Technical Field

[0001] The utility model relates to the technical field of crushers, in particular to a circulating ore crusher. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components in the ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams and tons, and other ores are often expressed in percentages. Ore grade is often used to measure the value of ore, but the composition of the gangue and the amount of harmful impurities in the ore of the same effective component also affect the value of the ore. After the ore is mined, it needs to be crushed. Most of the existing crushers only crush the ore once, resulting in some ores being relatively large in volume and needing to be crushed twice.

A first connecting shaft 10 is fixedly mounted at the center of the rotating shell 9. The first connecting shaft 10 passes through the inner shell 8 and extends into the inner shell 8. A plurality of transfer cavities 11 are provided between the rotating shell 9 and the inner shell 8. A second connecting shaft 13 is fixedly mounted on one end of the crushing roller 2, and one end of the second connecting shaft 13 extends into the inner shell 8. A driving gear 12 is mounted on one end of the second connecting shaft 13, and a driven gear 18 is mounted on one end of the first connecting shaft 10. The driving gear 12 is meshed with the driven gear 18. When in use, the number of teeth of the driving gear 12 should be less than the number of teeth of the driven gear 10. The attached figure is only used for illustration and does not represent its actual size. The ore enters between the two crushing rollers 2 from the top feed port of the shell 1. The driving motor 6 drives the crushing rollers 2 to rotate and crush the ore. After crushing, the ore falls from the gap between the two crushing rollers 2. The falling ore is filtered and screened by the filter rod 5. The fine material of composite specifications falls from the filter plate 5 and is discharged from the discharge port below. The ore that does not meet the specifications is discharged from the shell 1 from the lowest discharge hole 4 on the right side of the inclined filter plate 5 and enters the transfer chamber 11. At the same time, the crushing roller 2 The rotation drives the second connecting shaft 13 to rotate, the rotation of the second connecting shaft 13 drives the driving gear 12 to rotate, the rotation of the driving gear 12 drives the driven gear 18 to rotate, the rotation of the driven gear 13 drives the first connecting shaft 10 to rotate, the rotation of the first connecting shaft 10 drives the rotating shell 9 to rotate, as the rotating shell 9 rotates, the transfer chamber 11 carrying ore rotates with the rotating shell 9 until it is flush with the return hole 3, the ore in the transfer chamber 11 slides from the transfer chamber 11, and enters the outer shell 1 (the space above the crushing roller 2) along the return hole 3, and then the ore is crushed in a cycle until the crushed ore meets the composite specification requirements.

[0028] By setting up a circulation mechanism including an inner shell 8, a rotating shell 9, a first connecting shaft 10, a transfer chamber 11, a driving gear 12, a second connecting shaft 13 and a driven gear 18, the ore that does not meet the specification requirements can be put back into the outer shell 1 for crushing, and only one power source, the drive motor 6, is needed to drive the entire crusher to operate, thereby simplifying the control system and facilitating maintenance.

[0029] Embodiment 2:

[0030] like Figure 3-4 As shown, a plurality of partitions 14 are evenly installed in the rotating shell 9 , and the plurality of partitions 14 evenly divide the rotating shell 9 into a plurality of transfer chambers 11 .

[0031] By evenly installing a plurality of partitions 14 in the rotating shell 9 , the rotating shell 9 can be evenly divided into a plurality of transfer chambers 11 .

[0032] Embodiment 3:

[0033] like Figure 3-5 As shown, a sealing ring 15 is installed on the side of the rotating shell 9 close to the outer shell 1, and one side of the sealing ring 15 is connected to the partition 14. The gap between the sealing ring 15 and the partition 14 forms a channel opening for the ore to pass through. When in use, after the ore is discharged from the discharge hole 4, it enters the transfer chamber 11 from the channel opening of the lowermost transfer chamber 11. Due to the interception of the sealing ring 15, the ore does not contact the outer shell 1, reducing the wear of the outer shell 1. When the transfer chamber 11 rotates to the uppermost position (the highest point), the ore is discharged from the transfer chamber 11 from the channel opening and returns to the outer shell 1 from the return hole 3.

[0034] By providing the sealing ring 15 , the ore entering the transfer chamber 11 can be isolated from the outer shell 1 , thereby reducing the wear rate and extending the service life of the outer shell 1 .

[0035] Embodiment 4:

[0036] like Figure 3-5 As shown, a sealing ring 17 is installed on the inner side of the partition 14, and the sealing ring 17 is located on the outer side of the inner shell 8. When in use, the sealing ring 17 separates the ore in the transfer chamber 11 from the inner shell 8, thereby reducing the wear of the inner shell 8 and extending its service life.

[0037] By installing the sealing ring 17 on the inner side of the partition 14, the wear of the inner shell 8 can be reduced and its service life can be extended.

[0038] Embodiment 5:

[0039] like Figure 3-5 As shown, a guide plate 16 is installed obliquely in the transfer chamber 11. When in use, when the transfer chamber 11 is located at the lowest point, the guide plate 16 is inclined outward (the side away from the shell 1 is lower than the other side), so that the ore entering the transfer chamber 11 is concentrated on the outside of the transfer chamber 11 (the side away from the shell 1 is lower than the other side). When the transfer chamber 11 rotates to the highest point, the side of the guide plate 16 away from the shell 1 is higher than the other side, so that the ore in the transfer chamber 11 slides toward the passage along the inclined guide plate 16, thereby reducing the ore residue in the transfer chamber 11, which is conducive to the discharge of the ore from the transfer chamber 11.

[0040] By arranging the guide plate 16 to be obliquely installed in the transfer chamber 11 , it is possible to facilitate the discharge of ore from the transfer chamber 11 and reduce the amount of ore residue in the transfer chamber 11 .

[0041] Working principle: When in use, the number of teeth of the driving gear 12 should be less than the number of teeth of the driven gear 10. The attached figure is only used for illustration and does not represent its actual size. The ore enters between the two crushing rollers 2 from the top feed port of the shell 1. The driving motor 6 drives the crushing rollers 2 to rotate and crush the ore. After crushing, the ore falls from the gap between the two crushing rollers 2. The falling ore is filtered and screened by the filter rod 5. The fine material of composite specifications falls from the filter plate 5 and is discharged from the discharge port below. The ore that does not meet the specifications is discharged from the shell 1 from the lowest discharge hole 4 on the right side of the inclined filter plate 5 and enters the transfer chamber 11. At the same time, the crushing The rotation of the roller 2 drives the second connecting shaft 13 to rotate, the rotation of the second connecting shaft 13 drives the driving gear 12 to rotate, the rotation of the driving gear 12 drives the driven gear 18 to rotate, the rotation of the driven gear 13 drives the first connecting shaft 10 to rotate, the rotation of the first connecting shaft 10 drives the rotating shell 9 to rotate, as the rotating shell 9 rotates, the transfer chamber 11 carrying ore rotates with the rotating shell 9 until it is flush with the return hole 3, the ore in the transfer chamber 11 slides from the transfer chamber 11, and enters the outer shell 1 (the space above the crushing roller 2) along the return hole 3, and then the ore is crushed in a cycle until the crushed ore meets the composite specification requirements.
