Wastewater Treatment Technology | Global Environmental Solutions for Cost-Effective Pollution Control
The main motor drives the drum to full-speed rotation. Material is continuously fed through the inlet pipe into the screw conveyor and evenly distributed to the discharge ports. Under centrifugal force, solids settle against the drum wall and are pushed by the screw toward the conical end for discharge, while liquids overflow from the large-end weir ports, achieving "solids-out-from-small-end, liquids-out-from-large-end" separation. This process effectively isolates solid particles from liquids or separates two immiscible liquids with different specific gravities.
I. Key Features of Three-Phase Decanter Centrifuges
Designed for clarifying, separating, dewatering particles (0.002–3 mm) or classifying fine solids (1 μm–5 μm), these centrifuges offer wide applicability, continuous operation, high throughput, low cost, and easy maintenance, making them ideal for solid-liquid separation in:
- Chemical | Light Industry | Pharmaceuticals
- Food Processing | Paper Manufacturing | Mining
Technical Advantages:
- High-Precision Differential: Compact structure with smooth operation and enhanced safety.
- Premium Bearings: Imported main bearings ensure operational accuracy and user-friendly control.
- Corrosion-Resistant Construction: All material-contact parts use high-grade stainless steel.
- Multi-Level Safety Protections: Overload safeguards for fail-safe production.
- Flexible Configurations: Standard or explosion-proof models for diverse needs.
- Optimized Drum Design: High length-to-diameter ratio, variable speeds, and adjustable cone angles.
- Wear-Resistant Screw: Hard alloy surfacing extends service life in abrasive applications.
- Adaptable Frame: Low-center-of-gravity, high-support, or mobile designs available.
