Carbon black masterbatch/white masterbatch
Carbon black masterbatch granulation unit
■Granulation process: internal mixer-hoist-cone double feeder-single screw/double screw extruder-water ring pelletizing/water strand pelletizing
Basic formula ingredients: high molecular polymer (PE) carbon black zinc stearate, etc.
Basic process route: After mixing small materials such as resin, carbon black and mineral powder, they are put into the internal mixer, mixed and kneaded by the internal mixer to form a mass of material, which is forced to feed after being lifted. The glutinous rice is fed to a lambda single screw or double screw extruder through the feeder, and is further plasticized by the extruder, and then cut into granules by a water ring pelletizer.
Application field: Carbon black masterbatch, this process configuration can also be used for the production of white masterbatch after replacing it with a hot-cutting auxiliary machine
