Our screw compactors are at the heart of efficient screenings treatment systems.
They significantly reduce waste volume while optimizing dewatering. Thanks to their robustness and durability, our screws guarantee reliable operation, even under demanding conditions.
Adaptable to a variety of flow rates, they can be perfectly integrated into your facilities to maximize the profitability of your process while minimizing environmental impact. With FB Procédés screw compactors, you're opting for a high-performance, sustainable solution for waste management.
Reduction of waste volume through compaction screws.
The benefit of the compaction screw is to reduce the waste lifted by the bar screen by nearly 50% and decrease its water content by 30%.
As a result, waste collection costs are reduced, and depending on the municipalities, the screenings can be collected with household waste.
Transport or compaction screws, an ideal adaptation for our bar screens.
Regardless of the installation, the junction between the feed trough of the compaction screw and the waste discharge hopper of the bar screen is made as precise as possible. This prevents any dripping and keeps the entire system cleaner.
Finally, our compaction screws are delivered with detachable and height-adjustable "support" feet.
Easily accessible and removable parts
Whether it's the compaction cell, the compression valve, the wear strip at the bottom of the trough in the conveying area, or the washing ramps located above the waste compaction chamber, all of these parts remain easily accessible.
Control System
When our transport or compaction screws are paired with our bar screens, we systematically add a "Forward" push button on the manual control box of the screens (the "Reverse" button, which serves as a de-snagging function, remains optional).
In terms of operation, we recommend running it at the same time as the bar screen and stopping it approximately one minute after the bar screen has stopped.
Options for screw conveyors
As with the bar screens, we offer several options to optimize the operation of the compaction screw and tailor it to best suit the specific context.
- Waste washing ramp
- Solenoid valve for compaction chamber supply
- Automatic bagger, with 80-metre plastic bag refill
- Vertical waste chute
