Gravimetric Feeder and Controller

Tecweigh is a leading designer and manufacturer of in-motion weighing and metering products for dry material handling applications in the food, chemical, plastics, minim and construction aggregates industries.

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.

Tecweigh feeders are flexible enough to accommodate a wide variety of dry materials, from fine powders to large pellets. Our three different sizes of feeders can move from 0.003 ft3/hr to more than 900 ft3/hr.
