Double-screw and single screw combination, decomposing the process, adding independent operating variables, conducive to optimizing the distribution of a technological process.
Combining same direction double screws with single screw’s advantage. Double-screw forced delivery、efficient mixing plastics and shear dispersion, inorganic head backpressure reflux, and single screw high-pressure extrusion, with low speed low shear, avoiding high shear overheating.
Apply to various types of heat-sensitive materials system and large capacity devolatilization, such as: PVC、XLPE、halogen-free flame retardant cable、shielding materials、high concentration of carbon black masterbatch and after rubber dehydration processing operations.
