ABSTRACT:
A feed prestratification attachment for classifying materials is configured to be secured to a vibrating screen unit so as to encourage stratification and more even distribution of the incoming feed material. The attachment includes a pair of side adapter plates separated by a horizontal mounting bar and a plurality of elongate rods affixed at one end to the mounting bar, the rods dimensioned so that the vibratory movement of the vibrating screen causes the rods to oscillate, thus permitting the rapid passage of undersize particles through the rods and the presentation of those particles to the screen, and enhancing the stratification of near-size and oversize particles.
