High Dispersion PET Plastic Recycling Machine , Low Shear Recycling Extruder Machine

PET-Recycling and Adhesives, multi-screw extruder, high dispersion and low shear, high output

Basic Design and Technological Features

12 Screw shafts arranged symmetrically in a ring rotate in the same direction each on its own axis. The

outer barrel and the stationary core enclose the screws with a narrow gap. Transportation of material takes

place in a double helix: around the statioinary core and around each screw.

The intermeshing section between the screws, often also referred as the "apex", is used extensively in the

RingExtruder as the central point of the process technology. In the intermeshing section, material is passed

to the adjacent screw with a change in flow direction and resulting in a 3D elongation flow without partial

overloading and leads to an excellent dispersion, wetting and homogenization.

In addition, the RE provides a high surface to volume ratio which is unmatched by any other multi screw

extruder. The combination of the more frequent passage of the intermeshing section and the high surface

to volume ratio is enhancing the degassing capability of the machine.

Finally the arrangement of the screw shafts in a ring largely coompensates the spreading forces known in

multi screw extruders and therefore reduces barrel and screw wear.
