The Model 970N Open Construction Weigh Belt Feeder has a 6” – 36” belt width that is designed to meter various materials into a process at a designed feedrate with gravimetric precision.
The feeder belt speed is varied to deliver material from a supply device into a process at a desired rate. A weight signal output and speed signal output are supplied for closed-loop process control.
