Read MoreNorway is globally recognized for its strict environmental regulations, high labor costs, and commitment to sustainable industrial practices. As a result, Norwegian industries demand dewatering and separation technologies that are not only highly efficient but also automated, energy-saving, and exceptionally durable.
The Single Screw Press has emerged as a cornerstone technology across several key Norwegian sectors:
Achieve up to 35-45% dry cake solids depending on the feed material, significantly lowering downstream thermal drying costs.
Low rotational speed (typically 1-5 RPM) ensures minimal wear, low noise levels, and continuous, unattended operation.
Engineered for extreme durability, corrosion resistance, and optimal separation efficiency.
At Jiangsu Zongheng Concentrating and Drying Equipment Co., Ltd, we design our single screw presses with a deep understanding of mechanical shear, filtration dynamics, and material science. For the Norwegian market, where marine environments and corrosive process fluids are common, we offer customized metallurgical and structural configurations.
Standard carbon steels or basic stainless steels fail rapidly in aquaculture (high salinity) and chemical processing. We manufacture our screw shafts and screen baskets using premium Duplex Stainless Steel (SAF 2205 / 1.4462) or Super 316L. This provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich environments.
The volume between the screw flights decreases progressively from the feed inlet to the discharge end. This is achieved through a combination of a tapered screw shaft and decreasing pitch. As the material is conveyed forward, the volume reduces, generating a gentle yet powerful mechanical pressure that forces liquid out through the screen basket without shearing the solids.
Our screen baskets feature a non-clogging wedge wire profile. The V-shaped opening widens inward, ensuring that particles close to the slot size do not get trapped. Slot widths are customized from 0.1 mm to 2.0 mm based on laboratory testing of your specific sludge or slurry sample.
Unlike standard municipal screw presses, our industrial-grade single screw press features an adjustable pneumatic backpressure cone at the discharge outlet. This system dynamically responds to changes in feed consistency, maintaining constant pressure inside the press to guarantee uniform cake dryness even if the feed flow rate fluctuates.
Over three decades of engineering excellence, delivering high-capacity industrial systems worldwide.
In modern process engineering, a single piece of equipment rarely operates in isolation. To achieve true sustainability and energy efficiency, Norwegian plants require integrated, macro-level process solutions.
Jiangsu Zongheng specializes in combining mechanical separation with thermal concentration. In a typical fish meal or industrial wastewater application, the process flow is optimized as follows:
This integrated approach achieves Zero Liquid Discharge (ZLD), maximizes resource recovery, and reduces carbon footprint—aligning perfectly with Norway's green transition goals.
Pioneering the next generation of smart, AI-driven dewatering systems for the Nordic region.
Integration of real-time torque sensors, vibration transmitters, and moisture analyzers. Our systems feed data directly to your centralized SCADA control room, predicting maintenance needs before downtime occurs.
Optimizing motor efficiency using IE4/IE5 variable frequency drives (VFDs). By reducing the mechanical energy required per ton of dewatered material, we help Norwegian operators lower their Scope 2 emissions.
Redesigning screen geometries to handle delicate organic matrices, such as macroalgae (seaweed) and insect protein, supporting Norway's emerging bio-marine economy.
Importing industrial machinery into Norway requires strict adherence to local and European standards. Jiangsu Zongheng guarantees complete compliance and seamless integration:

When processing non-abrasive organic materials like fish waste or pulp sludge, our Duplex Stainless Steel screen baskets and hard-faced screw flights typically last between 3 to 5 years under continuous 24/7 operation. For abrasive materials, we apply tungsten carbide coating to the flight edges to significantly extend service life.
Our presses are equipped with an automated pneumatic backpressure cone at the discharge end. Controlled by a proportional valve linked to the main drive motor's torque sensor, the cone automatically adjusts its position to maintain constant internal pressure, ensuring consistent cake dryness even if the feed concentration varies.
For fibrous materials (like pulp rejects or fish silage), mechanical dewatering can often be achieved without polymer addition. However, for biological or municipal wastewater sludges containing fine colloidal particles, flocculant (polymer) dosing is highly recommended to capture fines, maximize filtrate clarity, and achieve optimal cake dryness.
Yes. For offshore, marine, or coastal installations in Norway, we customize the metallurgy to Super Duplex Stainless Steel or high-molybdenum alloys, and apply marine-grade epoxy coatings to non-wetted carbon steel parts (such as the main frame and gearbox casing) to resist salt spray and harsh marine climates.
The standard engineering and manufacturing cycle for a customized single screw press is 12 to 16 weeks, depending on the size and material specifications. This includes rigorous factory acceptance testing (FAT) before shipment.
