- Production on an extruder with twin screws rotating in the same direction, with a screw diameter of 75 mm and a length/diameter (L/D) ratio of 40
- Capacity ranges from 600 to 1,000 kg/h, depending on material
Materials are filtered by a continuous screen changer with a fineness of 150 - 500 µm. Depending on the viscosity of the material, underwater pelletization yields granules between 2.4 and 4 mm.
The machine is specially designed for polyolefins. Four gravimetric weigh feeders are supplied with material via suction conveyor stations and bag chutes. These are located above a side feeder for (mineral) fillers and a weigher for pre-blends with several components. The materials are deaerated via two atmospheric extractors and a vacuum extractor.
