Through vertical or large-angle conveying, the floor space is only 30%-50% of that of traditional conveying equipment, making it especially suitable for workshops with limited space.
Modular design supports flexible integration into production lines (e.g., inter-floor material transfer).
2. Sealing Performance & Environmental Protection
Fully Closed Structure:
The tubular or U-shaped trough shell effectively blocks dust leakage, meeting the GMP dust-free standards in the food and pharmaceutical industries.
Reduces material loss (e.g., chemical powder) and environmental pollution risks.
Anti-Cross-Contamination:
Stainless steel materials (304/316L) have a smooth surface that is easy to clean, preventing bacterial growth.
3. Precise Flow Control
Frequency conversion motors adjust the rotation speed in real time to meet the conveying needs of different materials (e.g., precise feeding in the food industry).
4. Customizable Expansion
Supports special designs such as variable-diameter screws (anti-clogging), double screws (for cooling/drying processes), and side feeding.
Models & Configurations of Screw Conveyor

Selection Guide for Screw Conveyor Equipment
1. Material Characteristics
คุณสมบัติทางกายภาพ: Particle size, humidity, viscosity, and temperature.
Special Requirements: The food/pharmaceutical industry requires 316L stainless steel; acid-resistant alloy coatings are needed for corrosive environments.
2. Process Parameters
Conveying Capacity: Single-machine capacity (multiple machines in parallel are required for excessive capacity).
ความสูงในการยก: The maximum vertical height is 15m (enhanced bearing support is required for heights >10m).
Working System: Continuous operation or intermittent operation.
3. Power & Control System
กำลังมอเตอร์: For vertical conveying, it is estimated at 0.5-1.2kW per meter (a power ≥7.5kW is required for a height of 10m).
Speed Regulation Requirement: Frequency conversion control, suitable for scenarios requiring precise feeding (e.g., pharmaceutical production).
Safety Configuration: A torque limiter and brake (anti-reversal) are essential; the base needs to be reinforced in vibrating environments.
4. Material & Durability
304 Stainless Steel: Generally used in the food/chemical industry, with moderate corrosion resistance.
