A crushing device for mineral processing

Abstract

This utility model relates to the field of crushing device technology and discloses a crushing device for mineral processing. This utility model solves the problem that the crushing device cannot guarantee the continuous uniformity of the feed during use, which leads to easy wear and reduced service life. Multiple fixed plates divide the interior of the crushing box into multiple independent spaces, and the ore can be screened through the screening trough. Smaller ores pass directly, while larger ores are temporarily retained in the space. The rotating shaft is driven by a servo motor, which in turn drives the multiple fixed plates to rotate around the axis of the rotating shaft. This allows the large ores to fill one space and then wait to enter the next space, thus ensuring the stage uniformity of the ore. At the same time, the uniformization mechanism also drives the first crushing roller to rotate, which performs preliminary crushing of the ore in the space and further maintains the good condition of the second and third crushing rollers.

Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, specifically a crushing equipment for mineral processing. Background Technology

[0002] In the mining process, crushing and screening the mined raw ore is a very important part of the mining process. The existing devices for crushing raw ore are mainly jaw crushers and roller crushers. For example, the existing Chinese patent with publication number CN216964890U discloses a crushing device for mineral processing. The ore enters the first box from the feed bin and falls between two sets of first crushing rollers to achieve the first crushing of the ore.

[0003] The ore is fed into the feed hopper in a very uneven manner, often resulting in periods of ore aggregation or dispersion. This causes the two sets of first crushing rollers to struggle when crushing aggregated ore, and they are also prone to wear and tear, which in turn increases the gaps between them, thus reducing crushing efficiency and resulting in poor crushing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a crushing device for mineral processing. By using this device, the problem of the crushing device being prone to wear and reduced service life due to the inability to guarantee the continuous uniformity of the feed during use is solved.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for mineral processing, comprising a crushing box, an internal receiving component and a crushing assembly, the crushing assembly including a homogenizing mechanism, a crushing roller one meshing on one side of the homogenizing mechanism, a crushing roller two connected to the outer side of the homogenizing mechanism via a transmission belt, and a crushing roller three meshing on one side of the crushing roller two; the homogenizing mechanism includes a servo motor fixedly connected to the crushing box and a rotating shaft fixedly installed at the output end of the servo motor, the rotating shaft passing through the crushing box and rotatably connected, multiple fixing plates fixedly installed on the outer surface of the rotating shaft, and screening grooves penetrating through the interior of the fixing plates, so that when the ore enters the crushing box, it will first contact the receiving component and be buffered, avoiding continuous damage to the homogenizing mechanism. To mitigate impact damage, multiple fixed plates divide the interior of the crushing box into several independent spaces. First, the ore is screened through a screening trough. Smaller pieces are directly crushed by crushing rollers two and three, while larger pieces remain temporarily in the space. Then, a servo motor drives a rotating shaft, which in turn rotates multiple fixed plates around the shaft's axis. This ensures that large pieces of ore, once filling one space, wait to enter the next, maintaining the uniformity of the ore's stages. This reduces the wear rate of crushing rollers two and three, extending their service life. Simultaneously, the uniformization mechanism also drives crushing roller one to rotate, performing preliminary crushing of the ore in the space, further maintaining the good condition of crushing rollers two and three.

[0006] Preferably, a gear one is fixedly installed on the outer side of the rotating shaft, and the crushing roller one includes a driven rod that passes through the crushing box and is rotatably connected. A gear two is fixedly installed at one end of the driven rod, and the gear two meshes with the gear one. Multiple sets of crushing teeth are fixedly installed on the outer side of the driven rod. During the rotation of the rotating shaft, the gear one is driven to rotate. Since the gear two is meshed with the gear one, the gear two drives the driven rod to rotate, so that the multiple sets of crushing teeth perform preliminary crushing on larger ores, thereby improving crushing efficiency and enhancing crushing effect.

[0007] Preferably, both the second and third crushing rollers pass through the crushing box and are rotatably connected. Gears are fixedly installed on the outer side of one end of both the second and third crushing rollers and are meshed together. When the rotating shaft rotates, it drives the second crushing roller to rotate through the transmission belt. Since the two sets of gears are meshed, the second crushing roller drives the third crushing roller to rotate when it rotates, thereby performing secondary crushing on the ore that has been initially crushed, ensuring the crushing effect, and preventing premature wear, thus extending its service life.

[0008] Preferably, the receiving component includes a buffer plate and telescopic rods located at the four corners of the lower end of the buffer plate and fixedly connected. A connecting plate is fixedly installed at the lower end of the telescopic rod, and the connecting plate is fixedly connected to the inner wall surface of the crushing box. A spring is sleeved on the outer side of the telescopic rod. The upper end of the spring is fixedly connected to the buffer plate, and the lower end of the spring is fixedly connected to the connecting plate. After the ore enters the crushing box, it first contacts the buffer plate, and the compression of the spring achieves the effect of buffering and releasing force. Then the ore will roll down from both sides of the buffer plate along its surface, effectively avoiding direct impact of the ore on the uniform mechanism.

[0009] Preferably, a guide plate is fixedly installed at the lower end of the connecting plate. The guide plate ensures that the larger ore particles will fill one space first before filling the next space, thus ensuring the normal operation of the uniform mechanism.

[0010] Preferably, one of the guide plates is fixedly mounted with a toothed rack, and another toothed rack is fixedly mounted on one side of the fixed plate. During the rotation of the multiple fixed plates around the axis of rotation, the second toothed rack will cooperate with the first toothed rack to achieve a shearing effect, thus preventing larger pieces of ore from getting stuck on the fixed plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This utility model proposes a crushing device for mineral processing. When ore enters the crushing box, it first contacts and is buffered by the receiving component to avoid continuous impact damage to the homogenizing mechanism. Multiple fixed plates divide the interior of the crushing box into multiple independent spaces. The ore is first screened through a screening trough. Smaller ore is directly crushed by crushing rollers two and three, while larger ore is temporarily held in the space. Then, a servo motor drives the rotating shaft to rotate, which in turn drives multiple fixed plates to rotate around the axis of the rotating shaft. This allows the large ore to fill one space and then wait to enter the next space, thus ensuring the stage uniformity of the ore and reducing the wear rate of crushing rollers two and three, thereby extending their service life. At the same time, the homogenizing mechanism also drives crushing roller one to rotate, performing preliminary crushing of the ore in the space, further maintaining the good condition of crushing rollers two and three.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figure 1-3 , Figure 5 A crushing device for mineral processing includes a crushing box 1. The crushing box 1 is provided with a receiving component 2 and a crushing assembly 3. The crushing assembly 3 includes a homogenizing mechanism 31. A crushing roller 32 is engaged on one side of the homogenizing mechanism 31. A crushing roller 34 is connected to the outside of the homogenizing mechanism 31 through a transmission belt 33. A crushing roller 35 is engaged on one side of the crushing roller 34.

[0022] The homogenizing mechanism 31 includes a servo motor 311 fixedly connected to the crushing box 1 and a rotating shaft 312 fixedly installed at the output end of the servo motor 311. The rotating shaft 312 passes through the crushing box 1 and is rotatably connected. Multiple fixing plates 313 are fixedly installed on the outer surface of the rotating shaft 312. Screening grooves 314 are opened through the interior of the fixing plates 313. When the ore enters the interior of the crushing box 1, it will first come into contact with the receiving part 2 and be buffered to avoid continuous impact damage to the homogenizing mechanism 31. The multiple fixing plates 313 divide the interior of the crushing box 1 into multiple independent spaces. The ore can be screened first through the screening grooves 314. Smaller ore can be directly screened. Crushing rollers 2 (34) and 3 (35) perform crushing, while larger pieces of ore are temporarily left in the space. Then, the servo motor 311 drives the rotating shaft 312 to rotate, which in turn drives multiple fixed plates 313 to rotate around the axis of the rotating shaft 312. This allows the large ore to fill one space and then wait to enter the next space, thus ensuring the uniformity of the ore at each stage. This reduces the wear rate of crushing rollers 2 (34) and 3 (35) and extends their service life. At the same time, the uniformizing mechanism 31 also drives crushing roller 1 (32) to rotate, which performs preliminary crushing of the ore in the space, further maintaining the good condition of crushing rollers 2 (34) and 3 (35).

[0023] Combination Figure 5 A gear 316 is fixedly installed on the outer side of the rotating shaft 312. The crushing roller 32 includes a driven rod 322 that passes through the crushing box 1 and is rotatably connected. A gear 321 is fixedly installed at one end of the driven rod 322. The gear 321 meshes with the gear 316. Multiple sets of crushing teeth 323 are fixedly installed on the outer side of the driven rod 322. During the rotation of the rotating shaft 312, the gear 316 is driven to rotate. Since the gear 321 is meshed with the gear 316, the gear 321 drives the driven rod 322 to rotate, so that the multiple sets of crushing teeth 323 perform preliminary crushing on larger ores, thereby improving crushing efficiency and crushing effect.

[0024] Combination Figure 5 Both crushing roller 2 34 and crushing roller 35 pass through crushing box 1 and are rotatably connected. Gear 341 is fixedly installed on the outer side of one end of crushing roller 2 34 and crushing roller 35 and meshes with it. When rotating shaft 312 rotates, it drives crushing roller 2 34 to rotate through transmission belt 33. Since the two sets of gear 341 are meshed, crushing roller 2 34 drives crushing roller 35 to rotate when it rotates, thereby performing secondary crushing on the ore that has been initially crushed, ensuring the crushing effect, and preventing premature wear, thus extending its service life.

[0025] Combination Figure 4The receiving component 2 includes a buffer plate 21 and telescopic rods 22 located at the four corners of the lower end of the buffer plate 21 and fixedly connected. A connecting plate 23 is fixedly installed at the lower end of the telescopic rod 22. The connecting plate 23 is fixedly connected to the inner wall surface of the crushing box 1. A spring 24 is sleeved on the outer side of the telescopic rod 22. The upper end of the spring 24 is fixedly connected to the buffer plate 21, and the lower end of the spring 24 is fixedly connected to the connecting plate 23. After the ore enters the crushing box 1, it first contacts the buffer plate 21. The compression of the spring 24 plays a role in buffering and releasing force. Then the ore will roll down from both sides of the buffer plate 21 along its surface, effectively avoiding the direct impact of the ore on the uniform mechanism 31.

[0026] Combination Figure 4 A guide plate 25 is fixedly installed at the lower end of the connecting plate 23. The guide plate 25 ensures that the larger ore aggregates fill one space first, and then fill the next space, thus ensuring the normal operation of the uniform mechanism 31.

[0027] Combination Figure 4-5 One of the guide plates 25 has a toothed rack 26 fixedly installed on its surface, and a toothed rack 315 is fixedly installed on one side of the fixed plate 313. When the multiple fixed plates 313 rotate around the axis of the rotating shaft 312, the toothed rack 315 will cooperate with the toothed rack 26 to achieve a shearing effect, so as to prevent larger ore from getting stuck on the fixed plate 313.

[0028] The specific working process and principle of this utility model are as follows: After the ore enters the crushing box 1, it first contacts the buffer plate 21. The compression of the spring 24 buffers and releases the force. Then, the ore rolls down the surface of the buffer plate 21 from both sides and falls down the guide plate 25 into one of the spaces formed by multiple fixed plates 313. The ore is then screened by the screening trough 314. Smaller pieces are directly crushed by the crushing rollers 34 and 35, while larger pieces are temporarily left in the space. The servo motor 311 drives the rotating shaft 312 to rotate, which in turn drives the multiple fixed plates 313 to rotate around the axis of the rotating shaft 312. This allows the large ore to accumulate and fill one of the spaces. The ore will then wait to enter the next space, thus ensuring the uniformity of the ore stages. At the same time, the rotating shaft 312 drives the gear 1 316 to rotate during the rotation. Since the gear 2 321 is meshed with the gear 1 316, it drives the driven rod 322 to rotate, so that multiple sets of crushing teeth 323 perform preliminary crushing on larger ore. While the rotating shaft 312 is rotating, it drives the crushing roller 2 34 to rotate through the transmission belt 33. Since the two sets of gear 341 are meshed, the crushing roller 2 34 drives the crushing roller 35 to rotate when it rotates, thus performing secondary crushing on the ore that has been initially crushed, ensuring the crushing effect, and preventing premature wear, thereby extending its service life.
