02 — Description

What the
equipment does

The conical screw compresses the material repeatedly and force-feeds it into the extruder feed zone.

The motor is controlled by a frequency inverter, so the feed rate can be adjusted and kept even. This keeps line operation and output stable.

The main advantage of the feeder: you skip the agglomeration step and save on the agglomerator, knife sharpening, feedstock drying, maintenance, operator wages, taxes and electricity.

03 — How it works

Feeding film
without agglomeration

An interactive drawing based on the photos, the specifications and open sources. A conical screw compresses light film and regrind and force-feeds them into the extruder's feed zone.

  • Conical screw: pitch and flight depth shrink towards the outlet, compressing the material
  • Film and regrind up to 50 mm; the extruder section shows how full its flights are
Loading the drawing…
Light film and fibres hardly enter an extruder screw on their own: they bridge in the hopper and the extruder runs starved. The conical screw of the feeder takes the material from the throat, compresses it again and again and forces it into the feed zone. The inverter sets the screw speed and with it the feed rate, up to 500 kg/h; in the drawing the feed is proportional to the frequency (a simplified model). The V-belt pulley is shown slowed down.
