Description

Technical Field

[0001] This utility model relates to the field of cement mill technology, specifically to a cylindrical mixing liner structure. Background Technology

[0002] Cement clinker production is a key step in the cement manufacturing process, mainly including raw meal preparation, clinker firing, and cooling.

[0003] Cement mills are key equipment for further pulverizing materials after they have been crushed. They are widely used in the cement production industry. In cement mills, liners are key components inside the mill. The main function of liners is to protect the mill cylinder from direct impact and wear from the grinding media and materials. Through their special design, they can improve grinding efficiency. At the same time, liners can also be used to adjust the movement of the grinding media to enhance the pulverizing effect of the grinding media on the materials, increase output, and reduce metal consumption.

[0004] In cement mills, the material tends to agglomerate in the second chamber during actual grinding, resulting in low powdering efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a cylindrical stirring liner structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cylindrical mixing liner structure includes a cement mill and a liner installed inside the cement mill. The liner includes a plate body with a through hole in the middle of the plate body. A crushing structure is integrally connected to the plate body. Ribs for mixing are provided on the plate body on both sides of the mounting hole. The ribs are arranged at an angle.

[0008] As a preferred embodiment of this utility model, the liner plates are arranged in a spiral structure along the axis of the cylinder on the inner wall of the cement mill.

[0009] As a preferred embodiment of this utility model, the liner is arranged in an arc shape.

[0010] As a preferred embodiment of this utility model, the stiffening plate is made of high-strength steel.

[0011] As a preferred embodiment of this utility model, the surface of the crushing structure is provided with a wear-resistant coating.

[0012] As a preferred embodiment of this utility model, the liner plate is made of high-strength wear-resistant alloy steel, and the thickness of the plate plate ranges from 10mm to 30mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] To address the problems mentioned in the background art, this application adds ribs with a stirring effect at an angle above the liner, and further improves the grinding effect by arranging the liner in a spiral structure in the circumferential direction, thereby maximizing the effect.

[0015] Vertical and diagonal stiffeners are added to the surface of the plate to act as a mixer. When the liner is installed, it is arranged alternately along the axis of the cement mill cylinder to form a spiral structure in the circumferential direction, which solves the problem of material agglomeration. This method changes the traditional uniform distribution method and adopts an alternating spiral structure, which effectively solves the problem of material agglomeration and significantly improves grinding efficiency.

[0016] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0024] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0025] Please see Figure 1-6This utility model provides a technical solution: a cylindrical mixing liner structure, including a cement mill 1 and a liner 2 installed inside the cement mill 1. The liner 2 includes a plate body 21, with an installation hole 22 through the middle of the plate body 21. A crushing structure 211 is integrally connected to the plate body 21. Ribs 23 for mixing are provided on the plate body 21 on both sides of the installation hole 22. The ribs 23 are arranged obliquely. The liner 2 is arranged in a spiral structure along the axis of the cylinder on the inner wall of the cement mill 1. The liner 2 is arranged in an arc shape. The ribs 23 are made of high-strength steel. The surface of the crushing structure 211 is coated with a wear-resistant coating. The plate body 21 of the liner 2 is made of high-strength wear-resistant alloy steel, and the thickness of the plate body 21 ranges from 10mm to 30mm.

[0026] It should be noted that, in this embodiment, the plate 21 has a through hole 22 in the middle for fixing the liner 2 to the inner wall of the cement mill 1. The crushing structure 211 is integrally connected to the plate 21 to enhance the crushing effect of the material. The ribs 23 are set on the plate 21 on both sides of the mounting hole 22 in an oblique structure to stir the material and prevent agglomeration.

[0027] Furthermore, the liners 2 are arranged alternately along the axis of the cylinder on the inner wall of the cement mill 1 to form a spiral structure. This arrangement can effectively improve the flow state of the material, reduce agglomeration, and improve grinding efficiency.

[0028] The liner 2 is designed with an arc shape to better fit the inner wall of the cement mill 1 cylinder, ensuring a tight fit between the liner 1 and the cement mill 1 cylinder and reducing wear.

[0029] The stiffener 23 is made of high-strength steel to ensure its wear resistance and structural strength. The surface of the crushing structure 211 is provided with a wear-resistant coating to further improve its service life. The plate body 21 is made of high-strength wear-resistant alloy steel with a thickness ranging from 10mm to 30mm to ensure the overall strength and wear resistance of the liner.

[0030] By using the obliquely arranged ribs 23 and the spiral structure, the material agglomeration problem is effectively solved, and the grinding efficiency is significantly improved. The design of the crushing structure 211 further enhances the crushing effect of the material and improves the grinding efficiency. The use of high-strength wear-resistant alloy steel and wear-resistant coating significantly improves the service life of the liner and reduces maintenance costs. Feedback from field trial operation results proves that the structure is simple, effective, and has high practicality and economy.

[0031] High-strength steel (stiffening plate 23) provides sufficient structural strength and wear resistance, ensuring long-term use of stiffening plate 23 under high load conditions. Wear-resistant coating (crushing structure 211) further improves the wear resistance of the crushing structure and reduces damage caused by material impact and wear. High-strength wear-resistant alloy steel (plate 21) ensures the overall strength and wear resistance of liner 2. The thickness ranges from 10mm to 30mm, and the appropriate thickness can be selected according to the actual working conditions to meet different wear resistance requirements.

[0032] This invention effectively solves the problem of material agglomeration in the second chamber of a cement mill by optimizing the design and material selection of the liner, significantly improving grinding efficiency and the service life of the liner 2, and has high application value and promotion prospects.

[0033] The working process of this utility model:

[0034] In use, the liner 2 is fixed to the inner wall of the cement mill 1 through the mounting holes 22. The liner 2 is arranged alternately along the axis of the cement mill 1 cylinder, forming a spiral structure to ensure smoother material flow within the mill. After entering the cement mill, the material undergoes preliminary crushing. At this point, the crushing structure 211 further crushes the material, enhancing the grinding effect. The obliquely arranged ribs 23 agitate the material during mill rotation, preventing material agglomeration. The spiral arrangement of the liner 2 ensures more uniform material flow within the mill, reducing local accumulation and agglomeration. During the grinding process, the arc-shaped structure of the liner 2 fits tightly against the mill cylinder of the cement mill 1, reducing wear and improving grinding efficiency. The high-strength wear-resistant alloy steel material and wear-resistant coating further extend the service life of the liner and reduce maintenance costs. After thorough grinding, the material reaches the required fineness and is discharged from the cement mill to enter the subsequent cement production process.

[0035] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
