Dispenser for plastic pellets (gravimetric feeder)
FlowSave Liad Weighing and Control Systems Ltd.

Continuous Loss-In-Weight Gravimetric Blender

FlowSave fulfills the extrusion sector's demands for accurate and homogenous dosing and constant blending. It provides extremely precise loss-in-weight blending and feeding of various size and bulk density materials such as pellets, regrind and powder.
FlowSave covers a wide production range of up to 1500 kg/h, and can feed up to 5 materials.
Separate load cells for each component allow constant monitoring for each component flow. If there are any changes in properties, e.g. bulk density, pellet size, etc. the FlowSave automatically adjusts individual feeders to match the extruder rate at the exact required ratio, without affecting the accuracy of the blended material. This ensures a constant blending ratio according to the recipe at all times.

Design
The FlowSave design, combined with brushless motors with integrated driving, guarantees a totally homogeneous blend.
The frame protects the dosing stations from the extruder's movements and vibration.
The system is completely modular. Feeders can be exchanged or removed as needed.

Precision
The material flow is monitored continuously, and the controller automatically regulates the rotation speed of the dosing screws. This ensures a precise homogenous blend of materials. Its high resolution weighing system allows precise low-rate additive feeding.

Savings
You can achieve maximum savings with the FlowSave. The final product shows a considerably lower fluctuation range, minimizing the usage of costly materials and reducing waste and start-up scrap. You can lower the additive percentage during operation, which also represents a significant saving.
