High-speed disperser can produce a strong power of shear, impact and friction between the material and the dispersion disc through the high-speed rotation of the sawtooth dispersion disc, achieving the purpose of rapid dispersion, dissolution and uniform mixing. This equipment is featured by compact structure, stable performance, accurate frequency conversion, low energy consumption, stable hydraulic lifting performance, easy operation, easy disassembly of dispersion disc, and convenient cleaning. Therefore it is widely used for mixing and dispersing in coatings, inks, adhesives, emulsions, fine chemical materials, etc.
