Abstract
Abstract A vibratory screen separator having an arcuate plate which receives sediment from a plurality of hydrocyclones and distributes that sediment to the separator screen. The arcuate plate collects the sediment from a plurality of discharge positions and presents it to a centrally positioned outlet where it can fall onto the separator screen. The arcuate plate is itself positioned on the vibratory screen separator and is caused to vibrate therewith. The arcuate plate in combination with a grate over the centrally positioned outlet, also provides a cover for the separator to prevent large objects from damaging the screen. A hoist system is provided which can remove the plate for service and replacement of the screen.
