Many feeders from other manufacturers are based on a reactive control (follow-up), but PFISTER feeders utilise pro-active control In the pro-active rotor weighfeeder, the material mass is measured before it leaves the rotor weighfeeder That means that the speed of the rotor is adjusted before the material is discharged into the system.
