Operation

The wet mix, which is typically prepared in a kneader, pug mixer or high shear granulator (pharma), is metered into the feed hopper by a feeder or hand fed. Twin screws transport material into the extrusion zone where tapered extrusion blades wipe material through perforated screens creating cylindrical extrudates of a controlled diameter. The extrudates break off by their own weight and are collected for the next processing step.

Features and Benefits

  • Radial extrudate discharge
  • Screw transport ensures plug flow operation, first in first out
  • Choice of twin extrusion screws to suit process
  • Variable shaft rotation speed
  • Easy scale-up
  • High yield
  • Better particle size distribution
  • Improved flowability 
  • Excellent process repeatability
  • Minimal holdup volume
