ABSTRACT:
A vibratory screen apparatus is described for classifying loose solid material through horizontal screens 22-24 that are vibrated in elliptical paths by two independent eccentric weight means 28 and 30. The eccentric weight means 28 and 30 are mounted on the screen frame 15 elevationally below the center of gravity of the apparatus and upstream of the center of gravity toward the feed end. Each of the eccentric weight means include adjustable weights for adjusting the "throw" of the classifier that are outboard of bearings that support shafts that extend between the sides of the frame.
