Product Overview
The standard screw conveyor is a versatile mechanical handling system designed for efficient bulk material transfer across industries such as agriculture, food processing, chemical manufacturing, mining, and construction. Engineered for reliability and durability, it excels in transporting powders, granules, pellets, and semi-fluid materials horizontally or at slight inclinations (up to 20°). Its modular design allows customization to meet diverse operational needs, making it ideal for applications requiring controlled feeding, mixing, or metering.
Key Features & Benefits
- Robust Construction
- Trough & Housing: Fabricated from high-grade carbon steel or stainless steel (SS304/SS316) for corrosion resistance and longevity.
- Screw Blade: Precision-formed helical blades with thicknesses compliant with GB/T standards (see Table 1).
- Shaft & Bearings: Heavy-duty steel shaft supported by anti-friction bearings and intermediate hanger bearings for smooth operation.
- Optimized Performance
- Low Maintenance: Sealed design minimizes dust leakage; replaceable wear-resistant liners extend service life.
- Energy Efficiency: Balanced power consumption aligns with calculated drive power (per GB/T 36865-2018 Appendix B).
- Flexible Configuration: Supports multiple inlet/outlet points, variable screw pitches, and custom lengths (up to 50m).
- Compliance & Safety
- Fully compliant with GB/T standards for welding (uniform, crack-free seams), assembly, and surface treatment.
- Optional explosion-proof motors and grounding systems for hazardous environments.
