A screening apparatus comprising screen decks set on angled support legs moveably mounted within a framework and driven by a single force adjustable link arm that is connected to a cam drive shaft. The RPM, angle of the legs and cam throw are adjustable to provide for gentler or more aggressive reciprocation of the deck. The support legs are at an angle relative to the screen deck when at rest and while working. The angled support legs at the non-drive end are independently adjustable. The drive mechanism is outside mounted. A flywheel can be integrated if needed. The apparatus is designed to aggressively separate various materials and throw the overs off the end of the screen deck. The unit could be powered by a variety of motors and be modified to attach to a variety of construction machinery or function as a stationary unit.
