Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball mill partition plates, specifically a ball mill partition plate with high wear resistance. Background Technology
[0002] In industries such as mining, building materials, and metallurgy, ball mills are core equipment for material grinding. Their operating efficiency and the performance of vulnerable parts are directly related to the production capacity of the entire production line. As a key component inside the ball mill, the diaphragm plate mainly serves to separate the grinding chambers, control the material flow rate, prevent large particles from entering the chambers, and support the steel balls. During the high-speed operation of the ball mill, the diaphragm plate must withstand the high-frequency impact of the steel balls and the continuous scouring of materials (such as ore and cement raw materials) for a long time, making it one of the most severely worn components.
[0003] The current mainstream ball mill diaphragm plates generally suffer from insufficient wear resistance, which is reflected in the following aspects: the wear resistance is inherently weak. Most existing diaphragm plates are made of ordinary cast steel or low-chromium cast iron, and their surface hardness is much lower than that of steel balls and hard particles in the material. Under long-term impact and scouring, the surface of the diaphragm plate is prone to pitting and peeling. In particular, the wear rate of the through hole edges is faster, which leads to material flow into the diaphragm and a decrease in grinding efficiency.
[0004] To facilitate material flow, existing partition plates only have evenly arranged circular or rectangular through holes on their surface, without any wear-resistant mechanisms added for high-wear areas. However, these areas use the same thickness and material as other areas, making it impossible to specifically resist localized high wear. This further shortens the overall service life of the partition plates. Due to insufficient wear resistance, the partition plates need to be replaced periodically. After replacement, the equipment parameters need to be readjusted, increasing procurement costs and making the operation more cumbersome.
[0005] Therefore, developing a high-wear-resistant ball mill diaphragm plate that improves overall wear resistance by optimizing structural design and adding wear-resistant mechanisms, thereby extending service life and reducing replacement frequency, has become an urgent need to solve current industrial production pain points and improve the economic efficiency and stability of ball mill operation. Thus, it is necessary to design a ball mill diaphragm plate with high wear resistance to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a ball mill partition plate with high wear resistance to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a ball mill diaphragm plate with high wear resistance, comprising a body of a ball mill diaphragm plate, wherein a plurality of first through holes are uniformly arranged on the top of the body and near both sides, and a plurality of second through holes are uniformly arranged on the top of the body and between the two sets of first through holes, wherein a wear-resistant component is integrally formed on the surface of the body, and a protective layer is added to the inner side of the body.
[0008] Preferably, the wear-resistant component includes a wear-resistant ball integrally formed on one side of the body and located on the side of the first through hole, and a wear-resistant strip integrally formed on one side of the body and located on the side of the second through hole, wherein the wear-resistant ball is arranged alternately with the first through hole, and the wear-resistant strip is arranged alternately with the second through hole.
[0009] Preferably, the protective layer includes a substrate layer embedded inside the body, a wear-resistant layer embedded on the surface of the body, and a transition layer embedded between the substrate layer and the wear-resistant layer.
[0010] Preferably, the top of the wear-resistant strip has two fixing strips integrally formed.
[0011] Preferably, a baffle strip is fixedly connected to one side of the body and at both ends of the second through hole.
[0012] Preferably, one end of each of the two fixing strips is provided with a guide portion.
[0013] Preferably, the main body has three mounting holes on one side, and the three mounting holes are arranged in a triangle.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. Multiple first through holes are located on both sides, and the second through hole is an arc-shaped strip located between the two first through holes. The first and second through holes can screen and discharge materials to prevent large particles from entering the chamber, and also facilitate gas flow for heat dissipation (similar to a ventilated brake disc). The multiple sets of wear-resistant parts added to the surface of the main body can increase the strength and wear resistance of the main body to withstand the high-frequency impact of steel balls and the continuous scouring of materials (such as ore and cement raw materials) during the high-speed operation of the ball mill. The protective layer inside the main body can increase the wear resistance of the main body and greatly reduce the frequency of main body replacement.
[0016] 2. The wear-resistant strips are arc-shaped. The wear-resistant balls and wear-resistant strips can enhance the impact resistance of the body surface, while also increasing the thickness of the body and extending its service life after impact and friction. The wear-resistant balls and wear-resistant strips can also perform abrasive and material guiding operations on the material in operation, improving the wear resistance and service life of the compartment plate body.

[0021] 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.
[0022] Example 1
[0023] Please refer to Figure 1-3 As shown, this utility model provides a ball mill partition plate with high wear resistance, including a ball mill partition plate body 1. The top of the body 1 and near both sides are provided with a plurality of uniformly arranged first through holes 2. The top of the body 1 and between the two sets of first through holes 2 are provided with a plurality of uniformly arranged second through holes 3. The surface of the body 1 is integrally covered with wear-resistant parts. The inner side of the body 1 is provided with a protective layer. Three mounting holes 9 are provided on one side of the body 1. The three mounting holes 9 are arranged in a triangle.
[0024] It should be added that the three mounting holes 9 are arranged in a triangle to facilitate the installation of the body 1 and the equipment with bolts. Multiple first through holes 2 are located on both sides, and the second through hole 3 is an arc-shaped strip located between the two first through holes 2. The first through holes 2 and the second through holes 3 can screen and discharge materials to prevent large particles from entering the hopper, and also facilitate gas flow for heat dissipation (similar to a ventilated brake disc). The multiple sets of wear-resistant parts added to the surface of the body 1 can increase the strength and wear resistance of the body 1 to withstand the high-frequency impact of steel balls and the continuous scouring of materials (such as ore and cement raw materials) during the high-speed operation of the ball mill. The protective layer inside the body 1 can increase the wear resistance of the body 1 and greatly reduce the frequency of replacing the body 1.
[0025] Specifically, the wear-resistant component includes wear-resistant balls 4 integrally formed on one side of the body 1 and located on the side of the first through hole 2, and wear-resistant strips 5 integrally formed on one side of the body 1 and located on the side of the second through hole 3. The wear-resistant balls 4 and the first through hole 2 are arranged alternately, and the wear-resistant strips 5 and the second through hole 3 are arranged alternately. The top of the wear-resistant strips 5 is integrally formed with two fixing strips 6. The two ends of the body 1 and located on the side of the second through hole 3 are respectively fixedly connected with baffle strips 7. One end of the two fixing strips 6 is provided with a guide part 8.
[0026] Among them, the wear-resistant strip 5 is arc-shaped, and the wear-resistant ball 4 and wear-resistant strip 5 can enhance the impact resistance of the surface of the body 1, while also increasing the thickness of the body 1 and extending the service life of the body 1 under impact and friction. The wear-resistant ball 4 and wear-resistant strip 5 can also perform abrasive and guide operations on the material in operation, thereby improving the wear resistance and service life of the compartment plate body 1.
[0027] Furthermore, the two fixing bars 6 are arc-shaped, and the guide parts 8 at the ends of the two fixing bars 6 can divert the material. Then, the two fixing bars 6 can separate the material to prevent material accumulation, and the baffle bar 7 can separate the material.
[0028] More specifically, the protective layer includes a substrate layer 101 embedded inside the body 1, a wear-resistant layer 103 embedded on the surface of the body 1, and a transition layer 102 embedded between the substrate layer 101 and the wear-resistant layer 103.
[0029] In addition, the base layer 101 is mainly made of low-carbon low-alloy structural steel or cast steel, the transition layer 102 is made of medium-carbon low-alloy structural steel containing appropriate amounts of Cr, Ni, Mo and other materials, and the wear-resistant layer 103 is mainly made of high-chromium cast iron (Cr≥12%, containing Mo, V, Ni and other materials), with carbides distributed in a broken network or chrysanthemum pattern; or medium-carbon medium-chromium multi-alloy steel. The wear-resistant layer 103 provides high hardness and wear resistance, extending service life. The transition layer 102 alleviates stress concentration and prevents surface layer peeling. The base layer 101 ensures that the partition plate does not break under high impact conditions, effectively improving the wear resistance of the body 1 and extending its service life.
[0030] Working principle: When the material and abrasive balls impact the body 1, the wear-resistant balls 4 and wear-resistant strips 5 on the front side of the body 1 resist the material and reduce the impact force on the surface of the body 1. At the same time, the guide parts 8 at the ends of the two fixed strips 6 divert the material. Then the two fixed strips 6 separate the material. After the material is abraded and refined, the first through hole 2 and the second through hole 3 screen and discharge the material, which can also prevent large particles from entering the bin.
