All Thayer Scale feeders offer integrated material agitation zones, specialized auger designs and a wide range of proprietary feed algorithms to ensure reliable feeding of difficult materials. When paired with one of Thayer Scale’s rugged, counterbalanced platform or cable scales, the combination is a robust gravimetric feeding solution that integrates seamlessly into existing plant processes.
Thayer Scale’s loss-in-weight feeders incorporate a volumetric feeding subsystem designed to provide consistent, reliable metering of the target material at desired flow rates. (Flow rates may be as low as two grams/minute and as high as 100,000 pounds/hour.) To this volumetric feeder, we pair a fully mass-counterbalanced platform or cable scale designed to provide maximum signal and ensure accurate, reliable weight measurement in the most difficult operating conditions. We offer a powerful set of proprietary add-on accessories designed to solve problematic flow issues, such as bridging, flushing, adhesion, and cohesion. In addition, our instrumentation has powerful software routines specifically aimed at optimizing a feeder’s performance, such as output compensation, disturbance control, linearization, density compensation during refill, temperature compensation, and automated calibrations.
Thayer Scale’s loss-in weight feeders provide:
- Extended operating range
- Durable scales that withstand abuse
- A single load cell that can be accessed and/or replaced without removing the feeder/weigh hopper
- Flexible mounting options: floor-mounted, rotating, stationary, wheeled, forklift-based, suspended
- Fast access for cleaning
- Screw augers that can be changed without tools
- Damage-free handling of delicate and/or fragile materials
