Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to an asymmetric wear-resistant steel ball. Background Technology

[0002] In industrial fields such as ore grinding and material crushing, wear-resistant steel balls are key grinding media in ball mills, and their performance directly affects grinding efficiency and production costs. Although traditional wear-resistant steel ball designs have been optimized in structure and materials to improve wear resistance and service life, they still face some challenges in practical applications.

[0003] One major problem is that the movement trajectory of traditional wear-resistant steel balls in a ball mill is relatively fixed or predictable. This predictable movement pattern limits the contact area and interaction opportunities between the steel balls and the material, thus restricting the improvement of grinding efficiency to some extent. Especially when processing ores, due to their high hardness and irregular shape, traditional wear-resistant steel balls may struggle to fully crush larger stones, resulting in uneven grinding and affecting the quality of the final product and production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an asymmetric wear-resistant steel ball, solving the problem mentioned in the background art where the contact area between the steel ball and the material is relatively small under relatively regular motion conditions, resulting in low grinding efficiency. To achieve the above objective, this utility model is implemented through the following technical solution: an asymmetric wear-resistant steel ball comprising an outer ball, an eccentric chamber disposed inside the outer ball, the eccentric chamber being eccentrically positioned, an inner ball disposed inside the eccentric chamber, and six through holes disposed between the eccentric chamber and the outer wall of the outer ball, the six through holes being located above, below, in front, behind, to the left, and to the right of the inner ball, respectively; a crushing component disposed inside the outer ball, the crushing component comprising six sliding rods, the six sliding rods being slidably connected within the six through holes.

[0005] Preferably, the outer sphere is symmetrically divided into two hemispheres, which are connected by a connector, which includes a self-locking bolt and a nut.

[0006] Preferably, a striking block is connected to the end of the slide rod near the inner ball, and the inner ball contacts the striking block during movement.

[0007] Preferably, the end of the slide bar away from the impact block is connected to a cone, the cone being made of hard alloy material, and the cone protruding from the outer wall of the outer ball during movement.

[0008] Preferably, a spring is connected between the side of the impact block near the cone head and the through hole, and the spring surrounds the outer wall of the slide rod.

[0009] Preferably, a sealing ring is connected to the outer wall of the connection between the cone and the slide rod, and the outer wall of the sealing ring is in a hard-seal sliding connection with the inner wall of the through hole.

[0010] Preferably, the outer wall of the outer sphere is provided with a plurality of annular grooves, and the outer wall of the outer sphere is connected with a plurality of protrusions.

[0011] As can be seen from the above technical solutions, the asymmetric wear-resistant steel ball provided in the embodiments of this specification has at least the following beneficial effects:

[0012] This wear-resistant steel ball, through innovative designs such as an eccentric chamber and inner balls, achieves non-directional movement of the steel ball within the ball mill, significantly increasing the contact area and interaction opportunities between the steel ball and the material. This design not only improves grinding efficiency, enabling more effective crushing of ores in the early stages of grinding, but also optimizes the grinding effect, ensuring the quality and uniformity of the final product. Compared to traditional wear-resistant steel balls, this invention demonstrates significant advantages in improving grinding performance and reducing production costs. Attached Figure Description

[0020] 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.

[0021] Example 1

[0022] Please see Figures 1-5 As shown, an asymmetric wear-resistant steel ball includes an outer ball 1, inside which is an eccentric chamber 2. The eccentric chamber 2 is eccentrically positioned within the outer ball 1, resulting in uneven mass and a shifted center of gravity in the outer ball 1. Therefore, the entire outer ball 1 is essentially an asymmetric structure. When the outer ball 1 rolls in the ball mill, its trajectory is uneven due to its center of gravity deviating from the center. This irregular movement increases the contact area between the outer ball 1 and the material, thereby optimizing the impact and grinding effect. The cooperation between the outer ball 1 and the eccentric chamber 2 further enhances this effect, causing the outer ball 1's center of gravity to deviate from the center and resulting in an uneven trajectory. This irregular movement also increases the contact area between the outer ball 1 and the material, thus optimizing the impact and grinding effect.

[0023] Furthermore, an inner ball 3 is arranged inside the eccentric chamber 2, and six through holes 4 are arranged between the outer walls of the eccentric chamber 2 and the outer ball 1. The six through holes 4 are located above, below, in front, behind, to the left, and to the right of the inner ball 3, respectively. A crushing component 5 is arranged inside the outer ball 1. The crushing component 5 includes six sliding rods 52, which are slidably connected to the six through holes 4. A striking block 51 is connected to the end of the sliding rod 52 near the inner ball 3. The inner ball 3 contacts the striking block 51 during movement. A cone 53 is connected to the end of the sliding rod 52 away from the striking block 51. The cone 53 is made of hard alloy material and protrudes from the outer wall of the outer ball 1 during movement. When the outer ball 1 hits the material, the outer ball 1 pauses or decelerates, while the inner ball 3 continues to move in the direction of impact due to inertia, causing the inner ball 3 to hit the striking block 51 in that direction. After being hit, the striking block 51 drives the sliding rod 52 to move away from the inner ball 3. The sliding rod 52 drives the cone 53 along the through holes 4. The protruding surface of the outer ball 1 allows the cone 53 to achieve a crushing effect when impacting the material. In the initial stage of grinding ore materials, the impact of the cone 53 on some larger stones can promote the splitting process, thereby improving the grinding efficiency. A spring 54 is connected between the impact block 51 near the cone 53 and the through hole 4. The spring 54 surrounds the outer wall of the slide rod 52. When the impact block 51 is not in contact with the inner ball 3, the impact block 51, slide rod 52 and cone 53 are reset by the elastic force of the spring 54, causing the cone 53 to retract into the through hole 4. The elastic force of the spring 54 is small, and it can drive the impact block 51, slide rod 52 and cone 53 to reset without external interference, without affecting the impact force of the cone 53. Through the setting of the crushing component 5, when the outer ball 1 impacts the material, the cone 53 in the impact direction can protrude and impact the material to achieve the crushing effect, thereby accelerating the crushing efficiency of the material and improving the overall grinding efficiency.

[0024] Furthermore, a sealing ring 55 is connected to the outer wall of the connection between the cone 53 and the slide rod 52. The outer wall of the sealing ring 55 is in a hard-seal sliding connection with the inner wall of the through hole 4. The sealing ring 55 plays a sealing role, preventing a small amount of sand and gravel from entering the eccentric chamber 2 through the through hole 4, thereby aggravating the wear of the inner ball 3 and the crushing component 5. By setting the sealing ring 55, fine sand and gravel can be prevented from entering the eccentric chamber 2, thereby extending the service life of the inner ball 3 and the crushing component 5.

[0025] In addition, the outer ball 1 is symmetrically divided into two hemispheres, which are connected by a connector including a self-locking bolt and a nut. The outer ball 1 can be separated into two hemispheres by fasteners, which facilitates maintenance or replacement of parts and thus extends the service life of the outer ball 1.

[0026] In addition, the outer wall of the outer ball 1 is provided with multiple annular grooves 6. The multiple annular grooves 6 can guide some of the material to flow on the surface of the outer ball 1, increase the contact time and area between the material and the outer ball 1, and improve the grinding efficiency. The outer wall of the outer ball 1 is connected with multiple protrusions 7. The multiple protrusions 7 make the outer wall of the outer ball 1 form multiple protrusions, which increases the friction of the surface of the outer ball 1, thereby optimizing the grinding effect.

[0027] In use, the asymmetric wear-resistant steel ball of this invention, due to the eccentric arrangement of the eccentric chamber 2 within the outer ball 1, results in uneven mass and a shifted center of gravity in the outer ball 1. As the outer ball 1 rolls in the ball mill, its trajectory is uneven due to the deviation of its center of gravity from the center. While the outer ball 1 rolls, the inner ball 3 also moves continuously within the eccentric chamber 2. When the outer ball 1 impacts the material, it pauses or decelerates, while the inner ball 3 continues to move in the direction of impact due to inertia, colliding with the impact block 51 in that direction. The impact block 51 is subjected to... After the impact, the sliding rod 52 moves away from the inner ball 3, and the sliding rod 52 causes the cone 53 to protrude from the surface of the outer ball 1 along the through hole 4. Since the cone 53 is made of hard alloy material, it can break up materials upon impact. In the initial stage of grinding ore materials, the impact of the cone 53 on some larger stones promotes the splitting process, thereby improving grinding efficiency. The six cones 53 are distributed in the front, back, left, right, top, and bottom directions of the outer ball 1, enabling them to impact materials from various angles. The material is crushed. When the impact block 51 is not in contact with the inner ball 3, the impact block 51, the sliding rod 52, and the cone 53 are reset by the elastic force of the spring 54, causing the cone 53 to retract into the through hole 4 and not protrude from the outer wall of the outer ball 1. The elastic force of the spring 54 is relatively small, and it can drive the impact block 51, the sliding rod 52, and the cone 53 to reset without external interference, without affecting the impact force of the cone 53. The sealing ring 55 moves with the cone 53 and the sliding rod 52, and the sealing ring 55 plays a sealing role, preventing a small amount of sand and gravel from entering the eccentric chamber 2 through the through hole 4, thereby increasing the crushing efficiency. Wear of the inner ball 3 and the crushing component 5; the setting of the crushing component 5 allows the cone 53 of the outer ball 1 to protrude and impact the material when it impacts the material, thereby achieving the crushing effect, thus accelerating the crushing efficiency of the material and improving the overall grinding efficiency. The setting of the sealing ring 55 can prevent fine sand and gravel from entering the eccentric chamber 2, thereby extending the service life of the inner ball 3 and the crushing component 5; the outer ball 1 can be split into two hemispheres by fasteners, which is convenient for maintenance or replacement of parts, thereby extending the service life of the outer ball 1.

[0028] Multiple annular grooves 6 can guide some material to flow on the surface of the outer ball 1, increasing the contact time and area between the material and the outer ball 1, and improving grinding efficiency. Multiple protrusions 7 form multiple raised parts on the outer wall of the outer ball 1, increasing the friction on the surface of the outer ball 1, thereby optimizing the grinding effect. Through the cooperation of multiple annular grooves 6 and multiple protrusions 7, some material can slide along the annular grooves 6, increasing the contact time and area between the material and the surface of the outer ball 1. Multiple protrusions 7 can increase the friction of the outer ball 1, further optimizing the grinding effect.

[0029] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
