[0030] The working principle and use process of the present invention: The material is sucked into the homogenization chamber by the spiral feed shaft 334 through the feed flange 314, and then undergoes primary, secondary and tertiary graded shearing homogenization in sequence. During each stage of homogenization, the material is subjected to shearing force and impact force between the high-speed rotating rotor 331 and the stator 332, and the particle size gradually decreases. At the same time, the circulating cooling water in the water tank 4 enters the mechanical seal 325 to reduce the temperature of the mechanical seal caused by high-speed rotation. At the same time, the water tank 4 pumps cooling water into the mechanical seal 325 through the pipeline and the pump to cool the outer ring of the bearing through the circulating pump. By externally connecting the cooling circulating water, the jacket of the shell 313 is controlled by the circulating water to ensure that the material temperature is within the process requirements. The material is discharged from the discharge seat 312 after three-stage homogenization and shearing.
