Category: Single Screw Extruders
For general compounding of PE, PP, PS, ABS etc, non-vented type equipped as following
Screw and barrel in high-grade nitride steel, screw diameter 30 mm and L/D ratio of 30. Screw with Maddock mixing section at 22 D and with pineapple mixing at screw tip. Compression ratio 1 to 3. Screw speed infinitely variable from 0 to 200 RPM. Large oversized drive with 7.5 kW AC motor, coupled directly to an in line heavy-duty helical gear box, which in turn is connected to an individual housing containing the oversized thrust and position bearings for the screw drive.
The vented version of our 30 mm extruder has been developed with optimum performance and still no resin bleeding at the vent. The screw is designed for processing of most polymers and has the same features as described for the non-vented version as well as:
Vented screw design with Maddock mixing section at 15 D followed by the decompression and venting zone. The screw at the vent and to the end has double flights for optimum feeding property. The tip of the screw is equipped with split open flanges for additional mixing. Large vent opening made of Stainless Steel. Equipped with stainless steel swing open lid with large Polycarbonate window and with pipe connection for eventual vacuum pump. The swing open lid is equipped with rubber seal to give a tight vacuum fit to vent.
