1-5 mixing principle
The low-speed agitating slurry and the serrated dispersing disc installed on the high-speed dispersing shaft not only rotate but also revolve; at the same time, combined with the low-gap design of the agitating slurry, the low-speed agitating blade causes the material to generate strong kneading vibration movement and up-down/left-right circulation movement; The high-speed dispersing disc strongly shears and breaks up the material; thus ultimately ensuring that the material is fully dispersed and evenly dispersed (mixed).
