The POWDRIT weigh belt feeder is used for the continuous, gravimetric feeding of powdery bulk materials. Depending on the material to be handled, the infeed to the POWDRIT is controlled by a suitable prefeeder, i.e. rotary star feeder, feeding gate, etc.
The electronic controller works as an independent unit or integrated in a multi component system. It also controls the prefeeder, depending on the application, by an independent PID control loop as a function of the settling chamber filling level or in a classical double regulation loop, based on the beltload. The electronic controller can be linked to a supervisory process control system via an optional interface module.
