- The Model 970 can be designed for a 12" or 24" belt. Both belts are 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.
Theory of Operation
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 (MC³).
