Description

Technical Field

[0001] This utility model relates to the field of wear-resistant steel ball technology, specifically a wear-resistant steel ball with an uneven surface. Background Technology

[0002] In industrial processes such as grinding, crushing and mixing, wear-resistant steel balls inside a ball mill serve as an important grinding medium. Through the impact, compression and shearing action between the steel balls and the materials, the materials are crushed and mixed.

[0003] However, during use, traditional wear-resistant steel balls do not maximize the contact area between the steel balls and the material, which limits the improvement of grinding efficiency. At the same time, the severe surface wear of traditional wear-resistant steel balls limits their application effect and service life. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a wear-resistant steel ball with an uneven surface, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant steel ball with an uneven surface, comprising a steel ball body, with protrusions fixedly connected to both ends of the steel ball body in the diametrical direction, and a plurality of circular grooves equally spaced on the periphery of the protrusions, and a plurality of grooves equally spaced on the outer side of the steel ball body, the grooves being perpendicular to the protrusions, and a plurality of raised strips equally spaced on the outer end face of the steel ball body located between the circular grooves and the grooves.

[0006] According to the claim, a wear-resistant steel ball with an uneven surface is characterized in that the outer end face of the protrusion has an outward inclined surface, and the cross-section of the protrusion is arranged in a trapezoidal shape.

[0007] According to the claim, a wear-resistant steel ball with an uneven surface is characterized in that the inner edge of the circular groove has an inwardly inclined surface, and the cross-section of the circular groove is arranged in an inverted trapezoidal shape.

[0008] According to the claim, a wear-resistant steel ball with an uneven surface is characterized in that inclined surfaces are provided on both sides of the edge of the groove, and the position of the groove corresponds to the position of the circular groove.

[0009] According to the claim, a wear-resistant steel ball with an uneven surface is characterized in that the two sides of the convex strip are provided with cut surfaces, the inclination angle of the cut surfaces is set at 45°, and the position of the convex strip corresponds to the position of the circular groove.

[0010] According to the claim, a wear-resistant steel ball with an uneven surface is characterized in that the thickness of the protrusion and the protrusion strip is not more than 5 mm, and the depth of the circular groove and the recess is not more than 5 mm.

[0011] Compared to the aforementioned background technology, the present application provides a wear-resistant steel ball with an uneven surface; including a wear-resistant steel ball with very mature technology today, and core components with protrusions, grooves, circular grooves and convex strips. Its principle relies on the design of the outer surface of the steel ball to form an uneven shape, so that it can increase the contact area with the material, improve the grinding efficiency, and extend the service life.

[0012] This invention provides a wear-resistant steel ball with an uneven surface. Compared with the prior art, it has the following advantages:

[0013] This wear-resistant steel ball has an uneven surface. By setting convex heads, circular grooves, convex strips and grooves, the surface of the steel ball body can be made uneven. At the same time, the original rolling balance is not broken by designing convex heads, circular grooves, convex strips and grooves, while increasing the wear resistance of the steel ball body, increasing the contact area with the material, and improving the grinding efficiency of the material.

[0019] 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.

[0020] Please see Figure 1-4This utility model provides a technical solution: a wear-resistant steel ball with an uneven surface, comprising a steel ball body 1, with protrusions 2 fixedly connected to both ends of the steel ball body 1 in the diametrical direction. Multiple circular grooves 4 are formed on the periphery of the protrusions 2, with equal spacing. Multiple grooves 8 are formed on the outer side of the steel ball body 1, with equal spacing, and the grooves 8 are positioned perpendicular to the protrusions 2. Multiple raised strips 6 are fixed to the outer end face of the steel ball body 1 between the circular grooves 4 and the grooves 8, with equal spacing. The protrusions are provided on the outer side of the steel ball body 1. 2. The protrusions 2 are located at both ends of the diameter of the steel ball body 1 and are integrally formed with the steel ball body 1. The protrusions 2 can increase the contact area with the material, thereby improving the grinding efficiency. At the same time, circular grooves 4 are formed on the steel ball body 1 around the protrusions 2. There are multiple circular grooves 4, which can ensure the rotational balance of the steel ball body 1 and avoid affecting the balance and performance of the ball mill. Similarly, the circular grooves 4 can increase the contact area with the material, further improving the grinding efficiency. A groove 8 is formed on the outer end face of the steel ball body 1. The position of the groove 8 is perpendicular to the position of the protrusions 2. Figure 2 As can be seen, the groove 8 is arranged in a strip shape, which can increase different contact surfaces and provide material grinding. The protrusion 6 is fixed between the circular groove 4 and the groove 8. The protrusion 6 can increase the contact area with the material. The protrusion 6 is long and strip-shaped, and its contact area with the protrusion 2 is different, providing different grinding contact points and improving grinding efficiency.

[0021] like Figure 2 As shown, the outer end face of the protrusion 2 is provided with an outward inclined surface 3, and the cross-section of the protrusion 2 is arranged in a trapezoidal shape. The outward inclined surface 3 provided on the outer end of the protrusion 2 can reduce the wear of the protrusion 2 and avoid excessive grinding, while also ensuring that the steel ball body 1 can roll freely in the ball mill without being affected.

[0022] like Figure 2 As shown, the inner edge of the circular groove 4 is provided with an inwardly inclined surface 5. The cross-section of the circular groove 4 is set in an inverted trapezoidal shape. By opening the inwardly inclined surface 5, the internal utilization rate of the circular groove 4 is improved, so that the internal area of ​​the circular groove 4 can be maximized, thereby maximizing the grinding efficiency.

[0023] like Figure 3 As shown, inclined surfaces 9 are provided on both sides of the edge of the groove 8. The position of the groove 8 corresponds to the position of the circular groove 4. The inclined surfaces 9 are also to maximize the utilization of the contact surface of the groove 8, improve the grinding efficiency, and avoid excessive damage to the edge of the groove 8, thereby increasing the service life of the steel ball body 1.

[0024] like Figure 2As shown, the two sides of the raised strip 6 are provided with cut surfaces 7, and the inclination angle of the cut surfaces 7 is set at 45°. The position of the raised strip 6 corresponds to the position of the circular groove 4. The cut surfaces 7 on both sides of the raised strip 6 make the raised strip 6 more durable during grinding. The positions of the circular groove 4, the groove 8 and the raised strip 6 are all matched and the number and spacing are equal, which ensures the rolling stability of the steel ball body 1 and avoids the balance and performance of the ball mill being damaged during operation.

[0025] like Figure 2 As shown, the thickness of the protrusion 2 and the protrusion 6 is set to not exceed 5 mm, and the depth of the circular groove 4 and the recess 8 is set to not exceed 5 mm. The thickness of the protrusion 2 and the protrusion 6 is not more than 5 mm in order to further reduce the wear of the steel ball body 1 and improve the overall service life. Similarly, the depth of the circular groove 4 and the recess 8 is not more than 5 mm in order to reduce the wear of the steel ball body 1.
