The Vibra Screw Versi (Variable-Speed) Feeder is the first volumetric feeder with a modular design, enabling a single unit to adapt to the broadest range of feeding applications.  The Versi Feeder is a machine for the precision metering of dry particulate materials.  The feeder can be furnished or easily modified in the field, in any of the following three configurations: 1) As a standard non-vibrated feeder consisting of a static hopper, trough and feed screw to meter free-flowing materials; 2) With the addition of a conditioning screw to the standard non-vibrated feeder assembly, to meter semi-flowing materials; and 3) With the addition of a vibrator to the standard non-vibrated feeder assembly, to meter non-free flowing materials.  In light of these options, the Vibra Screw engineering department will initially recommend a specific configuration for your application.  A careful analysis is made of your application derived from a database of more than 10,000 feeder tests and supplemented with additional testing in our laboratories, if requested.  Six different screw sizes that can provide accurate feeding up to 600 cubic feet per hour can be purchased from the manufacturer.
