Description of the loss-in-weight feeder
The RBP loss-in-weight feeder is an industrial device used for the weigh feeding of powdery or slightly granular materials. It consists of a feed hopper, a worm conveyor, a weighing system and a control system. It operates according to the principle of controlled loss in weight with the following main characteristics:
/ Stabilised accuracy: ±0.5%.
/ Flow rate range: from 12 l/h to 14 m3/h.
/ Completely enclosed feeder system.
/ Easy to maintain with little need for cleaning.
/ Manual or automatic feed.
Connectivity of the loss-in-weight feeder : The control module, also known as the SCMIII controller, ensures a stable flow rate at the output from the RBP loss-in-weight feeder by adjusting the rate to the defined setpoint. All the information and any alarms occurring during the feed process are then transmitted and recorded on the PDU console in real time.
