SB SERIES SCREW FED GRANULATORS

Materials are evenly fed into the rotor via feeding screws. This feed method offers several advantages over gravity feeding: 

  • Higher throughput - as much as 50% more than gravity fed machines with the same size cutting chambers
  • Lower power consumption - the same throughput capacity as gravity fed granulators is often possible with 30% to 50% smaller motors
  • Can be used for dry or wet operation
  • Better quality - because the rotor is evenly balanced there are fewer fines in the regrind
  • Reduced noise
  • No fly-back

The large feed hopper allows a significant quantity of material to be loaded and automatically conveyed into the granulator.
Herbold holds the following Screw Feed Granulator patents:
US Patent Number: 7,793,872 B2
