SJSZ-80/156 conical twin screw extruder plastic extruder machine 450kg/h PVC pipe/profile/sheet extruder machine
Application
SJSZ series conical twin-screw extruder has advantages such as forced extruding, high quality, wide adaptability, long working life, low shearing speed, hard decomposition, good compounding &plasticization, and direct shaping of powder material and etc.
This extruder is equipped with AC motor, auto temperature controller, vacuum exhausting device etc. This production line is suitable for production of plastic pipe, plate and profile and etc.
Machine features
1. Model SJSZ series conical twin screw extruder is a kind of special equipment for extruding PVC compound. With different kinds of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe, profile, plate material, sheet material, bar material and granulation.
2. The conical twin screws have applied oil cooling system. Barrel is cooled by special wind cooling system.
3. The conical twin screw extruder system has applied special computer control. According to customers requirements, most reasonable structure of conical twin screw can be made so as to achieve best plasticity performance and material quality.
4. The conical twin screw is made by high precision special digital screw miller; extruding property can be highly harmonized. It has firstly introduced advanced technique of producing screw with variable pitch and depth, so that the material can be more softly sheared and cut.
5. The distribution box is specially designed, pull force bearing is fully imported, and the drive life span can be prolonged. It can bear larger extruding pressure.
6. The electrical system has mainly applied imported parts, it has multiple alarm system, and there are few problems which can be easily eliminated. The cooling system has applied special design, heat emission area is enlarged, the cooling is rapid, and temperature control tolerance can be ± 1degree.
