[0002] The existing announcement number is CN 210753007 U. A water-based paint sand mill is provided. When working, a driving motor drives the main shaft to rotate, thereby driving the lower dispersion plate to rotate, stirring the material in the sand mill body. At the same time, the upward paddle located on the lower dispersion plate stirs the material while also driving the material to roll upward, and launches the grinding beads upward, and collides with the falling grinding beads, thereby further improving the grinding effect of the material.

[0003] The grinding of the above-mentioned water-based paint sand mill is achieved by the moving raw materials and grinding beads contacting and colliding with each other. However, by rotating the lower dispersion disk to eject the grinding beads and drive the raw materials to flow, there will be a greater rigid contact between the grinding beads and the dispersion disk, thereby reducing the grinding life of the dispersion disk and the grinding beads.
