High Speed Dispersers: Advanced Technology for Optimal Results
High-speed disc disperser or high-speed mixer, is usually used in conjunction with grinding and dispersing machinery such as sand mills for mixing and pre-dispersion. For some pigment or coating dispersions with low dispersion fineness requirements, high-speed dispersers can also be directly used as grinding and dispersing machinery. In addition, it can also be used as paint mixing equipment . The main working component of a high speed disperser is the impeller, which rotates at a high speed and generates a large vortex due to the rolling circulation of the paint paste in the mixing tank. The pigment particles located on the upper surface of the paint paste will rapidly spiral down to the bottom of the vortex. A turbulent zone is formed around the edge of the impeller at a distance of 2.5-5 cm, in which the pigment particles are subjected to strong shear and impact effects, which is conducive to their rapid dispersion in the paint paste. Outside this zone, two flow streams, upper an...
