This series of production line is composed of two sets of extruders. With special and reasonable design, it is used to recover the film with high moisture content and various foaming materials. It can ensure the mixing effect of sol and the density of rubber particles, and the plasticizing effect is more remarkable. The double exhaust system increases the exhaust volume, making the volatilization more complete and the exhaust effect better. The whole plastic bag can be granulated directly without crushing, which greatly improves the production efficiency; The double column type does not stop the machine to change the screen, so the filtering area is larger; Water ring granulation solves the problem of high viscosity of materials; The system is a special equipment for PE / PP film and woven bag, which produces dense particles, bright color and good plasticizing effect.
