Abstract
Description
Technical Field
[0001] This utility model relates to the field of ore processing technology, and in particular to an ore crushing device. Background Technology
[0002] A classifying crusher is a common piece of equipment used for crushing ores and rocks. It breaks down large materials into smaller particles through a grading process, and is widely used in mining, metallurgy, and construction industries. Currently, in the operation of classifying crushers, the ore from the upper stage is further crushed in the lower stage. After the upper stage crushing, some of the ore has reached the target particle size, but this qualified ore still enters the lower stage crushing for further crushing along with the unqualified ore. This not only increases the crushing burden on the equipment but also leads to over-crushing of the ore. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a crushing device for ore, thereby solving the problems described above.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A crushing device for ore includes a crushing box, a primary crushing mechanism, and a secondary crushing mechanism. The crushing box has a feed inlet and is mounted on a support. The primary and secondary crushing mechanisms are installed inside the crushing box. A first vibrating screen is installed below the primary crushing mechanism. A conveying channel is provided inside the crushing box. The feed end of the conveying channel is located below the first vibrating screen, and the output end of the conveying channel extends out of the bottom of the crushing box. A trough is provided on the crushing box. The output end of the first vibrating screen extends above the trough, and the output end of the trough is located above the secondary crushing mechanism. A second vibrating screen is installed below the secondary crushing mechanism. A screw conveyor is installed on one side of the crushing box. The second vibrating screen conveys tailings to the input end of the screw conveyor, and the screw conveyor conveys tailings to the trough. A guide chute is connected inside the crushing box and communicates with the conveying channel.
[0006] Preferably, the material conveying channel includes a guide hopper and a channel, the guide hopper is connected to the channel, and the guide hopper is located below the first vibrating screen.
[0007] Preferably, the primary crushing mechanism and the secondary crushing mechanism each include a first crushing roller, a second crushing roller, and a driving mechanism. The two ends of the first crushing roller and the second crushing roller are rotatably connected to the crushing box, and the driving mechanism is used to drive the first crushing roller and the second crushing roller to rotate.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] After being crushed by the primary crushing mechanism, the ore with the correct particle size can be directly output through the conveying channel without needing to be crushed again by the secondary crushing mechanism. This reduces the energy consumption and wear of the equipment and avoids over-crushing of the ore with the correct particle size, thus preventing ore waste and improving the pass rate of ore crushing. The ore with the incorrect particle size can be crushed again by the secondary crushing mechanism to further improve the pass rate of ore crushing. Attached Figure Description

[0012] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.
[0013] Example
[0014] See Figure 1This utility model provides an ore crushing device, including a crushing box 1, a primary crushing mechanism 2, and a secondary crushing mechanism 3. The crushing box 1 has an inlet 6 for feeding ore to be crushed into the primary crushing mechanism 2. The crushing box 1 is mounted on a support 8 for support. The primary crushing mechanism 2 and the secondary crushing mechanism 3 are installed inside the crushing box 1. A first vibrating screen 9 is located below the primary crushing mechanism 2. A conveying channel 10 is provided inside the crushing box 1. The inlet end of the conveying channel 10 is located below the first vibrating screen 9, and the outlet end of the conveying channel 10 extends beyond the bottom of the crushing box 1. A trough 14 is provided on the crushing box 1, and the outlet end of the first vibrating screen 9 extends above the trough 14. The first vibrating screen 9 screens the ore from the crushing mechanism. Ore with acceptable particle size falls into the conveying channel 10 after being screened by the first vibrating screen 9, avoiding further crushing of the ore with acceptable particle size, reducing the workload of the equipment, and improving the ore crushing qualification rate. Ore with unacceptable particle size... The material is fed into the feed trough 14 through the output end of the first vibrating screen 9. The output end of the feed trough 14 is located above the secondary crushing mechanism 3. The secondary crushing mechanism 3 further crushes the ore that does not meet the particle size requirements. A second baffle 18 is connected to the bottom of the first vibrating screen 9, allowing the ore with the correct particle size to fall effectively into the conveying channel 10 below. A second vibrating screen 15 is installed below the secondary crushing mechanism 3. A screw conveyor 16 is installed on one side of the crushing box 1. 5. The tailings are transported to the input end of the screw conveyor 16, which then transports them to the trough 14. The crushing box 1 is connected to a guide trough 17, which is connected to the conveying channel 10. After being crushed by the secondary crushing mechanism 3, the ore with the correct particle size falls into the guide trough 17 and is then fed into the conveying channel 10. The ore with the incorrect particle size is transported to the trough 14 by the screw conveyor 16, and then transported to the secondary crushing mechanism 3 for further crushing.
[0015] The material conveying channel 10 includes a guide hopper 11 and a channel 12. The guide hopper 11 is connected to the channel 12. The guide hopper 11 is located below the first vibrating screen 9. The guide hopper 11 can collect ore with qualified particle size after screening by the first vibrating screen 9 and guide the ore into the channel 12. A through groove 13 is provided on one side of the channel 12. The guide groove 17 is connected to the through groove 13 on the channel 12.
[0016] The crushing box 1 is equipped with a first baffle 7, which is located between the conveying channel 10 and the secondary crushing mechanism 3. This baffle 7 can prevent ore with unqualified particle size from splashing into the feed chute 17 when the secondary crushing mechanism 3 is crushing.
[0017] The primary crushing mechanism 2 and the secondary crushing mechanism 3 each include a first crushing roller 4, a second crushing roller 5, and a driving mechanism (not shown). The two ends of the first crushing roller 4 and the second crushing roller 5 are rotatably connected to the crushing box 1. The driving mechanism is used to drive the first crushing roller 4 and the second crushing roller 5 to rotate. The driving mechanism (not shown) is existing technology. The first crushing roller 4 and the second crushing roller 5 cooperate to crush the ore.
[0018] In operation, the ore is fed into the primary crushing mechanism 2 through the feed inlet 6. The primary crushing mechanism 2 crushes the ore, and the crushed ore falls onto the first vibrating screen 9. The first vibrating screen 9 screens the ore, and ore with qualified particle size falls into the conveying channel 10 below. Ore with unqualified particle size is conveyed to the secondary crushing mechanism 3 through the output end of the first vibrating screen 9. The secondary crushing mechanism 3 crushes the ore with unqualified particle size a second time, and the crushed ore falls onto the second vibrating screen 15. The second vibrating screen 15 screens the ore, and ore with qualified particle size falls into the guide chute 17 below. The guide chute 17 conveys the ore to the conveying channel 10, and ore with unqualified particle size is conveyed to the screw conveyor 16 through the output end of the first vibrating screen 9. The screw conveyor 16 conveys the ore with unqualified particle size to the trough 14, and the ore output from the trough 14 is crushed again by the secondary crushing mechanism 3.
