Melt-fed single screw extruders

Perfectly mix, optimally degas, and reliably cool with high throughput.

KraussMaffei Berstorff single-screw extruders feature a simple and robust machine construction, low need for maintenance, highest torques, and free structuring of the procedure part. Thanks to their variable expansion options, the single-screw extruders are used worldwide for a wide variety of process tasks.
Thus outstanding outputs and dimensions were achieved with the KE single-screw extruder. For example:

  • The world's largest screw diameter of 800 mm with throughputs of up to 74 t/h
  • Melt homogenization with Maillefer shearing parts in conjunction with intensive cooling
  • New standards for melt degassing in the manufacturing of bulk plastics
