Description

Technical Field

[0001] The present invention relates to the technical field of ore crushing equipment, and particularly to an ore ball milling device and a using method thereof. Background Art

[0002] In the process of mining, the useful minerals in the raw ore are often closely disseminated with gangue minerals. It is necessary to crush them to achieve sufficient dissociation before effective separation can be carried out. This process is called ore dressing. When carrying out ore dressing, it is first necessary to crush the ore raw materials. When carrying out crushing, an ore ball milling device is required.

[0003] In the prior art, when an ore ball mill is in use, first, appropriate grinding balls need to be added to the tank body of the ball mill. By rotating the ball mill, the grinding balls move and fall inside the tank body, impacting the ore raw materials inside the tank body to crush them, so as to achieve the crushing effect. However, in the actual use process, when carrying out ore dressing, ores with large size differences are usually directly added into the tank body. After the ores with large particle size differences enter the ball mill, due to the excessive difference in the particle sizes of the ores, the flow and grinding process of the materials become uneven. Large particle ores require more time and energy to be ground into fine particles, while fine particle ores are easily over-ground, affecting the quality of the final product and the working efficiency.

[0023] The screening assembly includes a plurality of vibration springs 21. The plurality of vibration springs 21 are correspondingly fixedly installed on the side surface of the guiding box 9. The upper sides of the plurality of vibration springs 21 are fixedly installed with the same blanking box 20. A screening plate 40 is fixedly installed on the inner wall of the blanking box 20. A lever 22 is fixedly installed on one side of the blanking box 20. A driving block 23 is fixedly installed at the bottom end of the lever 22. A sliding rod 24 is fixedly installed on one side of the feeding pipe 41. One end of the driving block 23 is slidably connected to the sliding rod 24. A driving unit is fixedly installed on one side of the stabilizing frame 2.

[0024] With the above structure, four stabilizing frames 2 are installed on the upper side of the base 1. Two of the stabilizing frames 2 are installed at both ends of the tank body 5, and the connection between them and the tank body 5 is rotationally installed by bearings to ensure that the tank body 5 can rotate normally. A grinding ball feeding port is provided on the surface of the tank body 5, and a sealing cover is fixedly installed on the grinding ball feeding port through a plurality of bolts, which is convenient for adding grinding balls into the tank body 5. The other two are installed on the lower side of the feeding pipe 41 to facilitate the reinforcement and stability of the feeding pipe 41. The inner cavity of the feeding pipe 41 is cylindrical, and the inner diameter size of the feeding pipe 41 is the same as that of the feeding pipe 8, which is convenient for better conveying of ore materials after rotational connection. One end of the feeding pipe 8 is connected to the feeding end of the tank body 5, and the feeding port of the feeding pipe 41 communicates with the guiding box 9. The guiding box 9 is trapezoidal in reverse and is vertically through. One side of it is provided with an inclined surface, which can concentrate the mineral materials so that they can better enter the feeding pipe 41 and be fed. Two mounting ears are installed on both sides of the guiding box 9, and a vibration spring 21 is installed on the upper side of each of the four mounting ears. The top ends of the four vibration springs 21 are fixedly installed with a blanking box 20 through a mounting ear.

The lever 22 on one side of the blanking box 20 is L-shaped, and its bottom end is fixedly connected to the driving block 23 and drives the lever 22 through the driving block 23. A circular ring is installed on one side of the driving block 23, and the circular ring is movably sleeved outside the sliding rod 24 and is slidably connected to the sliding rod 24 through the circular ring. The driving block 23 reciprocates to drive the blanking box 20 to shake horizontally left and right, so as to facilitate the screening of the ore.

[0025] Further, the driving unit includes two load-bearing blocks 13, which are correspondingly installed on one side of the stabilizing frame 2. A transmission rod 14 is rotatably installed on the upper sides of the two load-bearing blocks 13. A reciprocating ring 15 is fixedly sleeved outside the transmission rod 14. A reciprocating groove is opened on the lower side of the driving block 23, and the upper part of the reciprocating ring 15 is slidably arranged in the reciprocating groove. In this embodiment, the reciprocating ring 15 is a cam structure to push the driving block 23 to shake horizontally left and right.

[0026] With the above structure, bearings are installed at the top ends of the two load-bearing blocks 13 to facilitate the rotational connection of the transmission rod 14. The reciprocating ring 15 is installed between the two bearings. The reciprocating groove opened on the lower side of the driving block 23 is rectangular and fits on the surface of the reciprocating ring 15. When the reciprocating ring 15 rotates, it can push the driving block 23 to perform horizontal reciprocating motion through the reciprocating groove, so as to drive the blanking box 20 to shake through the lever 22.

[0027] Further, the driving unit further includes a first-stage transmission gear 12, which is fixedly installed at one end of the transmission rod 14. A toothed ring 11 is fixedly sleeved outside the feeding pipe 8, and the toothed ring 11 meshes with the first-stage transmission gear 12.

[0028] With the above structure, the number of teeth of the first-stage transmission gear 12 is less than that of the gear ring 11. When the feed pipe 8 rotates, it will drive the transmission rod 14 to rotate, and the rotation speed needs to be higher than that of the feed pipe 8, ensuring the conveying efficiency of the material.

[0029] Furthermore, a slide rail 29 is fixedly installed on one side of the guiding box 9. A limiting port is opened on one side of the slide rail 29. A limiting block 37 is slidably installed in the limiting port. A support rod 38 is fixedly installed on one side of the limiting block 37. A water tank 32 is fixedly installed at the top of the support rod 38. A water wheel 33 is rotatably installed in the water tank 32.

[0030] With the above structure, one side of the guiding box 9 is extended and installed with a slide rail 29 through two hexagonal blocks. A limiting port is opened on the side of the slide rail 29 away from the guiding box 9. The length of the limiting port is the same as the length of the upper part of the blanking box 20, facilitating the horizontal movement track of the limiting block 37 to cover the entire upper side of the blanking box 20. The support rod 38 fixedly installed on one side of the limiting block 37 is U-shaped, and the rotating rod 36 is rotatably installed therein. The inner part of the water tank 32 is a cylindrical cavity, and the water wheel 33 fits on its inner wall. A hose needs to be installed on the external connecting pipe 31 on one side of the water tank 32 when connecting to an external water source to prevent affecting the normal movement of the water tank 32. The shunt pipe 34 installed on the other side has a length the same as the width of the upper side of the blanking box 20, so that it can cooperate with the nozzles 35 installed at equal intervals on the lower side to spray water, inject water into the screened ore, and can also reduce dust while injecting water, improving environmental protection. The rotating rod 36 can drive the water wheel 33 at the top. The faster the rotating speed of the rotating rod 36, the faster the driving speed of the water wheel 33, and the faster the water injection rate, thereby dynamically controlling the water injection rate.

[0031] Furthermore, a connecting ear 27 is fixedly installed on one side of the feeding pipe 41. A connecting hole is opened on one side of the connecting ear 27. A reciprocating lead screw 26 is rotatably installed in the connecting hole. A reciprocating block 25 is externally screwed on the reciprocating lead screw 26.

A guiding gear 28 is fixedly installed at one end of the reciprocating lead screw 26. The guiding gear 28 meshes with the gear ring 11.

[0032] With the above structure, the reciprocating lead screw 26 is a prior art, and the length of the reciprocating lead screw 26 is equal to the length of the limit opening, which facilitates driving the support rod 38 through the reciprocating block 25 to make the support rod 38 reciprocate.

[0033] Furthermore, the feeding assembly includes an auger 17 rotatably installed in the rotating hole. One end of the auger 17 is fixedly installed with an auger gear 18, and one end of the transmission rod 14 is fixedly installed with an intermediate gear 16, and the intermediate gear 16 meshes with the auger gear 18.

[0034] With the above structure, the inner cross-section of the feeding pipe 41 is circular and is adapted to the auger 17, which facilitates the auger 17 to evenly feed the ore mixture.

[0035] Furthermore, a ball milling motor 4 is fixedly installed on the upper side of the base 1. The output end of the ball milling motor 4 is fixedly installed with a driving gear 3. The outer wall of the tank body 5 is fixedly installed with a ball milling gear 7, and the ball milling gear 7 meshes with the driving gear 3. A discharge port is opened at one end of the tank body 5 away from the feed pipe 8, and a discharge pipe 6 is fixedly installed in the discharge port.

[0036] With the above structure, the ball milling gear 7 is fitted on the tank body 5, and the ball milling gears 7 are installed at both ends of the tank body 5, and the installation positions of the driving gear 3 and the ball milling motor 4 can be changed according to the actual situation, and both can be normally driven by the ball milling motor 4.

[0037] Furthermore, a screening hopper 19 is fixedly installed on the lower side of the blanking box 20.

[0038] With the above structure, the screening hopper 19 is conical, and there is a certain distance between its surface and the opening on the upper side of the guiding box 9, and the bottom end of the screening hopper 19 extends into the guiding box 9, which can provide a moving space for the screening hopper 19 during the shaking screening process and prevent the ore materials from spilling.

[0039] Furthermore, a spiral blade 10 is fixedly installed on the inner wall of the feed pipe 8.

[0040] With the above structure, the spiral blade 10 is a prior art, and its length is the same as the length of the feed pipe 8. When the feed pipe 8 rotates, it cooperates with the spiral blade 10 to convey the ore raw materials.

[0041] Working principle: When the device is in use, first open the tank body 5, add grinding balls into the tank body 5 and close the tank body 5. Then connect the water source to the external connecting pipe 31 using a hose. Subsequently, pour the ore to be processed and beneficiated into the feeding box 20, start the ball mill motor 4, and begin the processing. The output end of the ball mill motor 4 drives the driving gear 3 to rotate. The driving gear 3 drives the ball mill gear 7 to rotate. The ball mill gear 7 drives the tank body 5 to rotate. The tank body 5 drives the feeding pipe 8 to rotate. The feeding pipe 8 drives the toothed ring 11 to rotate. The toothed ring 11 drives the transmission rod 14 to rotate through the first-stage transmission gear 12. The transmission rod 14 drives the reciprocating ring 15 to rotate. The reciprocating ring 15 drives the driving block 23 to perform horizontal reciprocating motion along the sliding rod 24. The driving block 23 drives the lever 22 to reciprocate. The lever 22 drives the feeding box 20 to perform horizontal reciprocating motion. Under the action of multiple vibration springs 21, the ore in the feeding box 20 rolls horizontally and is screened in cooperation with the screening plate 40.

[0042] During the screening process, the toothed ring 11 simultaneously drives the guiding gear 28 to rotate. The guiding gear 28 drives the reciprocating screw rod 26 to rotate. The reciprocating screw rod 26 drives the reciprocating block 25 to move. The reciprocating block 25 drives the support rod 38 to move. Under the action of the slide rail 29 and the limit block 37, the support rod 38 performs horizontal reciprocating motion. The support rod 38 drives the water tank 32 to move horizontally. The water tank 32 drives the shunt pipe 34 to reciprocate. The ore is injected with water through multiple nozzles 35 on the shunt pipe 34. During the water injection process, the support rod 38 drives the rotating rod 36 to move and rotates under the combined action of the self-rotating gear 39 and the rack 30. The rotation of the rotating rod 36 drives the water wheel 33 to perform adaptive rotation to control the water source flow rate, thereby dynamically adjusting the inflow of the water source through the rotation speed of the tank body 5.

[0043] After screening, the ore is mixed with water and enters the guiding box 9 through the screening hopper 19, and enters the feeding pipe 41 through the guiding box 9. At this time, the transmission rod 14 drives the middle gear 16 to rotate. The middle gear 16 drives the auger gear 18 to rotate. The auger gear 18 drives the auger 17 to rotate, and evenly feeds the mixture of ore and water into the feeding pipe 8, and is conveyed to the inside of the tank body 5 through the spiral blade 10 in the feeding pipe 8. The ore is ground by the rolling of the tank body 5 and the grinding balls inside the tank body 5 to be crushed into pulp. These pulps overflow and are discharged through the discharge pipe 6 at the other end of the tank body 5 to complete the ore grinding process.

[0044] The present invention also provides a method for using an ore ball mill device, including the following specific steps: S1. First, open the tank body 5, add grinding balls into the tank body 5 and close the tank body 5. Then connect the water source to the external connecting pipe 31 using a hose. Subsequently, pour the ore into the feeding box 20, start the ball mill motor 4, and begin the processing; S2. The output end of the ball milling motor 4 drives the driving gear 3 to rotate. The driving gear 3 drives the ball milling gear 7 to rotate. The ball milling gear 7 drives the tank body 5 to rotate. The tank body 5 drives the feed pipe 8 to rotate. The feed pipe 8 drives the gear ring 11 to rotate. The gear ring 11 drives the screening assembly to screen the ore through the first-stage transmission gear 12, screen out the ore of appropriate size, and enter the feed pipe 8 through the guiding box 9, and convey the screened ore through the conveying assembly, so that it enters the tank body 5 through the spiral blade 10 in the feed pipe 8 and is crushed in cooperation with the grinding balls; S3. During the screening process, the guiding gear 28 is driven to rotate simultaneously by the gear ring 11. The guiding gear 28 drives the reciprocating lead screw 26 to rotate. The reciprocating lead screw 26 drives the reciprocating block 25 to move reciprocally. During the movement process, the rotating rod 36 is driven to rotate through the rack 30 and the self-rotating gear 39. The rotating rod 36 drives the water wheel 33 to rotate, and the water source is controlled to add water evenly adaptively according to the rotation speed of the tank body 5, so as to continuously supplement the water source inside the tank body 5; S4. The ore after ore grinding is discharged along with the pulp through the discharge pipe 6 of the tank body 5 to complete the ore grinding process of ore dressing.
