[0036] In one embodiment of the present invention, the gypsum material grinding device of the above structure is used. The gypsum material to be ground is first placed in the feed hopper 32, and it will enter between the upper grinding disc 35 and the lower grinding disc 21 from the lower end of the feed hopper 32.

[0037] The driving motor 24 is controlled by the controller 7 to work. Under the action of the coupling 23, the rotating shaft 22 can be driven to rotate. The rotation of the rotating shaft 22 drives the lower grinding plate 21 to rotate. The rotation of the lower grinding plate 21 will cause relative rotation with the upper grinding plate 35. During the relative rotation of the lower grinding plate 21 and the upper grinding plate 35, the grinding operation of the gypsum material can be realized.

[0038] The gypsum material with a smaller particle size after grinding will eventually fall into the part of the base 1 between the annular support seat 28 and the dust cover 41 through the gap between the lower grinding plate 21 and the upper grinding plate 35. At the same time, the rotation of the lower grinding plate 21 drives the scraper plate 26 to rotate along with the lower grinding plate 21, thereby realizing the scraping operation on the part of the base 1 between the annular support seat 28 and the dust cover 41. When the gypsum material passes through the discharge port 42, it will enter the cylindrical bag channel 43. The lower end of the cylindrical bag channel 43 is tightened, so as to realize the dust-proof operation of discharging the gypsum material after grinding.

[0039] During the grinding operation of the gypsum material, the lifting cylinder 34 can be extended and retracted by the controller 7, so that the height of the lifting seat 33 can be adjusted. The height change of the lifting seat 33 drives the height change of the grinding shell 31, and the height change of the grinding shell 31 drives the height change of the upper grinding plate 35. The height change of the upper grinding plate 35 can realize the adjustment operation of the relative distance between the lower grinding plate 21 and the upper grinding plate 35, thereby realizing the control of the grinding particle size of the gypsum material.

[0040] It is worth noting that the controller 7 controls the operation of the drive motor 24 and the lifting cylinder 34 using existing technologies.

[0041] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
