WSG Screw Compactor

WSG Screw Compactors are designed for long-life and ease of maintenance. Each Screw Compactor significantly decreases volume, increases solids content and reduces the overall weight of the screenings. An optional wash module can be utilized to reduce organics. The compacted screenings conform to EPA paint filter testing requirements for dryness and the components used in the design meet CEMA standards.

Screenings are introduced to the compactor via an inlet hopper assembly. While the internal screw rotates, the material is dewatered as it is moved across the perforated plate zone and into the support and compacting zone, where gravity and surface friction react to force additional water from the screenings. The resulting compacted plug is then conveyed out of the discharge of the screw.

The internal screw conveyor is closely fitted to an adjustable perforated plate zone, to aid in effective cleaning, screenings transfer and compaction. The perforated zone is fully housed in a 10-gauge formed stainless steel sheet metal drain pan assembly. Inlet hoppers and supports can be made to fit most headworks configurations.
