Hydro-Sludge™ Screen General Information
Overview
The Hydro-Sludge™ Screen is a horizontal in-line coarse material separator, comprising of four principle zones;
inlet, screening, pressing (compacting) and discharge. The feed from the inlet, enters the center of the screening
zone, where the coarse material retained on the inner surface of the perforated screen, is transported to the
pressing zone and onwards to the discharge by an Archimedean screw. Compacted coarse material (screenings)
is discharged into a suitable container, by the action of a regulated retention cone, controlled by a pneumatic
system linked the varying drive load (torque) of the drive motor.
