[0002] An internal mixer is a mechanical device used for mixing plastic or rubber materials. It is also called a closed plastic mixer. Its main working principle is to put the material into the internal mixing chamber and perform shearing, kneading, mixing and other operations through two relatively rotating rotors to achieve the purpose of mixing and plasticizing. A special automatic unloading mechanism needs to be installed on the feed port of the internal mixer.
