Screw Feeder: Loss-in-Weight and Gravimetric

Loss-in-weight and gravimetric feeders – ideal solutions

These devices meter dry solids through a rotating screw. They can be equipped with a scale system for true loss-in-weight weighing or simply rely on the consistency of the screw operating at a given RPM. We can meet your needs from heavy-duty abrasive handling to high-finish stainless steel USDA requirements including designs that can be easily disassembled for cleaning.

Loss-in-weight and gravimetric feeders are an ideal solution to your dry material metering needs. Designed for difficult-to-handle dry materials, the external agitation system eliminates product degradation, rat-holing, or bridging. The single-auger design provides uniform and accurate metering of the product.

The polyurethane Flex-Feed hopper is stronger, more resilient, and abrasion-resistant than vinyl. No cracks or ledges exist to collect material. The hopper interlocks with the cabinet for a tight seal. The patented auger- and feed-tube designs allow for quick, tool-less removal and re-assembly. In addition, we offer a weigh belt feeder, which are the most rugged feeders in the industry.

We offer several models of weigh belt feeders using NTEP-approved load cells. These weigh belt feeders are available in capacities ranging from 100 pounds per hour to 1000 tons per hour with custom designs for higher capacities. Calibration is quick and easy with the self-storing calibration weight design. The weights are specifically sized for the required application to provide the most accurate calibration possible.
