This series of production lines consists of two sets of extruders, with special and reasonable design, which is used to recycle high-moisture film and various foaming materials, which can ensure the mixing effect of sol and the compaction and plasticizing effect of the particles is more significant. The dual exhaust system increases the amount of exhaust, making the degassing more complete and the exhausting effect better. The whole plastic bag can be granulated without crushing, which greatly improves the production efficiency; the double piston screen changer can achieve non-stop changing the net, the filtering area is larger; the water ring pelletizer solves the material viscosity big problem; this system is specialized for pelletizing PE\PP film, woven bag, the final pellets are more dense, brighter color and good plasticizing effect
