Product Description
High Precision Twin-Screw Metering Feeder
Custom sizes available for powders and granules. The technical specifications depend on target materials and processing requirements.
Control & Dosing Parameters
High-precision continuous dynamic weighing and dosing system with closed-loop electrical control:
- Dynamic Feeding Accuracy: ≤ ±1.0% (high-precision systems achieve ≤ ±0.5%)
- Static Weighing Accuracy: ≤ ±0.5%
- Turndown Ratio: 1:10 with VFD and PID closed-loop control
- Signal Output/Interface: 4-20mA analog, Modbus, Profibus, Profinet
Process & Conveying Capabilities
Throughput capacity determined by material density, screw diameter, pitch, and shaft speed:
- Rated Production Capacity: 0.5 to 200 t/h (typically 2-30 t/h for precision applications)
- Applicable Materials: Powders (cement, coal, carbon black), granules (grain, plastic pellets), and cohesive materials
- Conveying Incline Angle: Horizontal (0°) optimal, maximum 25°
Mechanical Configurations
Standard twin-screw feeder sizing guide:
| Model / Spec | Screw OD × Qty (mm) | Standard Pitch (mm) | Conveying Capacity (m³/h) | Rated Screw Speed (r/min) |
|---|---|---|---|---|
| Φ 150 × 2 | 150 × 2 | 160 | 5 ~ 10 | 25 ~ 80 |
| Φ 200 × 2 | 200 × 2 | 200 | 10 ~ 22 | 20 ~ 90 |
| Φ 250 × 2 | 250 × 2 | 250 | 20 ~ 36 | 20 ~ 90 |
| Φ 300 × 2 | 300 × 2 | 315 | 35 ~ 66 | 15 ~ 75 |
Inlet-to-Outlet Center Distance: Custom 1,500mm to 3,500mm
Flight-to-Wall Clearance: ≥10mm to prevent jamming
