Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a ball mill. Background Technology

[0002] Ball mills, as key equipment for material crushing, are widely used in industries such as cement, building materials, chemicals, and metallurgy. Their core function is to use the rotation of the cylinder to drive grinding media (such as steel balls or ceramic balls) to impact and grind materials, thereby achieving material refinement.

[0003] Concrete material has strong internal cohesion and high hardness. If it is directly fed into a ball mill, it will require a lot of energy and time to crush. In addition, existing ball mills directly screen the material through an inner cylinder with screen holes. The size of the screen holes is relatively limited, making it inconvenient to adjust the screen hole diameter according to actual use needs, and also inconvenient to maintain the screen holes.

[0022] In the attached diagram, all identical reference numerals refer to the same components.

[0023] like Figure 1-3 As shown, this utility model provides a ball mill, comprising:

[0024] The base 1 has two support seats 2 on its top. The support seats 2 have an outer cylinder 3 on their top. The outer cylinder 3 has a feeding assembly on one side. The inner cylinder 4 is rotatably installed inside the outer cylinder 3. The top and bottom of the inner cylinder 4 are fixed with screen plates 5 by bolts. The outer cylinder 3 has a protective cover 6 on its exterior.

[0025] The drive assembly includes a motor 7, a drive wheel 8, a drive wheel 9, a timing belt 10, a mounting rod 11, and a rotating rod 12.

[0026] Furthermore, the feeding assembly includes a feeding box 13, a feeding hopper 14, a second motor 15, a first gear 16, a second gear 17, a crushing roller 18, and a feeding pipe 19. The feeding pipe 19 has an L-shaped structure and is located on one side of the outer cylinder 3, with one end of the feeding pipe 19 connected to the inner cylinder 4.

[0027] Furthermore, a feed box 13 is provided at the top of the feed pipe 19, and a feed hopper 14 is provided at the top of the feed box 13. Gear 16 and gear 2 17 are rotatably mounted on the front side of the feed box 13, and gear 16 and gear 2 17 are meshed together. Motor 1 7 is mounted on the front side of the feed box 13 via a bracket. The rotating shaft of the motor is fixedly connected to gear 16. Two crushing rollers 18 are rotatably mounted inside the feed box 13, and one end of the two crushing rollers 18 is connected to gear 16 and gear 2 17 respectively.

[0028] Furthermore, a second motor 15 is installed on one side of the support base 2, and a rotating rod 12 is installed on the rotating shaft of the second motor 15. The other end of the rotating rod 12 passes through the support base 2 and is fixedly installed with a first drive wheel 8.

[0029] Furthermore, an installation rod 11 is rotatably installed on one side of the outer cylinder 3. One end of the installation rod 11 is fixedly connected to one side of the inner cylinder 4, and a second drive wheel 9 is fixedly installed on the other end of the installation rod 11. A synchronous belt 10 is sleeved between the first drive wheel 8 and the second drive wheel 9. The size of the first drive wheel 8 is larger than the size of the second drive wheel 9.

[0030] Furthermore, a controller is provided on the outside of one side support 2, a discharge pipe 20 is provided at the bottom of the outer cylinder 3, a valve is provided at the connection between the discharge pipe 20 and the outer cylinder 3, and multiple grinding balls are provided inside the inner cylinder 4.

[0031] Working principle: In use, the device is connected to an external power source and controlled by a controller.

[0032] Then, concrete raw materials are added into the feed box 13 through the feed hopper 14. The motor 15 drives gears 16 and 17 to rotate clockwise, which in turn drives the crushing roller 18 to rotate. The crushing roller 18 performs preliminary crushing of the concrete raw materials, which are then fed into the inner cylinder 4 through the feed pipe 19. Therefore, the time that the ball mill needs to spend grinding large pieces of material is greatly reduced, the overall grinding time is shortened accordingly, and the production efficiency is improved.

[0033] The rotating rod 12 and drive wheel 8 are driven by motor 7 to rotate. The synchronous belt 10 drives drive wheel 9 to rotate, which in turn drives mounting rod 11 and inner cylinder 4 to rotate. This causes the grinding balls and concrete raw materials inside the inner cylinder 4 to rotate, grinding the concrete raw materials. The concrete raw materials are then screened by sieve plate 5 and discharged through discharge pipe 20.
