How It Works
- Continuous Weighing – Entire feeder system (hopper + material) is continuously weighed.
- Weight Loss Calculation – PLC calculates actual discharge rate by measuring weight loss over time.
- Real-Time Comparison – Actual rate compared to setpoint.
- Speed Adjustment – Controller adjusts feeder speed (screw, belt, or vibrator) to match setpoint.
- Automatic Refill – When hopper reaches low level, system triggers refill without interrupting process.
- Seamless Transition – Returns to gravimetric control after refill.
