Characteristics analysis of horizontal spiral discharge settling centrifuge

1. Continuous Separation

No need to stop for discharge: The screw conveyor and the bowl rotate in the same direction at a differential speed, enabling continuous solid-liquid separation and solids discharge. Suitable for large-scale industrial production.

Large processing capacity: Single-machine throughput ranges from 1 to 100 m³/h, particularly suitable for high-concentration suspensions (solid content 10%–40%).

2. Compact Structure, Stable Operation
Horizontal design: Small footprint and flexible installation, suitable for space-constrained sites.

Fully enclosed structure: Prevents material leakage or contamination, meeting environmental protection and clean production requirements (e.g., food and pharmaceutical industries).

3. High Separation Precision

High centrifugal force: Separation factor up to 3000–5000, capable of separating fine particles with a diameter ≥5 μm.

Flexible adjustment: Parameters such as bowl speed and differential speed can be adjusted to suit different material characteristics (e.g., density difference, viscosity).

4. Wide Applicability

Multi-industry applications:

• Environmental protection: municipal/industrial sludge dewatering, river dredging.
• Chemical/mining: catalyst recovery, mineral classification.
• Food and pharmaceutical: starch extraction, fermentation biomass separation.

Corrosion-resistant design: Materials can be selected from stainless steel, titanium alloy, or plastic-lined, suitable for harsh conditions such as acid/alkali and high temperature.

5. Low Maintenance Cost
Modular design: Key components (e.g., screw flights, bearings) are easy to disassemble and maintain, reducing downtime.

Energy optimization: Compared with batch-type centrifuges, energy consumption per unit of throughput is reduced by 30%–50%.

6. Limitations

Material adaptability: Sensitive to solid particle hardness and fiber content; in extreme cases, screw clogging may occur.

High initial investment: Equipment cost is higher than some traditional separation devices (e.g., plate-and-frame filter presses), but long-term operational economics are better.
