Loss In Weight Feeder for Extrusion Machines

The loss in weight feeder is an accurate material conveying device that continuously measures and controls the material flow to achieve constant feeding. Widely used in plastics, chemical, food and other industries of raw material feeding. Its design is simple, easy operation and maintenance, is the key equipment to achieve automatic production and improve product quality.

Meanwhile, with the development and application of a PLC control system for centralized feeding and automatic weighing, Granuwel has achieved a closed-loop control through PLC that spans from raw material transportation, automatic weighing, twin-screw compounding, pelletizing, to automatic weighing and packaging.  This comprehensive system can provide clients with an all-in-one plant solution encompassing unpacking systems, storage systems, conveyance systems, metering systems, and visual management.

Features:

• Linear accuracy and repeatability precision can reach ±0.5%;
• The PLC control system replaces traditional single-chip microcomputers, fully compatible with upstream and downstream control systems, strong anti-interference, and fast signal transmission.
• Adaptable to hundreds of process routes, achieving a production capacity range of 0.5kg/h to 10000kg/h: meeting different formulation ratios and material characteristics;

Technical Features:

• Accurate Metering: The system utilizes weighing sensors to provide real-time feedback to the control module, adjusting the discharge volume and real-time tuning of the screw speed. This enhances discharge precision, achieving precise material rationing.
• Self-Diagnostic and Self-Recovery: Relevant instruments enable the system to perform self-diagnosis and self-recovery during operation, ensuring real-time detection and correction of deviations in the loss-in-weight feeder’s accuracy.
