[0002] Real stone paint is a kind of paint with decorative effects similar to marble and granite. It is mainly made of natural stone powder of various colors and is used for imitation stone effects on building exterior walls, so it is also called liquid stone. In the production process of real stone paint, the raw materials of real stone paint need to be initially crushed and then deeply ground, so a grinding device is needed.

[0003] However, we found a problem in actual application. The existing grinding device usually only grinds the real stone paint raw materials once, and the cooperation of the grinding sleeve and the grinding roller cannot fully guarantee the force to press the raw materials, resulting in insufficient grinding. This will cause some raw materials with larger particle sizes to directly enter the mixing unit, thereby affecting the overall quality of the slurry and the finished product. For this reason, a real stone paint raw material grinding device is proposed. Utility Model Content
