiment and opposite in another.
