The planetary mixer has a unique and novel mixing form. There are two or three multi-layer blade agitators and 1 to 2 automatic scrapers in the kettle. While the agitator revolves around the axis of the kettle body, it also rotates around itself at different speeds. The axis rotates at a high speed, which makes the material make complex movement in the kettle body, and its efficiency is usually several times that of ordinary mixers when subjected to strong shearing and kneading.Common planetary mixers usually consist of two low-speed planetary agitating paddles (usually multi-inclined paddle type, twist type, frame type), one or two high-speed planetary agitating paddles (dispersing discs) and wall scraping paddles.
