GraviFeederTM
Introducing Rieco GraviFeederTM : Loss-in-weight Feeder
Accurate weighing with accuracy of +/-0.5% every time!
Welcome to the future of precision feeding with Rieco’s newly launched GraviFeederTM - LIW (Loss-in-weight) Feeders. Engineered for worldclass precision in feeding, our GraviFeederTM is the ideal dosing system for a diverse range of bulk solids in the food, pharmaceutical, chemical, or plastics industry, our advanced feeders deliver the accuracy and reliability you need.
Designed to excel in demanding environments, including high-temperature and ATEX zones, Rieco's GraviFeederTM - LIW Feeders ensure optimal performance by electronically balancing the weight of materials. This sophisticated technology allows the controller to precisely sense and adjust the weight of the material in the supply hopper, guaranteeing consistent and accurate dosing every time.
Our Loss-in-weight Feeders are available from capacity of 30 kg/h to 8000 kg/h to revolutionize your production processes, enhancing efficiency, accuracy, and safety in your operations.

Working Principle of Rieco GraviFeederTM LIW
Rieco Gravimetric LIW (Loss-in-weight) Feeders operate using a sophisticated and precise method to ensure accurate dosing of materials. The process involves the following key steps:
- Material Dosing:
A screw feeder doses powder from a hopper, periodically refilled from a larger storage silo.
- Weight Measurement:
The hopper, mounted on weigh cells, continuously measures the material's weight.
- Gravimetric Mode:
When not refilling, the system operates in gravimetric mode, calculating the flow rate by measuring the rate of weight loss and adjusting the screw feeder speed to match the desired discharge rate.
- Volumetric Mode:
During refilling, the system switches to volumetric mode, making educated guesses about the flow rate due to the net weight gain.
- Setpoint Regulation:
Operators set a predetermined feed rate, and the controller adjusts the feeder speed to maintain this rate, compensating for material flow variations and bulk density changes.
This process ensures accurate and reliable material dosing for various industrial applications.
