Description

Technical Field

[0001] The utility model relates to the technical field of coating processing, in particular to a coating grinding ball mill. Background Technique

[0002] The raw materials of coatings need to be ground. The grinding fineness plays a key role in the coating industry. It directly relates to the quality, performance and stability of coatings. Coating products with high grinding fineness have good film-forming quality, gloss and durability. At the same time, high grinding fineness can improve the storage stability of coatings and ensure the stability of products during long-term storage.

[0003] After retrieval, in the application with the patent application number 202320755413.5, a cement grinding ball mill is disclosed, including a bottom plate. The middle end of the top of the bottom plate is fixedly connected with a support plate through a support leg. The bottom of the support plate is fixedly connected with a rotating motor. The output end of the rotating motor is fixedly connected with a support plate. The output end of the support plate is fixedly connected with a ball mill box. The top of the ball mill box is fixedly connected with a grinding motor. The output end of the grinding motor penetrates into the inner cavity of the ball mill box, and the output end of the grinding motor is fixedly connected with a multi-stage grinding mechanism;

[0004] Although this cement grinding ball mill can drive the multi-stage grinding mechanism to rotate by setting a grinding motor, and through the combined use of a feeding box and a grinding disc, the material can be ground multiple times. However, when the grinding screen of this cement grinding ball mill rotates, due to gravity, the steel balls will be located below the material, and the material will press the steel balls on the grinding screen, restricting the movement of the steel balls, resulting in a poor grinding effect of the steel balls on the material.

[0005] Therefore, we propose a coating grinding ball mill. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a coating grinding ball mill, which solves the problem that when the grinding screen of the existing device rotates, the material presses the steel balls on the grinding screen, restricting the movement of the steel balls, resulting in a poor grinding effect of the steel balls on the material.

The outer surface of the rotating rod is fixedly installed with a first cross-shaped plate and a second cross-shaped plate. The first cross-shaped plate is located above the top surface of the grinding plate, and the second cross-shaped plate is located inside the grinding cavity.

[0010] Preferably, the distances between the first cross-shaped plate and the top surface of the grinding plate and between the second cross-shaped plate and the bottom surface of the grinding cavity are both smaller than the diameter of the steel ball. Uniformly distributed first bristles and second bristles are respectively fixedly installed on the bottom surfaces of the first cross-shaped plate and the second cross-shaped plate. Among them, by driving the rotating rod to rotate through the motor, the first cross-shaped plate and the second cross-shaped plate are driven to rotate, and the steel balls and raw materials can be stirred through the first cross-shaped plate and the second cross-shaped plate.
