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

Drive & Power Configuration

Dual independent motors with vertical/right-angle gearboxes direct-coupled drive:

Motor Power Output: 1.1 kW to 7.5 kW per motor
Motor Type: VFD-compatible AC motors (inverter duty)
Explosion-proof Options: Available for hazardous environments
Gearbox Reduction Ratio: Selected for target RPM (common ratios: i = 17, 24, 35)
