Automatic scrap copper wire recycling machine cable granulator
1. After the PVC material is put into the high mixer for mixing, the powder material is put into the GLS-upper parallel twin screw extruder through the screw feeder.
2. The 0-upper-stage parallel twin-screw extruder mixes the materials uniformly, and completes the plasticization and mixing at a temperature of 140-160℃, and fully disperses them evenly. The post-extruded mixture material becomes a melt (temperature at 130-140℃) and directly falls into the large-diameter 0-lower-stage single-screw machine.
3. The 0-lower-stage single-screw extruder extrudes and pelletizes the melt at 120°C under low speed, high pressure and cooling. The temperature has dropped to 120-140°C during extrusion. Only then can the hot pelleting of the air-cooled die surface be completed, and the pellets will not stick during the pelletizing process.
4. The eagerly cut particles from the air-cooled mold surface are cooled by a secondary air-cooled cyclone separator, and the particle temperature is reduced to 35-40°C, and then through an air-cooled extended vibrating screen, the particle temperature is reduced to room temperature for delivery to the finished product Silo for packaging; PVC cable material granulator; high mixer-screw automatic feeder-twin screw granulator-single screw granulator ----- Opposing blowing eagerly cutting head-----first-level cyclone separator-------second-level cyclone separator-----extended air-cooled vibrating screen-----finished product bin.
