[0002] Colored paint is made by adding color powder to clear paint made from natural raw lacquer, or by adding various pigments and fillers to the paint to enhance the mechanical and chemical properties of the coating. Since both color powder and clear paint contain tiny particles, they should have high dispersibility, a certain base material content, appropriate construction viscosity and storage stability.

[0003] During the production process of paint, grinding equipment is usually required to grind larger powder particles into a specified fineness. This step is to obtain a color paste with uniform and fine pigment dispersion in the paint to ensure the quality of the paint;

[0004] The grinding equipment in the prior art is prone to uneven grinding of some special pigments during the grinding process. The fineness of the pigment itself is greater than the fineness required by the paint. For example, heavy calcium carbonate, mica iron oxide, graphite powder, etc. are difficult to meet the specific fineness requirements; at the same time, the existing grinding equipment is prone to uneven mixing of pigments after grinding. Therefore, a grinder for paint production is proposed to solve the above problems. Utility Model Content

The pigment after secondary grinding will gather at the bottom of the grinding tank 1. At this time, during the rotation of the transmission rod 21, it can drive the stirring rod 26 to further stir and mix the pigment, and finally discharge it through the discharge port 15 to complete the process.

[0027] Embodiment 2:

[0028] See also Figure 4-6 In order to achieve a good mixing effect for the pigment, the mixing assembly 3 in this embodiment includes a hopper 31, which is fixedly connected to the inside of the grinding tank 1, and a stirring barrel 32 is provided at the bottom of the hopper 31, and a gear ring 33 is fixedly connected to the stirring barrel 32.
