Frequently Asked Questions About Loss-in-Weight Feeders

A loss-in-weight (LIW) feeder is a precision feeding system designed to deliver a consistent and accurate flow of bulk solids or liquids into a production process. Its primary purpose is to maintain precise material dosing by continuously monitoring the weight loss of the material source—typically a hopper or tank—over time. This ensures optimal process control, minimizes variability, and supports high product consistency, making it essential in applications where formulation accuracy and repeatability are critical.

These feeders are especially valuable in continuous processes where even minor deviations in feed rate can affect product quality, yield, or compliance with industry standards.

A loss-in-weight feeder operates on the principle of gravimetric feeding. The entire feeding system—including the hopper, feeder mechanism (such as a screw, belt, or vibratory tray), and drive system—is mounted on precision load cells that continuously measure the total weight of the material in the hopper.

As material is dispensed, the system detects the rate of weight loss in real time and compares it to the desired feed rate setpoint. If the actual rate deviates, the controller automatically adjusts the speed of the feeder (e.g., screw RPM or belt speed) to correct the flow. This closed-loop feedback mechanism ensures highly accurate and stable material delivery throughout the process.

Once the material level drops below a predetermined threshold, the system can pause feeding, refill the hopper, and resume operation—often with minimal interruption to the process.

Loss-in-weight feeders are widely used across industries that require high precision in material handling and formulation. Key sectors include:

• Pharmaceuticals: For accurate blending of active pharmaceutical ingredients (APIs) and excipients in tablet and capsule production.
