SJZ series cone twin-screw extruders are special for various PVC powder materials. Mated with differentmoulds and auxiliary machinery, they can produce various PVC plastic pipes, profile materials, board materials,sheets, bars, and granulating materials.
The screw adopts oil cooling system while the barrel adopts air cooling system. The system is controlled bydedicated computers. According to customer requirements, most reasonable screws can be configured toachieve optimal plasticization and logistic quality. All the screws are processed by high-precision special NCscrew milling machines to ensure high consistency extruding performance. The most advanced variable pitchand depth screw design technology has been firstly introduced, making screw shearing and compressionmilder and itself more appropriate for practical requirement. The special design of distribution cabinet enlargesthrust bearing and adopts original bearings, guaranteeing the drive's long service life and the bearing of largerextrusion capacity. The electrical appliance system maximally adopts imported original parts and has manyfailure alarm functions, reducing failures and facilitating troubleshooting. The special design of cooling systemenlarges the heat radiation area and quickens the cooling with the temperature precision up to ±1℃.
