Description

Technical Field

[0001] This utility model belongs to the field of ball mill technology, and in particular relates to a lubrication system for a ball mill. Background Technology

[0002] A ball mill works by placing materials and grinding balls inside a drum. The drum rotates, and the agitator blades inside stir, mix, and grind the materials and grinding balls. Understandably, ball mills are typically large and made of metal, with significant weight variations: small ones weigh about 3-5 tons, while large ones can reach 20-50 tons, and some even exceed 100 tons. This results in a large and heavy drum body. The drum body rests directly on four sets of rotating wheels. Although the rotation of the drum body is driven by a motor, the four sets of rotating wheels require sufficient lubricant to reduce friction. The traditional method of lubrication involves workers manually applying oil to the corresponding locations when the machine stops rotating. This increases labor and time costs. Furthermore, due to the layout of the equipment, many areas requiring lubrication have limited space, further complicating the lubrication process.

[0003] To this end, the applicant developed a lubrication system that can automatically inject oil into the ball mill. Utility Model Content

[0020] As attached Figures 1 to 6 As shown, this utility model provides a lubrication system for a ball mill, including a base 1 and a rotating assembly 2 and a roller assembly 3 mounted on the base 1. The rotating assembly 2 and the roller assembly 3 are connected by a cylinder drive to drive the cylinder to rotate.

With the above structure, the lubrication device 4 automatically injects oil into each component that needs to be lubricated, and oil can also be injected during the operation of the ball mill, which greatly reduces the workload of workers, reduces labor costs, and improves work efficiency.

[0021] Specifically, the lubrication device 4 includes an oil cylinder 41, an oil pump 42, a distribution valve 43, and several oil injection pipes 44.

The rotating wheel group 5 includes a first rotating frame 51, a second rotating frame 52, a connecting shaft 53, a bearing bracket 54, rollers 55, a first bearing 56, and a second bearing 57. The first rotating frame 51 and the second rotating frame 52 are set at a predetermined distance apart. The two ends of the connecting shaft 53 are respectively connected to the first rotating frame 51. The first bearing 56 and the second bearing 57 are connected to the second rotating frame 52. The first bearing 56 and the second bearing 57 are disposed on the connecting shaft 53 at a predetermined distance. The bearing bracket 54 is sleeved on the first bearing 56 and the second bearing 57. The roller 55 is sleeved on the bearing bracket 54. One end of the connecting shaft 53 extends inward with an oil injection hole 58. The oil injection hole 58 extends from between the first bearing 56 and the second bearing 57 and communicates with the bearing bracket 54. The oil injection hole 58 on the connecting shaft 53 is provided with a connector 59. The connector 59 is connected to the free end of the first oil injection pipe 441. At least one of the opposite sides of the first bearing 56 and the second bearing 57 does not need to be provided with a bearing end cap. The lubricating oil is directly injected into the inner ring of the bearing through the oil injection device.

[0022] See Figure 5 and Figure 6 Preferably, the lubrication device 4 further includes a first connecting member 45 and a first oil brush 46; the rotating assembly 2 includes a drive motor 21, a drive wheel 22, a driven wheel 23, and a chain 24.

[0024] Preferably, to improve the working environment, an oil collection trough 49 is provided below the chain 24; during the high-speed rotation of the chain 24, the oil collection trough 49 is used to collect the splashed lubricating oil and prevent a large amount of lubricating oil from splashing around the equipment; it can be understood that although the oil collection trough 49 cannot collect all the splashed lubricating oil, it still greatly improves the working environment of the equipment.
