Process Control Corp., an Atlanta-based auxiliary equipment maker, announced two new gravimetric powder feeders designed for materials that do not flow freely.
The stainless-steel feeders can be used as stand-alone units or as part of a continuous system for blending power and pellets together. The units use a single-spiral, hollow-shaft auger to meter the material accurately.
The drive system uses a direct-current gear motor with an encoder, giving feedback on the motor so the feeder maintains a steady speed.
The weighing system is designed with Process Control's digital signal processing technology to filter out electronic noise and vibration. An agitator prevents material from bridging or clumping.
Both the weigh and drive modules are mounted in the same enclosure as the operator panel and are all pre-wired, which keeps field wiring to a minimum, the company said.
