Model SJSZ series twin conical screw extruder is a kind of special equipment for extruding PVC power. With different sorts of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe material, profiled material, board material, sheet material, bar material and granulation.
The screw has applied oil cooling system. Barrel is cooled by special wind cooling system. The system is all controlled by computer. According to customer's requirements, most reasonable screw can be made so as to achieve best plasticity state and material quality. The 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. The distribution box is special designed, and the thrust bearing is fully 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 the temperature control tolerance can be ±1℃.
