Screw Press Separator

Screw Press Separator: Industrial Solid-Liquid Separation System

Dewatering high-volume cattle waste or industrial slurry requires 24/7 reliability. The Yuxing Screw Press Separator Model YXXSFL-1500 offers efficient separation with a 40-50m³/h processing capacity and a small size of 2600×1410×1505mm.

This inclined screen separator turns pig manure slurry and other high-moisture materials into stackable solids and pumpable liquid fractions using a 5.5kW main unit at 56rpm. Yuxing has improved every component—from the wedge-wire screen to the helical screw—to maximise uptime in difficult agricultural and industrial conditions after 20 years of field experience in 50+ countries.

The system uses 380V electricity and a 3kW water pump to produce 25-40% dry matter solids, lowering storage capacity and disposal costs while recovering organic material for composting or bedding reuse.

How It Works

When raw slurry enters the feed hopper, a high-torque helical screw drives it through a cylindrical wedge-wire screen to separate it.

Screw rotation at 56rpm delivers increasing mechanical pressure on material. The precision-calibrated screen apertures drive liquids radially outward while compressing and transporting particles to the discharge end.

An adjustable weighted flap at the exit regulates back-pressure, letting you modify solid fraction moisture. Lower resistance speeds throughput, higher resistance dries cakes. This continuous extrusion cycle without batch interruptions makes it perfect for automated waste management operations.

Self-cleaning internal screw minimises screen blinding, and inclined structure allows gravity to drain liquid, saving energy and mechanical wear.

Technical Specifications

Key Applications Across Industries

This solution addresses major dewatering issues in numerous industries.

Livestock farming: Large dairy and swine enterprises utilise it to separate fresh manure into reusable cow bedding and nutrient-rich liquid fertiliser, saving up to 60% on bedding costs and lagoon volumes.

Streamlined digestate processing using biogas plants. By reducing digestate volume by 40-50%, the separator produces high-quality solid compost for field spreading and a liquid fraction for irrigation or treatment.

Beer, pulp, and vegetable processors use the method to dewater wasted grains, fibrous wastes, and organic sludge. Resource recovery and vastly decreased disposal costs transform garbage into cash.

All applications benefit from the system's capacity to handle high-solid concentrations and abrasive materials without performance loss, even under 24-hour operation.

Engineering Advantages & Quality Standards

Yuxing uses materials and components proven in tough manufacturing settings to make every Screw Press Separator.

AISI 304 stainless steel housing and screen cage resist acidic manure and chemicals.

When processing sand-laden or grit-containing slurries, the helical screw's HRC-tested harder edges provide durability.

Precision Screen Design: Wedge-wire screen apertures' regular pressure distribution prevents premature wear and maintains separation efficiency over time.

Energy Efficiency: At 5.5kW for the main unit and 3kW for the feed pump, the system reduces operational expenses per cubic metre processed.

All equipment meets ISO 9001 and CE safety requirements. Hydrostatic pressure testing verifies structural integrity under maximum back-pressure, while dynamic balancing testing eliminates vibrations.

FAQ

Q: What is the maximum dry matter content achievable?

A: Depending on your input material's fiber structure, the separator typically achieves 25-40% dry matter content, verified through standard oven-dry testing protocols.

Q: How often does the screen need replacing?

A: With proper maintenance and hardened stainless steel construction, screens last 12-24 months in standard manure applications before gap widening affects performance.

Q: Can the system handle oily or greasy materials?

A: Yes. For high-fat feedstocks like food processing waste, Yuxing specifies screen configurations and hot-water flushing systems to prevent lipid buildup and maintain throughput.

Q: How do you adjust the dryness of discharged solids?

A: Simply reposition the weighted pressure flap at the discharge outlet. Increased weight creates higher back-pressure for drier cakes; reduced weight maintains faster flow.

Q: Is the system prone to clogging?

A: No. The continuous screw rotation provides self-cleaning action against the screen. For sticky or high-protein slurries, Yuxing recommends an optional internal brush system for maximum reliability.
