Screw Press SP

Screenings Press – Continuous Dewatering, Compaction, and Conveying of Screenings

Function and Design

The screenings press is used for the continuous dewatering, compaction, and conveying of screenings. Conveying is achieved by means of an extremely robust conveying and pressing spiral with a length of up to 10 m. The conveying spiral ends in a pressing zone enclosed by a perforated pressing pipe.
With the help of a counter-pressure cone at the end and a conveying spiral that extends only partially into the pressing pipe, the conveyed material forms a friction plug and is compacted while being dewatered.

The pushing drive unit, the shaftless spiral, and the open spiral end ensure clog-free operation.

To reduce wear and extend the service life of the spiral, a plastic wear liner is installed between the stainless steel U-trough and the spiral.

Dewatering Zones and Hygiene
The pre-dewatering zones located along the conveying section of the screw press (e.g., beneath the screen inlets), as well as the dewatering zone at the drive end to protect the bearing and drive unit, are designed in such a way that no brushes or other additional cleaning elements are required, eliminating the need for frequent maintenance and replacements.
For hygienic reasons, the entire length of the machine is covered with bolted lids, except in the area of the feed hopper.
