Screw Press Dewatering System
A robust, cost-effective alternative to thermal heaters. Our screw press system efficiently extracts moisture from PE films, pulp, and wastewater, delivering outstanding dryness with minimal energy consumption.
Why Choose Our Screw Press?
Engineered to outperform traditional drying methods, our system combines durability, efficiency, and versatility into one powerful unit.
Superior Moisture Removal
Reliably reduces moisture content to below 15%, ensuring your material is perfectly prepared for downstream thermal drying or pelletizing.
Energy Efficient
Utilizes purely mechanical pressure to squeeze out water, offering massive energy savings compared to energy-intensive thermal heating systems.
Versatile Application
Proven reliability across multiple industries, including plastic recycling (PE films), food processing waste, and paper & pulp sludge.
The Ingenious Principle
A progressive compression design ensures gentle yet effective dewatering.
Feeding
Wet material enters via the vertical feeder where the screw shaft is at its narrowest diameter.
Compression
As the shaft rotates, its diameter increases, gradually compressing the material against the perforated outer casing.
Discharge
Water is squeezed out through fine perforations, while the dried plastic exits a narrow, precision-engineered gap.
Precision Engineering
The robust outer casing features thousands of meticulously drilled perforations. These allow water to drain freely while retaining solid materials, even under high pressure. The variable-pitch screw shaft is designed to prevent clogging while maximizing throughput.

Frequently Asked Questions
What is the typical output moisture content?
For most soft plastics like PE films, the system can reliably reduce moisture content to below 15%. This is an ideal level for feeding into a subsequent thermal drying system or agglomerator.
How does this compare to a centrifugal dryer?
Screw presses apply much higher pressure and are generally more effective for materials that hold water stubbornly, like thin films or sludge. They run at lower speeds, resulting in less noise and lower maintenance compared to high-speed centrifugal dryers.
Can the machine length be customized?
Yes. While our standard industrial units range from 4 to 6 meters, we can customize the screw length and diameter to match your specific facility layout and throughput capacity requirements.
Is the machine easy to maintain?
Absolutely. The slow rotational speed means less wear and tear on components. The perforated casing is designed for self-cleaning or easy external cleaning, and the robust gearbox requires only standard periodic maintenance.
