Description

Technical Field

[0001] This utility model belongs to the technical field of ball mill equipment, specifically relating to a ball mill jar efficiency enhancement rack. Background Technology

[0002] A ball mill is a mechanical device used to further pulverize materials after they have been crushed. Specifically, when using a ball mill to grind hard materials, the material often adheres to the inner wall under centrifugal force, causing sliding wear on the mill jar. This results in significant wear on the inner wall of the mill jar, and the material after milling and sieving exhibits unevenness, or some materials are ground to a low fineness. During wet or dry milling, excessive moisture content in the powder, or static electricity, can also cause the powder to adhere to the grinding balls and the walls of the mill jar, leading to powder agglomeration and affecting the grinding effect. Simply extending the milling time may not achieve the desired results for these problems. Utility Model Content

[0003] In view of this, in order to solve the problems mentioned in the background art, the purpose of this utility model is to provide a ball mill jar enhancement rack.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A ball mill jar enhancement frame includes a main frame detachably connected to the ball mill jar lid. The main frame includes a positioning ring and a plurality of enhancement rods that can be closely attached to the inner wall of the ball mill jar, and the plurality of enhancement rods are fixed to the positioning ring in a circumferential array.

[0006] Preferably, the top of the main frame is fixed with a plurality of circumferentially arrayed positioning pins, and the positioning pins are detachably inserted into the ball mill jar cover.

[0007] Preferably, at least the exterior of the main frame is covered with a wear-resistant layer, and the wear-resistant layer is made of an elastic rubber material.

[0008] Preferably, the elastic rubber material includes, but is not limited to, nylon, polytetrafluoroethylene, and polyurethane.

[0009] Preferably, at least one of the main frames is a metal frame.

[0010] Preferably, the enhancing rod has an outer arc surface, and the enhancing rod is attached to the inner wall of the ball mill jar through the outer arc surface.

[0011] Preferably, the enhancing rod also has an inner guide surface, and the connection between the inner guide surface and the outer arc surface forms a side guide blade that can act on the inner wall of the ball mill jar.

[0012] Preferably, the inner guide surface includes an inner convex surface that convexes toward the center of the grinding jar.

[0013] Preferably, the inner convex surface is an inclined surface or an arc surface.

[0014] Preferably, the positioning ring includes an upper positioning ring and a lower positioning ring, and the enhancement rod is fixed between the upper positioning ring and the lower positioning ring.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] The efficiency-enhancing frame provided by this utility model enables the grinding balls in the ball mill to effectively uniformly distribute the fineness of the material during the grinding process, reducing the phenomenon of material clumping in dead zones due to excessive moisture or static electricity, thereby improving grinding efficiency.

[0017] In addition, wear on the booster frame and the inner wall of the grinding jar is reduced by coating the surface of the main frame with a wear-resistant layer.

[0023] 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.

[0024] Example 1

[0025] like Figures 1-4 As shown, a ball mill jar enhancement frame includes a main frame with a positioning pin 30 fixed at the top, and the main frame includes a plurality of enhancement rods 20 that can be closely attached to the inner wall of the ball mill jar.

[0026] The ball mill jar lid is provided with positioning holes corresponding to the positioning pin 30, and the enhancing rod 20 is parallel to the central axis of the ball mill jar. Therefore, during ball milling operation:

[0027] First, the overall enhancement frame is placed into the ball mill jar, thereby using multiple enhancement rods 20 to form multiple axially arranged inner protrusions inside the ball mill jar;

[0028] Then, the material is fed into the ball mill jar;

[0029] Next, put the ball mill jar lid on and make sure that the locating pin 30 is inserted into the locating hole on the ball mill jar lid;

[0030] Finally, the entire ball milling jar is started to rotate and grind the ball. During the grinding process, the enhancement rod 20 guides the material and grinding balls, thereby making the grinding balls move more frequently inside the ball milling jar and improving the grinding efficiency.

[0031] Furthermore, the main frame also includes a positioning ring 10, and a plurality of the enhancement rods 20 are fixed to the positioning ring 10 in a circumferential array.

[0032] Furthermore, at least the positioning ring 10 and the enhancement rod 20 are made of metallic material.

[0033] Furthermore, at least the positioning ring 10 and the enhancement rod 20 are covered with a wear-resistant layer 40. This wear-resistant layer is made of an elastic rubber material, including but not limited to nylon, polytetrafluoroethylene, and polyurethane. This reduces wear on the enhancement frame and the inner wall of the grinding jar, while also effectively reducing noise during grinding.

[0034] Example 2

[0035] like Figures 1-4 As shown, a ball mill jar enhancement frame includes an upper positioning ring 11, a lower positioning ring 12, an enhancement rod 20, and a positioning pin 30. The enhancement rod 20 is fixed between the upper positioning ring 11 and the lower positioning ring 12, and the positioning pin 30 is fixed to the top of the upper positioning ring 11.

[0036] The ball mill jar lid is provided with positioning holes corresponding to the positioning pin 30, and the enhancing rod 20 is parallel to the central axis of the ball mill jar. Therefore, during ball milling operation:

[0037] First, the overall enhancement frame is placed into the ball mill jar, thereby using multiple enhancement rods 20 to form multiple axially arranged inner protrusions inside the ball mill jar;

[0038] Then, the material is fed into the ball mill jar;

[0039] Next, put the ball mill jar lid on and make sure that the locating pin 30 is inserted into the locating hole on the ball mill jar lid;

[0040] Finally, the entire ball milling jar is started to rotate and grind the ball. During the grinding process, the enhancement rod 20 guides the material and grinding balls, thereby making the grinding balls move more frequently inside the ball milling jar and improving the grinding efficiency.

[0041] Furthermore, at least the upper positioning ring 11, the lower positioning ring 12, and the enhancement rod 20 are made of metallic material.

[0042] Furthermore, at least the upper positioning ring 11, the lower positioning ring 12, and the enhancement rod 20 are covered with a wear-resistant layer 40. This wear-resistant layer is made of an elastic rubber material, including but not limited to nylon, polytetrafluoroethylene, and polyurethane. This reduces wear on the enhancement frame and the inner wall of the grinding jar, while also effectively reducing noise during grinding.

[0043] Furthermore, regarding the enhancing rod 20 of Embodiments 1 and 2 above, such as Figure 3 As shown:

[0044] The enhancement rod 20 has an outer arc surface 21, and the enhancement rod 20 is in close contact with the inner wall of the grinding jar through the outer arc surface 21. This avoids the formation of a gap or dead angle between the enhancement rod 20 and the inner wall of the grinding jar.

[0045] The enhancing rod 20 also has an inner guide surface 22, and the connection between the inner guide surface 22 and the outer arc surface 21 forms a side guide blade 23 that can act on the inner wall of the grinding jar. The inner guide surface 22 includes an inner convex surface protruding towards the center of the grinding jar, and its inner convex surface is either a slope or an arc surface. Figure 3 In the process, the inner convex surface of the enhancing rod 20a is an inclined surface, and the inner convex surface of the enhancing rod 20b is an arc surface. Based on this, the material and the grinding balls can be guided along the inner guide surface 22 towards the center of the grinding jar when they come into contact with the enhancing rod 20, thereby achieving the purpose of ball milling.

[0046] In summary, the enhancement frame provided in the above embodiments effectively uniformizes the fineness of materials during the grinding process, reducing the phenomenon of material agglomeration in dead zones due to excessive moisture or static electricity, thereby improving grinding efficiency. Furthermore, the wear-resistant layer applied to the surface of the main frame reduces wear on the enhancement frame and the inner wall of the grinding jar. This wear-resistant layer, made of elastic rubber, also effectively reduces noise during ball milling.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
