Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cement grinding accessories, and more specifically, to a high wear-resistant grinding body for cement production. Background Technology
[0002] Cement grinding is the final and most energy-consuming step in cement manufacturing. Its main function is to grind cement clinker (as well as retarders, performance modifiers, etc.) to a suitable particle size (expressed by fineness, specific surface area, etc.), form a certain particle size distribution, increase its hydration surface area, accelerate the hydration rate, and meet the requirements for cement paste setting.
[0003] In existing technologies, cement grinding equipment typically uses grinding media such as steel balls, forged steel, or steel bars. However, due to the relatively simple surface structure of traditional grinding media, the grinding efficiency for cement is low, making it difficult to meet the requirements of precise particle size control in cement grinding processes, increasing energy consumption in cement production, and easily generating high-intensity friction during grinding operations, resulting in certain limitations in wear resistance and a short service life. Based on this, this utility model designs a highly wear-resistant grinding media for cement production to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a highly wear-resistant grinding media for cement production, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high wear-resistant grinding media for cement production includes a main grinding media and a plurality of protruding components spaced apart on the outer side of the main grinding media. The surface of the main grinding media is provided with a plurality of inner grooves corresponding to the protruding components. Each protruding component includes a hemispherical part and a plurality of protruding parts. The protruding parts are fixedly disposed at intervals on the surface of the hemispherical part. An assembly seat is fixedly installed inside the inner groove. A shaft pin is fixedly connected to the end face of the hemispherical part. The shaft pin is rotatably connected to the assembly seat.
[0007] As a preferred embodiment of this utility model, the surfaces of the main part, hemispherical part and convex part of the grinding body are all fixedly provided with a wear-resistant reinforcing coating, and the thickness of the wear-resistant reinforcing coating is 0.5mm-2mm.
[0008] As a preferred technical solution of this utility model, the wear-resistant reinforcing coating is a coating component made of tungsten carbide.
[0009] This design helps to improve the wear resistance of the grinding media.
[0010] As a preferred embodiment of this utility model, the outer opening of the inner groove is circular, and the diameter of the outer opening of the inner groove is the same as the diameter of the end face of the hemispherical part.
[0011] This setup ensures the overall appearance of the grinding media.
[0012] As a preferred embodiment of this utility model, the number of the protruding components is six, and the six protruding components are evenly spaced and distributed.
[0013] As a preferred embodiment of this utility model, the hemispherical part and the outward convex part are integrally formed.
[0014] This design ensures that the convex component formed by the hemispherical part and the convex part has good structural strength.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention features several protruding components spaced apart on the outer side of the main body of the grinding body. Each protruding component consists of a hemisphere and several protruding parts. The surfaces of the main body, hemisphere, and protruding parts of the grinding body are combined to form the surface of the grinding body, thereby optimizing the surface structure of the grinding body. This effectively increases the contact area between the grinding body and the material, improving the grinding efficiency for cement. It also facilitates meeting the requirements of precise particle size control in cement grinding processes and reduces energy consumption in cement production. The shaft pin is rotatably connected to the mounting base, allowing the protruding components on the outer side of the main body of the grinding body to rotate. This causes rolling friction when the hemisphere and protruding parts contact the material, reducing the friction intensity during grinding. The surfaces of the main body, hemisphere, and protruding parts of the grinding body are all coated with a wear-resistant reinforcing coating, which improves the wear resistance of the grinding body and extends its service life.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 4 As shown, this utility model provides a high wear-resistant grinding head for cement production, including a main grinding head 1 and a plurality of externally protruding components 3 spaced apart on the outside of the main grinding head 1. The surface of the main grinding head 1 and the externally protruding components 3 are provided with a plurality of internal grooves 2 corresponding to each other. The externally protruding components 3 include a hemispherical part 301 and a plurality of externally protruding parts 302. The plurality of externally protruding parts 302 are fixedly disposed at intervals on the surface of the hemispherical part 301. The surface of the grinding head is formed by the cooperation of the surfaces of the main grinding head 1, the hemispherical part 301 and the externally protruding parts 302, thereby optimizing the surface structure of the grinding head and effectively increasing the contact area between the grinding head and the material. An assembly seat 201 is fixedly installed inside the internal groove 2. A shaft pin 4 is fixedly connected to the end face of the hemispherical part 301. The shaft pin 4 is rotatably connected to the assembly seat 201. The externally protruding components 3 on the outside of the main grinding head 1 can rotate, so that the hemispherical part 301 and the externally protruding parts 302 generate rolling friction when they contact the material.
[0024] Among them, such as Figure 3 As shown, the surfaces of the main part 1, the hemispherical part 301 and the convex part 302 of the grinding body are all fixedly provided with a wear-resistant reinforcing coating 5. The thickness of the wear-resistant reinforcing coating 5 is 0.5mm-2mm. The wear-resistant reinforcing coating 5 is a coating component made of tungsten carbide, which is beneficial to improving the wear resistance of the grinding body.
[0025] Among them, such as Figure 1 and Figure 2 As shown, the outer opening of the inner groove 2 is circular, and the outer diameter of the inner groove 2 is the same as the end face diameter of the hemispherical part 301, thus achieving the purpose of ensuring the overall appearance of the grinding body.
[0026] Among them, such as Figure 1 As shown, there are six protruding components 3, which are evenly spaced and arranged.
[0027] Among them, such as Figure 1As shown, the hemispherical part 301 and the convex part 302 are integrally formed, which gives the convex component 3 formed by the hemispherical part 301 and the convex part 302 good structural strength.
[0028] The working principle of this utility model:
[0029] By providing several protruding components 3 at intervals on the outer side of the main part 1 of the grinding body, each protruding component 3 is composed of a hemispherical part 301 and several protruding parts 302. The surface of the grinding body is formed by the surface cooperation of the main part 1, the hemispherical part 301 and the protruding parts 302, thereby optimizing the surface structure of the grinding body and effectively increasing the contact area between the grinding body and the material, thus improving the grinding efficiency of cement. The shaft pin 4 is rotatably connected to the mounting base 201, and the protruding components 3 on the outer side of the main part 1 of the grinding body can rotate, so that the hemispherical part 301 and the protruding parts 302 generate rolling friction when they come into contact with the material, reducing the friction intensity generated during the grinding operation. The surfaces of the main part 1, the hemispherical part 301 and the protruding parts 302 of the grinding body are all provided with a wear-resistant reinforcing coating 5, which is beneficial to improving the wear resistance of the grinding body.
