The high-speed mixer (high-speed disperser) is the simplest one in the dispersing equipment. Its main function is to pre-disperse the pigment, and then mix it with the sand mill to carry out pigment dispersion.
The high-speed mixer is a high-speed rotation of the material through the national sawtooth special impeller (see Figure 1-1) to form a turbulent zone. In this area, the pigment particles are subjected to strong shear and impact, allowing them to be quickly dispersed into the paint slurry. However, at this time, no high pressure is generated, and the pigment particles cannot be well deagglomerated. Outside this area, a laminar flow is formed, and the upper and lower streams are divided so that the paint slurry is sufficiently circulated and turned and uniformly mixed.
The advantages of the high-speed mixer are: simple structure, easy operation, maintenance and maintenance; flexible use, mixing, dispersing and blending processes can be used; easy to clean and high production efficiency. It is one of the main production equipment used by the architectural paint factory (see Figure 1-2).
