SJSZ series conical twin-screw extruder is suitable for extruding of PVC powder special equipment. With different molds and auxiliary machines can produce all kinds of PVC plastic pipes, profiles, plates, sheets, rods, and granulation. Screw with oil cooling system. Barrel using a special air cooling system. System uses a dedicated computer control. According to customer requirements, the preparation of most reasonable screw to achieve the best quality plastics and logistics status. Screw all the high-precision milling machine special machine screw, to ensure the performance of each extruding a high degree of consistency. Firstly introduced the most advanced variable pitch and depth of screw design technology, the logistics in screw shear, compression softer, closer to the actual needs. Distribution box is specially designed thrust bearing is particularly increased use of imported bearings, drive high life, www.zhongnuosuji.com plastic sheet production line, WPC profile production line, profile extrusion production line can be subjected to greater pressure. The electrical system adopts imported original, and has a number of fault alarm, fault less, excluding convenience. Special cooling system design, particularly to increase the cooling area, the rapid cooling, temperature control precision of ± 1 ℃.
