Continuous feeding. Continuous accuracy. Continuous trust.
Twin screw. Single screw. Vibratory. Belt. Choose your weapon.
Twin Screw Loss In Weight – Best for low-density, fluffy, aerated, non-free-flowing powders. Dual intermeshing screws for positive displacement & de-aeration.
Single Screw Loss In Weight – Best for free-flowing granules, pellets, standard powders. Cost-effective, reliable, easy to clean and maintain.
Vibration Type Loss In Weight – Best for fragile materials, flakes, shear-sensitive products. Gentle vibration conveying with precise amplitude control.
Belt Type Loss In Weight – Best for high-capacity, abrasive materials, bulk solids. Heavy-duty construction for mining, cement, large throughput.
Continuous Weighing – The 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 feed rate is compared to operator-set 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 (weight-based) control after refill.
Touchscreen HMI – Real-time display, trending, diagnostics, recipe management
Advanced PID Tuning – Self-adaptive or manual tuning options
Auto-Zero & Auto-Calibration – Maintains long-term accuracy
Remote Monitoring – SCADA, DCS, or MES integration
Alarm Management – Low hopper, refill fault, deviation alerts
Multi-Language Support – Operator interface customization
