Description

Technical Field

[0001] This utility model relates to the field of tower mill technology, and specifically to a tower mill liner. Background Technology

[0002] With the continuous development of industrial technology, tower mills, as important grinding equipment, play a vital role in mineral processing and other fields. Traditional tower mill liners suffer from a relatively short service life because they are easily worn under the impact of high-speed rotation and slurry / steel balls. To improve liner lifespan, the commonly used tower mill liners on the market generally have a service life of 90-100 days. While this lifespan meets users' production needs to a certain extent, replacing the liners requires a 2-3 day downtime, which undoubtedly impacts production efficiency. Furthermore, frequent downtime for liner replacement increases users' maintenance and time costs.

[0003] Although the applicant improved the service life of the original liner by nearly 40% by embedding hard alloy rods during the casting process, users have gradually become more aware of cost reduction and efficiency improvement in recent years, so the applicant has made further improvements to the tower mill liner. Utility Model Content

[0004] The purpose of this utility model is to provide a tower mill liner.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tower mill liner includes a liner and reinforcing ribs. The reinforcing ribs are evenly arranged on the front and back of the liner, and hard alloy rods are provided on the reinforcing ribs. Magnetic blocks are fixed between the reinforcing ribs on the front of the liner. Zirconia ceramic sheets or zirconia ceramic mud are fixed between the reinforcing ribs on the back of the liner. Bolt holes are provided on the liner.

[0007] Preferably, the magnetic field strength of the magnetic block is 1200GS.

[0008] Preferably, the width of the reinforcing rib on the front is 35mm.

[0009] Preferably, the diameter of the cemented carbide rod is 16 mm.

[0010] Preferably, the width of the back side of the reinforcing rib is 10 mm. Beneficial effects

[0011] This application significantly improves the service life of tower mill liners to over 150 days, reducing the number of liners used and the frequency of replacement each year. It also adds the use of magnetic blocks and ceramic plates to the existing liner production technology, resulting in a substantial increase in service life, saving production costs and improving production efficiency.

[0012] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figure 1 As shown, a tower mill liner 1 includes a liner 1 and reinforcing ribs 2. The reinforcing ribs 2 are evenly arranged on the front and back of the liner 1, with a gap of 35mm between them. Hard alloy rods 3 are provided on the reinforcing ribs 2. 1200GS magnets 4 are fixed between the reinforcing ribs 2 on the front of the liner 1. Zirconia ceramic sheets 5 or zirconia ceramic mud are fixed between the reinforcing ribs 2 on the back of the liner 1. The ceramic sheets 5 have high wear resistance and self-lubricating properties. Bolt holes 7 are provided on the liner 1 for fixing the liner 1 to the tower mill.

[0022] Preferably, the magnetic field strength of the magnetic block 4 is 1200GS.

[0023] Preferably, the width of the reinforcing rib 2 on the front is 35mm.

[0024] Preferably, the diameter of the cemented carbide rod 3 is 16 mm.

[0025] Preferably, the width of the back side of the reinforcing rib 2 is 10mm.

[0026] In use: The tower mill contains steel balls with a diameter of 20mm. These steel balls impact and grind the material, achieving material crushing. During high-speed rotation, the steel balls and broken balls inside the tower mill come into direct contact with the steel balls adsorbed by the magnetic block 4, reducing friction on the liner 1 and ensuring full utilization of the steel balls, thus achieving the technical effect of ball milling. The steel balls inside the tower mill also come into direct contact with the ceramic discs 5, reducing resistance and ensuring normal operation of the tower mill. The liner 1 has liner protrusions 6 on its front side; both the reinforcing ribs 2 and the liner protrusions 6 are raised.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
