Working Principle Comparison
Utilizes real-time load cells to precisely control material ratios by weight, featuring a closed-loop feedback system that automatically compensates for environmental variations. Achieves precision levels up to ±0.5% accuracy, making it ideal for sensitive production processes.
Volumetric Blender
Relies on volumetric measurement through screw speed or timing control. Susceptible to material density variations, humidity changes, and particle size inconsistencies, with typical accuracy ranging between ±2-5%.
Key Performance Comparison
| Criteria | Gravimetric Blender | Volumetric Blender |
|---|---|---|
| Blending Accuracy | ±0.5% | ±2%-5% |
| Material Waste Reduction | 30%-50% less waste | Higher waste generation |
| Energy Efficiency | 15%+ savings via dynamic power adjustment | Fixed power consumption |
| Climate Adaptability | Auto-compensation for humidity/temperature | Requires manual recalibration |
Market Suitability for South America
Low-Cost Materials (<$2/kg) with flexible tolerance (>3%)
