SHJ Series Co-rotating Twin Screw Plastic Extruder can make following different kinds of plastic granules & particles: | Twin-screw Plastic Extruder has Different kind of Pelletizing method |
SHJ SERIES OF TWIN SCREW PLASTIC EXTRUDER | VARIOUS KINDS OF THE PARTICLES/GRANULES |
Features & Advantages i
(1) With the same direction parallel double shafts and twin-screw segments combined by a special design, the final plastic granules quality will be good and match the customers’ demands and requests. The screw segment combination could be adjusted by different plastic materials and different clients’ requirements.
(2) Both screw and barrel are combined. There are many kinds of screw elements, including conveying elements, kneading segments, shearing segments, reverse screw segments, and pressurized screw elements, which play different roles. According to the needs of material processing, various screw elements (screw segments) are combined by building blocks, and through optimization design, they can match and adapt to the processing of various process formulated plastic materials.
Features & Advantages ii
(3) The mixing, shearing, and kneading segments block have a geometric shape that has a spiral of the spiral block and the same direction of rotation, so that the spiral has a good material distribution and mixing ability, suitable for mixing operations. After the material enters the barrels after softening and melting, the twin screw in the meshing position in the opposite direction, a screw will pull the material into the meshing gap, and another screw will push the material out of the gap, so the material is transferred here by a screw to another screw, as "∞" movement. This movement has a large relative speed at the meshing position, which is very conducive to the mixing and homogenization of materials. Moreover, the gap in the meshing area is very small, and the speed of the thread and groove at the kneading point is opposite, which has a high shear effect, to achieve the uniform plasticization effect.
(4) The materials are melted in the barrels’ side by the barrels’ heaters heating, in the meantime, the materials will go ahead by the screw segments and shafts co-rotating (two shafts with screw segments rotating) the twin screw extruder is a dynamic reactor with reactive capacity. A series of chemical reactions, such as polymerization and grafting. Reactive extrusion processing is mainly used for the polymerization of monomers or oligomers: addition polymerization, polycondensation, free radical polymerization, and copolymerization; degradation of polyolefins and Controllable crosslinking; Graft modification of polymer: polar grouping of polymer or functionalization to achieve the purpose of material modification and preparation of compatibilizer; Forced blending modification of various materials. It also includes physical modification of materials, such as filling, mixing, toughening, and strengthening.
