[0002] In the cement production process, the gradation of cement particles has a significant impact on the performance of cement. Cement particles need to be ground to achieve the particle size required for production.

[0003] Existing graded powder equipment requires replacing grinding parts when grading different grades to meet different needs, and it is difficult to achieve fine grading of cement particles, resulting in unstable cement performance.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a graded grinding device based on optimized cement particle size distribution, in order to achieve a more practical purpose. Utility Model Content

By combining an inner and outer shaping cover with an inner and outer outer structure, the cement particles to be processed can enter the adjacent gaps. By utilizing the rotation of the inner shaping cover, the cement particles can be continuously ground to meet production requirements.

[0007] The side plate has an opening at the bottom and a screening discharge trough on the outer side of the side plate. A screening screen is installed on the inner wall of the side plate at an angle toward the end of the screening discharge trough.

[0008] An adjustment cover is provided on the upper part of the side plate, and a limiting cover extends from the top of the inner groove of the adjustment cover. The limiting cover is sleeved on the outer periphery of the lower part of the outer shaping cover.

[0009] The upper part of the outer shaping cover is sleeved on the outer periphery of the lower part of the feed cylinder. The upper part of the feed cylinder is provided with a drive assembly. The feed cylinder is connected to the adjusting cover through a support frame. The lower end of the drive assembly is connected to the inner shaping cover.

[0010] Several adjustment components are provided between the adjustment cover and the outer shaping cover, and the adjustment components can drive the outer shaping cover to move up and down reciprocally.

[0011] Preferably, the outer wall of the inner shaping cover is provided with grinding strips, which are distributed in a spiral pattern around the outer wall of the inner shaping cover.

[0012] Preferably, the adjustment assembly includes a cylinder and a connecting rod, one end of which is connected to the moving end of the cylinder, and the other end of which is connected to the outer shaping cover.

[0017] The beneficial technical effects of this utility model are:

[0018] 1. This utility model, through the combination of an inner and outer shaping cover with an inner and outer structure, allows the cement particles to be processed to enter the adjacent gaps.

[0020] The interlocking arc design of the inner and outer shaping covers not only increases the deformation resistance of the parts, thereby extending the service life of the grinding parts, but also ensures that the spacing between adjacent surfaces is the same, thus ensuring a longer grinding channel and further improving the grinding accuracy.

[0021] 2. This utility model has a lifting structure on the outside, which can move the outer shaping cover upward to facilitate internal cleaning. The bottom is provided with an inclined surface formed by a screening screen, which can screen the processed grinding particles and store them independently to better meet production needs.

[0022] 3. This utility model can be adapted to the processing requirements of cement particles by adjusting the distance between the outer shaping cover and the inner shaping cover;

[0023] 4. In this utility model, during rotary processing, the cement particles at the top will gradually move towards the adjacent space of the outer and inner shaping covers under the action of the grinding strips distributed in a spiral around the outer wall of the inner shaping cover.

[0041] like Figures 1-3 As shown, this utility model specifically relates to a grading and grinding device based on optimized cement particle size distribution, including an outer shaping cover 1 and an inner shaping cover 7. An adjusting cover 3 is sleeved on the outer bottom of the outer shaping cover 1, and a limiting cover 303 extends from the top of the inner groove of the adjusting cover 3. The outer shaping cover 1 is embedded in the inner side of the limiting cover 303, and a feeding cylinder 2 is connected to the top of the outer shaping cover 1. A transmission shaft 6 is provided at the central shaft end of the feeding cylinder 2, and an inner shaping cover 7 is installed at the bottom of the transmission shaft 6. Grinding strips 8 are welded around the outer wall of the inner shaping cover 7. A connecting rod 302 is horizontally installed around the outer wall of the outer shaping cover 1, and a cylinder 301 is vertically installed at the bottom of the connecting rod 302. A side plate 304 is connected to the bottom of the adjusting cover 3, and the bottom of the side plate 304 is open. A screening discharge trough 305 is provided on the outer side of the side plate 304, and a screening screen 4 is inclined towards the end of the screening discharge trough 305 on the inner wall of the side plate 304.

[0042] The inner wall of the limiting cover 303 is provided with an inner groove 306, and the inner groove 306 and the outer shaping cover 1 are sized to match each other.

[0043] A feeding trough 5 is provided on one side of the top of the feeding cylinder 2. A drive motor 9 is connected to the top extension end of the transmission shaft rod 6. The drive motor 9 drives the inner shaping cover 7 to rotate through the transmission shaft 6. The grinding strips 8 are distributed in a spiral around the outer wall of the inner shaping cover 7. The outer shaping cover 1 and the inner shaping cover 7 are arranged in a nested manner, and the cross-sections of the outer shaping cover 1 and the inner shaping cover 7 are both arranged in an S-shaped arc.

[0044] By combining the inner shaping cover 7 and the outer shaping cover 1 with an inner and outer structure, the cement particles to be processed can enter the adjacent gaps. By rotating the inner shaping cover 7, the cement particles can be continuously ground to meet production requirements.

[0045] The outer wall of the inner shaping cover 7 is provided with grinding strips 8, which can further enhance the grinding intensity and ensure the smoothness of the grinding process.

[0046] The interlocking arc design of the inner shaping cover 7 and the outer shaping cover 1 can increase the deformation resistance of the parts, thereby extending the service life of the grinding parts of the device, and also ensure that the spacing between adjacent surfaces is the same, thereby ensuring a longer grinding channel and further improving the grinding accuracy.

[0047] The outer side is equipped with a lifting structure, which can move the outer shaping cover upwards to facilitate internal cleaning. The bottom is equipped with an inclined surface formed by the screening screen 4, which can screen the processed grinding particles and store them independently to better meet production needs.

[0048] The spacing between the outer and inner shaping covers can be adjusted to adapt to the processing requirements of cement particles.

[0049] Working principle: For this type of grading and grinding device based on optimized cement particle size distribution, the top drive motor 9 rotates, which drives the bottom transmission shaft 6 and its inner shaping cover 7 to rotate. Then, the cement particles to be processed are fed into the feeding trough 5 on the feeding cylinder 2. After entering the feeding cylinder 2, the cement particles will diffuse outward under the action of centrifugal force, and gradually enter the gap between the outer shaping cover 1 and the inner shaping cover 7. They will then be gradually driven by the rotating grinding strips 8 and squeezed and separated by the outer wall of the inner shaping cover 7, thus achieving the appropriate grinding particles. The processed particles will fall onto the inclined screening screen 4 at the bottom, and be separated and collected after being screened by the screening screen 4.

[0050] The above embodiments are merely specific implementations of this utility model, used to illustrate the technical solutions of this utility model, and not to limit it. The protection scope of this utility model is not limited thereto.
