Understanding the Operation of Loss-in-Weight Gravimetric Feeders

A loss-in-weight gravimetric feeder operates on a closed-loop system to ensure precise material feeding rates as programmed into the machine's PLC. The feeder, hopper, and material are continuously weighed, and as the material is discharged, the system calculates the rate of weight decline using a load cell. This load cell helps adjust the feeder screw speed to maintain the desired discharge rate. The process includes a gravimetric phase, where material is discharged until it reaches a minimum level, known as the material heel, triggering a refill. The feed rate is graphically represented as the change in feeder weight over time. This cycle repeats continuously to support ongoing extrusion processes. #GravimetricFeeder #LossInWeight #MaterialHandling #IndustrialAutomation #ProcessControl #FeedRate #ExtrusionProcess
