Description

Technical Field

[0001] This utility model relates to the field of gypsum powder production technology, specifically a grinding mill for gypsum powder production. Background Technology

[0002] Gypsum powder is a powder material with calcium sulfate as its main component. It is usually made from natural gypsum ore through processes such as calcination, dehydration, and grinding. Depending on the degree of dehydration, gypsum powder can be divided into various types and is widely used in construction, medical, artistic, and industrial fields. Gypsum powder is generally ground by a grinding mill.

[0003] The patent CN221638368U discloses a grinding mill for gypsum powder production. This patent discloses a technical solution for adjusting the size of grinding particles, which solves the problem that existing grinding mills cannot adjust the size of the ground particles as needed, resulting in certain limitations of the grinding mills. They cannot perform cyclic grinding of gypsum, resulting in insufficient grinding of gypsum powder, thus reducing the practicality of the grinding mill.

[0004] When in use, this device facilitates grinding gypsum to different degrees through the cooperation between the grinding blocks and the grinding wheel. However, the grinding blocks are located on the left and right sides of the grinding wheel, and there is a gap. This can easily cause gypsum powder to move to the bottom of the grinding wheel without being ground, resulting in low grinding efficiency and reduced grinding effect. Therefore, a grinding mill for gypsum powder production is proposed to solve the above problems. Utility Model Content

A storage battery 21 is fixedly installed inside the mounting groove 19.

[0028] The grinding chamber 1 is a hollow cylinder, and the drive rod 16 is rotatably connected to the grinding chamber 1 via a bearing.

[0029] Specifically, the electric push rod 18 is started, and the output end of the electric push rod 18 drives the grinding disc 9 to move upward, thereby adjusting the distance between the grinding disc 9 and the grinding ring 11. The drive motor 17 is started, and the output shaft of the drive motor 17 drives the drive rod 16 to rotate, thereby causing the grinding disc 9 to rotate. Through the cooperation between the grinding disc 9 and the grinding ring 11, the gypsum powder is ground.

[0030] It should be noted that the electric actuator 18 and the battery 21 are both conventional devices known to the public in the prior art, and their specific structures and working principles will not be described in detail in this article.

[0031] Please see Figures 1 to 3 In this embodiment, the grinding chamber 1 is provided with a filter assembly for filtering gypsum powder.
