ABSTRACT:
A separator system may include a first trough having an inlet end, a downstream, outlet end and a trough floor, a first screen section supported in the trough spaced from the trough floor, the first screen section having a first end and a second downstream end, a material-retaining surface disposed at the downstream end of the first screen section, the material-retaining surface disposed at an angle relative to the first screen section to limit the movement of material across the first screen section, and a vibratory generator coupled to the trough. The separator system may alternatively or in addition include a gate disposed at the end of the screen section, the gate having a first position and a second position.
