Description

Technical Field

[0001] The invention relates to the technical field related to tungsten carbide powder processing, in particular to a ball mill for tungsten carbide powder with vibrating screen crushing. Background Art

[0002] As an important grinding equipment, the ball mill uses the internal grinding media such as steel balls or ceramic balls to produce strong impact and grinding during the rotation process, further refining the tungsten carbide powder to the required particle size range;

[0003] However, when the existing ball mill is used, the material can be crushed by the setting of the crushing mechanism. However, during the crushing work, it is very easy to cause the size of the crushed material to be different, and the efficiency of the ball milling process is low at this time;

[0004] In order to overcome the above-mentioned defects, reference can be made to the ore secondary crushing device disclosed in the prior art (application number CN202410772209.3, published on August 27, 2024 in China). The crushing roller of the crushing device rotates relative to the teeth on the outer cylinder, so it has a higher relative speed than the single cylinder rotating structure and has high crushing efficiency. The present invention reduces the load of the ball mill, thereby reducing the loss of the ball mill and shortening the grinding time of the ore.

[0005] Reference can also be made to a wet rapid ball mill disclosed in the prior art (Chinese patent application number CN02320095375.5, published on August 15, 2023), in which a push seat can be pushed back and forth by a linkage mechanism, and the push seat can push the material between the partition and the discharge port into the discharge port, and the material is crushed again by the cutting blade in the discharge port, and the material enters the ball mill body through the guide pipe, and the ball mill body quickly and efficiently mills small particles of material;

[0006] In addition, reference may be made to an electronic ceramic grinding body ball mill disclosed in the prior art (application number CN202210811122.3, Chinese patent publication date 2024-05-28), which miniaturizes a portion of the electronic ceramics. At this time, the fine particles pass through the small holes inside the sieve plate after the diameter reaches the required requirements, thereby automatically screening the particles in advance when they are crushed by the ball mill, preventing accumulation from causing buffering of the internal crushing force, extending the processing time, and accelerating the discharge efficiency.

[0007] Although the above-mentioned prior art can solve the problem of secondary crushing, when crushing, first during the processing, in order to overcome the dust generated during the processing, it is necessary to inject water into the internal position of the device, and the prior art lacks a mechanism for injecting water into the device, so there are still certain inconveniences during operation.

[0041] When using the device, first fill the water tank 19 with water, then put the tungsten carbide raw material into the secondary processing box 10 through the feed port 9, and then start the transmission box 2 to rotate the gear of the transmission box 2. Since the gear connected to the output end of the transmission box 2 is meshed with the rotating gear 3, the rotating gear 3 can drive the ball mill body 4 to rotate at the inner position of the support frame 1 through the rotating shaft connecting sleeve 101. At this time, the crushed material can be processed by the ball mill body 4, and the right end of the rotating gear 3 will be The transmission assembly 5 drives the connecting gear 6 to rotate, and the connecting gear 6 can be rotated at the outer position of the crushing box 8, and one side of the connecting gear 6 is meshed with the linkage gear 7, so that the crushing roller 21 fixedly connected with the linkage gear 7 and the connecting gear 6 rotates.

The piston block 26 draws up the water source inside the water tank 19 through the water storage pipe 22 and the water delivery pipe 20, and the water source will remain in the water storage pipe 22. When the piston block 26 moves to the left, due to the water delivery pipe 20 A one-way water inlet valve is arranged inside the water storage pipe 22, and the water source inside the water storage pipe 22 will not flow back. As the piston block 26 continues to move, the fitting cone block 27 will be deformed by the return spring 28. At this time, the water source will flow into the water supply channel 30 through the hole of the piston block 26. The water supply channel 30 is at the same axial position as the reciprocating screw rod 23 and the crushing roller 21, so that the water source can enter the crushing roller 21 and be sprayed through the pressure nozzle 31.
