Description

Technical Field

[0001] The utility model belongs to the technical field of grinding equipment, in particular to a high-efficiency ball milling device. Background Art

[0002] Grinding equipment is used to break up large particles and crush them to form powder. The most common type of grinding equipment is the ball mill. In the ball mill, multiple grinding steel balls of different sizes are placed in the cylinder. When the cylinder rotates, the steel balls inside rise to a certain height and then fall. When they fall, the material in the cylinder will be crushed. The material can be fully ground by repeated back and forth movements.

[0003] A Chinese patent application (or patent) with publication number CN220554711U discloses a ball mill for ceramic processing, belonging to the field of ceramic processing technology. It includes a base, a servo motor fixed to the top of the base, a stabilizing frame fixed to the top of the base, and located to the left of the servo motor. The output shaft of the servo motor is fixed to a rotating rod that penetrates the stabilizing frame and is rotatably connected to the stabilizing frame. A driving gear is fixed to the outer surface of the rotating rod. Shock-absorbing assemblies are fixed to the left and right sides of the top of the base. Support columns are fixed to the tops of the two shock-absorbing assemblies. A processing chamber that penetrates the support columns and is rotatably connected between the two support columns is rotatably connected between the two support columns. A driven gear that meshes with the driving gear is fixed to the outer surface of the processing chamber. In this ball mill for ceramic processing, the servo motor is started to drive the processing chamber to begin rotating, grinding and crushing the ceramic raw materials inside. When the processing chamber rotates, the impact force is reduced by the buffer columns in the shock-absorbing assembly, and then the impact force is dispersed to the left and right sides by the guide part, achieving the purpose of good shock absorption and reducing equipment wear.

[0004] The above-mentioned ball mill for ceramic processing has a feed pipe and a discharge pipe at both ends of its processing chamber, wherein the open end of the feed pipe faces upward, while the open end of the discharge pipe faces downward. However, both the feed pipe and the discharge pipe are arranged on the central axis of the processing chamber. Therefore, when discharging the material after grinding, the crushed material below the central axis is difficult to flow out of the processing chamber; and the processing chamber is provided with grinding balls, which will naturally fall as the processing chamber rotates, and collisions will occur between the grinding balls and between the grinding balls and the inner wall of the processing chamber. This collision will cause a large noise, and the collision between the grinding balls and the inner wall of the processing chamber will also cause certain damage to the processing chamber. To this end, we provide a high-efficiency ball milling device to solve the above-mentioned problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1-3The utility model is a high-efficiency ball milling device, including a base 1, on which is mounted a driving assembly 2 for providing rotational power to a driving ring 3. The cooperation of the driving assembly 2 and the driving ring 3 can cause the ball milling assembly 5 to rotate. At the same time, the supporting assembly 4 on the base 1 improves the stability of the ball milling assembly 5 during rotation.

[0032] Specifically, the shaft end of the driving motor 201 in the driving assembly 2 is connected to the rotating rod 202 through a coupling, and the rotating rod 202 is also sleeved with a driving gear 203. At the same time, the driving gear 203 is engaged with the driven gear 301 sleeved on the driving ring 3. A support assembly 4 is also provided on the front side of the head of the driving ring 3. The support frame 402 is welded to the upper side wall of the barrel frame 401 in the support assembly 4, and a half bearing 402a is embedded on the inner wall of the support frame 402.

[0033] Furthermore, a frame 101 is installed on the outer wall of the driving motor 2, and the driving motor 2 is connected to the base 1 through the frame 101. At the same time, the outer wall of the end of the rotating rod 202 is also inserted into the rod frame 102, and the rod frame 102 is connected to the base 1 through bolts. The support frame 402 contacts the outer wall of the outer cylinder 501 in the ball mill assembly 5 through the inner half bearing 402a thereof.

[0034] The operation process of this embodiment is as follows: when in use, the driving motor 201 works, and it drives the driving gear 203 to rotate through the rotating rod 202 on the shaft end, and then the driven gear 301 engaged with it drives the driving ring 3 to rotate, and because the driving ring 3 is sleeved on the outer wall of the outer cylinder 501, the outer cylinder 501 also rotates accordingly, which can drive the ball mill assembly 5 to rotate. While the outer cylinder 501 rotates, the bottom side of the head of the outer cylinder 501 is always in contact with the half bearing 402a, and then with the cooperation of the support frame 402 and the cylinder frame 401, the head of the outer cylinder 501 can be supported without affecting its rotation work.

[0035] Example 2

[0036] See also Figure 4-5 On the basis of Example 1, a ball mill assembly 5 is also provided. The sound insulation cotton 501d in the outer cylinder 501 and the vacuum chamber 501a in the ball mill assembly 5 can achieve a good noise reduction effect. The ground material can be screened through the inner cylinder 502 and the screen drum 503 inside it, thereby realizing classified discharge.

[0037] Specifically, a vacuum chamber 501a is provided between the inner side of the outer cylinder 501 and the outer side of the inner cylinder 502, a plurality of mounting grooves 501c for placing sound insulation cotton 501d are provided in a circular array in the side wall of the outer cylinder 501, and a discharge pipe 501b is also threadedly connected to the bottom side wall of the head of the outer cylinder 501, and a discharge chamber 502a is provided between the inner cylinder 502 and the screen drum 503 inside it, and an inner support block 502b for abutting the screen drum 503 is welded on the inner wall of the inner cylinder 502, and the outer wall of the inner cylinder 502 is welded. There is an outer support plate 502c for abutting the outer cylinder 501, and a discharge port 502d is provided at the bottom head of the inner cylinder 502, that is, the discharge pipe 501b passes through the outer cylinder 501 and the discharge port 502d in the inner cylinder 502 and is connected to the discharge cavity 502a. At the same time, a sieve hole 503a is provided on the outer wall of the sieve cylinder 503, and connecting sleeves 503b are sleeved on both ends of the sieve cylinder 503. The sieve cylinder 503 is connected to the two axial ends of the inner cylinder 502 through the connecting sleeves 503b, and a plurality of grinding balls 504 are also placed inside the sieve cylinder 503.

[0038] Furthermore, the outer cylinder body 501 has a cylinder cover 6 detachably fixedly mounted on both side axial ends, and a sealing plate 602 is provided on the inner wall of the cylinder cover 6, and the cylinder cover 6 is in contact with the outer wall of the axial end of the outer cylinder body 501 through the sealing plate 602. At the same time, a hopper 7 for material input is inserted in the center of the cylinder cover 6 on one side, and handles 601 are welded on the outer walls of the two cylinder covers 6.

[0039] The operation process of this embodiment is as follows: when the outer cylinder 501 is driven to rotate, the grinding balls 504 in the screen drum 503 are pulled to a certain height and then fall naturally. At the same time, the material to be ground is put into the hopper 7 by opening it, and the material enters the interior of the screen drum 503 along the hopper 7. Then, as the outer cylinder 501 continues to rotate, the grinding balls 504 continuously contact and collide with the material, and then the large pieces of material are broken into small pieces, and the small pieces are broken into powder. Finally, the material that meets the requirements passes through the hopper 7. The sieve holes 503a on the sieve drum 503 enter the discharge chamber 502a, while the non-compliant materials continue to remain in the sieve drum 503 and collide with the grinding balls 504. At the same time, the materials in the discharge chamber 502a can freely shuttle between the two sides of the sieve drum 503 to achieve a more refined grinding effect. When discharging is required, the valve on the discharge pipe 501b is opened, and because the discharge pipe 501b passes through the outer cylinder 501 and the inner cylinder 502 and extends into the discharge chamber 502a, the ground materials in the discharge chamber 502a can flow out.
