Abstract:
A vibratory screen separator comprisinga resiliently mounted frame having a screen mounting extending in a first plane and defining a direction of material travel in the first plane; a first eccentric weight system rotationally mounted to the resiliently mounted frame about a first axis; a second eccentric weight system rotationally mounted to the resiliently mounted frame about a second axis coincident with the first axis, each of the first and the second eccentric weight systems being symmetrical about a center plane of the resiliently mounted frame that is parallel to the direction of material travel and normal to the first plane; a drive coupled to the first and second eccentric weight systems, the direction of rotation of the first eccentric weight system being opposite to the direction of rotation of the second eccentric weight system.
