Functional steps of material plasticating/mixing and silane-grafting are carried out in a long L/D co-rotating twin screw extruder, while single screw extruder is used for low temperature pressure buildup and pelletizing. This tandem line has a larger processing window than any single line.
It includes a term of technique and creativity, as well as a set of advanced facilities, whose ability is leading in China. By the investigation of market, air-cooling pelletizer, water-ring pelletizer, hot-face pelletizing underwater.
