conical double screw extruder, single screw extruder
Plastic extrusion line machine
single screw plastic extruder:
single-screw extruder can apply to produce such products with thermoplasticity as pipes of PP, PE, PS, ABS, PMMA, PVC, as well as plates, sheets, rods, profiles and plastic pellets. According to different raw materials and product specifications, screws with different ratios of length diameter and compression, barrels of different structures and proper driving devices are adopted so as to make products with high quality.
· High output and low power consumption
· All hard teeth surface bears experienced heat treatment and fine grinding, the reduction box together with the inner forced cooling system ensure high efficiency, low voice and long lifespan
· The screw has been designed with reasonable geometric parameter. Corresponding to different raw materials and products, screws with different ratios of length diameter and structures are selected to meet different request of clients.
· In accordance with different requirements of raw materials, the heating section
of material barrel has two structures i.e. slot section and smooth section.
· Both screw and barrel are made of alloy steel with excellent properties, which
have advantages of abrasion resistant, anti-corrosion and high strength.
· The whole set is of reasonable and standard structure, which ensures
convenient operation and easy maintenance.

Conical double screw extruder:
SJSZ series of conical double-screw extruder is specializing in extruding pipes using various kinds of PVC powder. When equipped with different moulds and auxiliary machines, such products as any PVC pipes, profiles, plates, sheets, rods and pellets can be produced.
· The screw adopts circulating oil cooling device, so that the friction temperature would be quite allowable.
· The screw barrel adopts special designed wind cooling system, which makes repair quite easy.
· According to different material mixing requirements of clients, screws of reasonable structure can be equipped with to make sure desirable plasticization and quality of flowing substance.
· The centers of driving motor, reduction box and screw are assembled in a line, which ensures easy maintenance.
· The specially designed distributing box has extra-sized thrust bearings with long rotation lifespan. They are originally imported and can bear more powerful extruding pressure.
· Equipped with forced feeding device, the extruder ensures consistent speed of material discharging and extruding.
