Description

Technical Field

[0001] The utility model relates to the technical field of colloid mills, in particular to a double-disc colloid mill. Background Art

[0002] The colloid mill is composed of stainless steel and semi-stainless steel colloid mills. The basic principle is to use high-speed relative linkage between fixed teeth and moving teeth. Except for the motor and some parts, all parts of the colloid mill that come into contact with the material are made of high-strength stainless steel. In particular, the key moving and static grinding discs are reinforced. Therefore, they have good corrosion resistance and wear resistance, making the processed materials pollution-free, hygienic and pure. In the chemical industry, colloid mills are often used for fine grinding and emulsification of coatings, paints, pigments, dyes, as well as the production, processing and experimental research of various products such as latex paint, lubricating oil, emulsified asphalt, etc.

[0003] The colloid mill is driven by an electric motor through a belt drive to drive the rotor and the matching stator to rotate relative to each other at high speed. One of them rotates at high speed and the other is stationary. The processed material is pressurized by its own weight to generate a downward spiral impact force. When passing through the gap between the stator and rotor teeth, it is subjected to strong shear force, friction force, high-frequency vibration, high-speed vortex and other physical effects, so that the material is effectively emulsified, dispersed, homogenized and crushed, achieving the effect of ultra-fine crushing and emulsification of the material.

[0004] When using an existing colloid mill for chemical-related operations, the direct fine grinding method causes the life of the grinding disc to decrease rapidly. For this reason, a double-grinding disc colloid mill is proposed. Utility Model Content
