[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 4 A device for controlling the specific surface area of ​​cement by open circuit grinding includes a ball mill body 1. The ball mill body 1 is a known technology, and its specific structure and working principle will not be elaborated in detail here.

[0025] The device also includes an installation groove 5 opened in the ball mill body 1, and a partition plate 6 is installed in the installation groove 5. The ball mill body 1 is provided with an auxiliary component at the installation groove 5. Specifically, the auxiliary component includes a slide plate 8 slidably connected to the installation groove 5, and a plurality of return springs 9 fixedly connected between the slide plate 8 and the installation groove 5. When the partition plate 6 is installed in the installation groove 5, the plurality of return springs 9 are compressed.

[0026] The ball mill body 1 is also provided with a guide groove 10 connected to the mounting groove 5. The slide plate 8 is arc-shaped, and the lower end of the slide plate 8 is fixedly connected to a guide rod 11 slidably connected to the guide groove 10. A plurality of return springs 9 are arranged on the outside of the guide rod 11, which can effectively prevent the return spring 9 from producing elastic deformation.

[0027] The side view of the mounting groove 5 is semicircular, and the side view of the sealing plate 3 is semicircular.

[0028] Two limit assemblies are symmetrically arranged on the ball mill body 1. Specifically, the limit assemblies include two sealing plates 3 symmetrically limited and slidably connected on the ball mill body 1. Sealing gaskets 32 are fixedly bonded to opposite ends of the two sealing plates 3 to ensure the sealing of the ball mill body 1.

[0029] Two sliding cavities 2 are symmetrically provided on the ball mill body 1 . The sliding cavities 2 are limitedly slidably connected with limit plates. The opposite ends of the two limit plates are fixedly connected with sealing plates 3 to prevent the sealing plates 3 from sliding off the sliding cavities 2 .

[0030] Grooves 31 are provided on the two sealing plates 3. The side view of the two grooves 31 is the same as the side view of the installation groove 5, and the two side views are respectively the upper and lower parts of the side view of the partition plate 6. When installing the partition plate 6, the two grooves 31 cooperate with the installation groove 5 to limit the partition plate 6, thereby realizing the positioning installation of the partition plate 6.

[0031] A limit spring 4 is fixedly connected between the sealing plate 3 and the ball mill body 1 . The limit spring 4 is always in a compressed state and not in an extreme compression state, thereby avoiding elastic fatigue of the limit spring 4 and increasing the service life of the limit spring 4 .

[0032] An operating block 7 is fixedly connected to the upper ends of the two sealing plates 3 on one side opposite to the other. By controlling the movement of the operating block 7, the sealing plates 3 are driven to move, thereby completing the installation and removal of the partition plates 6.

[0033] The specific working principle of the utility model is as follows:

[0034] When removing the partition plate 6, push the operating block 7 in opposite directions, driving the two sealing plates 3 to slide in opposite directions, and the limit spring 4 is further compressed. Under the elastic force of the reset spring 9, the slide plate 8 is driven to slide upward, driving the partition plate 6 to slide upward, so that the partition plate 6 can be taken out of the ball mill body 1 for inspection and replacement; when installing the partition plate 6, the above operation can be performed, and since the auxiliary components are provided, the installation of the partition plate 6 can be more stable.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
