Description

Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to a device for repeatedly crushing raw materials of real stone coating. Background Art

[0002] Real stone paint is a coating with a decorative effect resembling marble and granite. It is primarily formulated with natural stone powder of various colors. It is applied to building exterior walls to create a simulated stone effect, hence the name "liquid stone." Natural stone powder, the primary raw material for real stone paint, is typically made from various natural stones that are initially crushed, screened, and then finely ground.

[0003] In the stone crushing process, a stone crusher is generally used, such as a building stone crushing device disclosed in patent CN221245358U. When working, the reduction motor drives two crushing rollers to rotate relative to each other through a belt and a pulley, thereby crushing the stones. The crushed stones are further screened by a screening plate to obtain the required specifications.

[0004] Although the above-mentioned crushing device can realize the crushing and screening of stones, the stones are only crushed once, and one crushing cannot guarantee that all stones can be fully crushed. The large stones screened out still need to be crushed multiple times to achieve the ideal effect. Therefore, the crushing effect is not perfect and still needs to be improved. Utility Model Content
