An environmentally friendly mining mill

Abstract

This invention discloses an environmentally friendly ore mill, including a support component, a mill body, and a feeding component. The support component includes a bottom hole frame, which is horizontally arranged, and a support frame is vertically fixed on the bottom surface of the bottom hole frame. The support frame is fixed to a mounting base by bolts. A support frame is horizontally arranged on the top surface of the bottom hole frame and is vertically slidably mounted on the bottom hole frame. Two rotating plates are symmetrically and vertically fixed on both sides of the top surface of the support frame. This invention overcomes the problem that existing crushing methods require multiple continuous impacts from steel balls to complete the crushing process. Each impact occurs at a different location, resulting in varying numbers of impacts on the ore at different locations, leading to a longer crushing time. This necessitates prolonged operation of the mill to rotate the ore, resulting in high energy consumption and reduced crushing efficiency. Furthermore, the dust generated by the steel ball impacts during ore crushing is discharged from the inlet and outlet hollow shafts, affecting the surrounding processing environment.

Description

Technical Field

[0001] This invention relates to the field of mining mill technology, and in particular to an environmentally friendly mining mill. Background Technology

[0002] Grinding mills are widely used in the mineral processing industry. There are many types of grinding mills, which can be classified according to the grinding media, such as ball mills, rod mills, autogenous mills, and semi-autogenous mills. Among them, ball mills and rod mills are the most widely used mining mills in mineral processing plants. Ball mills are key equipment for further grinding materials after they have been crushed. This type of grinding mill uses a certain number of steel balls as grinding media inside its cylinder. A ball mill consists of a horizontal cylinder, hollow inlet and outlet shafts, and grinding heads. Gears are located around the ends of the cylinder, and a gear meshes with the end of the drive motor. The meshing of the gears drives the cylinder to rotate.

[0003] During use, the ore is added or discharged from the inlet and outlet hollow shafts. Steel balls and ore are added to the inside of the mill at the same time. The rotation of the mill itself drives the steel balls and ore to move in a circular motion. During the motion, the steel balls and ore fall under the action of gravity. When they fall, the steel balls hit the ore and crush it.

[0004] However, the aforementioned ore mill uses the impact of steel balls to crush the ore. The mill primarily relies on the gravity of the falling steel balls to pulverize the ore. This pulverization method requires multiple consecutive impacts from the steel balls to complete the crushing process. Each impact occurs at a different location, and the number of impacts varies depending on the location of the ore, resulting in a longer pulverization time. This necessitates prolonged operation of the mill to rotate the ore, leading to high energy consumption and reduced pulverization efficiency. Furthermore, the dust generated by the steel ball impacts during ore crushing is discharged from the inlet and outlet hollow shafts, impacting the surrounding processing environment. Summary of the Invention

[0005] The purpose of this invention is to provide an environmentally friendly mining mill that aims to improve the aforementioned problems.

[0006] This invention is implemented as follows:

[0007] An environmentally friendly mining mill includes a support component, a mill body, and a feeding component. The support component includes a bottom hole frame, which is horizontally positioned, and a support frame is vertically fixed on the bottom surface of the bottom hole frame. The support frame is fixed to a mounting base by bolts. A support frame is horizontally positioned on the top surface of the bottom hole frame and is vertically slidably mounted on the bottom hole frame. Two rotating plates are symmetrically and vertically fixed on both sides of the top surface of the support frame. The mill body includes a grinding cylinder, which is horizontally rotatably connected between the two rotating plates. A liner is installed on the inner circumference of the grinding cylinder. An impact component is installed inside the grinding cylinder. A feeding component is installed on one side of the support frame and is used to feed material into the grinding cylinder.

[0008] Furthermore, a feeding cylinder is horizontally fixed at the center of one end face of the grinding cylinder, and a guide cylinder is horizontally fixed at the center of the other end face of the grinding cylinder. The feeding cylinders and guide cylinders at both ends of the grinding cylinder pass through two rotating plates, and the feeding cylinders and guide cylinders at both ends of the grinding cylinder are rotatably connected to the two rotating plates through bearings. Multiple fixing holes are evenly opened through the outer circumference of the grinding cylinder, and a feeding screw is vertically fixed through the outer circumference of the grinding cylinder. A screw plug is installed in the thread of the feeding screw.

[0009] Furthermore, a driven gear ring is fixed on the outer circumference of the feeding cylinder, and a drive motor is horizontally fixed on the vertical end face of the rotating plate on the side of the support frame near the feeding cylinder. The output end of the drive motor is fixed with a drive gear, and the drive gear meshes with the driven gear ring.

[0010] Furthermore, multiple guide posts are fixed on the outer circumference of the liner, and these guide posts are installed through the fixing holes of the grinding cylinder. The ends of the guide posts are fixed with studs, and nuts are installed on the studs.

[0011] Furthermore, the impact component includes a guide plate, which is slidably installed in the guide cylinder and is horizontally rotatably connected to a rotating shaft. The rotating shaft is horizontally inserted into the interior of the grinding cylinder, and multiple rotating rings are horizontally fixed on the outer circumference of the rotating shaft. Multiple chains are evenly fixed on the outer circumference of the rotating rings, and an impact ball is fixed at the other end of each chain. A stopper block is fixed at the end of the rotating shaft near the feeding cylinder.

[0012] Furthermore, a bracket is horizontally fixed on the outer end face of the guide cylinder of the grinding cylinder, and a hydraulic cylinder is horizontally fixed on the bracket. A push frame is horizontally fixed on the guide plate, and the push frame is fixedly connected to the output end of the hydraulic cylinder. A counterattack motor is horizontally fixed on the outer end face of the guide plate, and the output end of the counterattack motor is fixed to the end of the rotating shaft.

[0013] Furthermore, a pin is vertically fixed on the bottom surface of the support frame, and the pin is vertically slidably inserted into the through hole of the bottom hole frame. A spring damping shock absorber is vertically fixed on the bottom surface of the support frame, and the bottom end of the spring damping shock absorber is fixed on the top surface of the bottom hole frame.

[0014] Furthermore, the feeding component includes a slide bar seat, which is horizontally arranged on the side of the support frame near the feeding cylinder, and one end of the slide bar seat is fixed on the support frame. A support is vertically arranged on the slide bar seat, and a slider is fixed on the bottom surface of the support. The slider is horizontally slidably installed on the slide bar seat. A push rod is vertically fixed on the top surface of the support, and a feeding cylinder is horizontally fixed through the top of the support.

[0015] Furthermore, the conveying cylinder has an opening at one end near the feeding cylinder, and a guide cylinder is vertically fixed on the top of the outer circumference of the conveying cylinder away from the feeding cylinder. A conveying screw is horizontally arranged inside the conveying cylinder, and the end of the conveying screw is rotatably connected to the end face of the conveying cylinder. A conveying motor is horizontally fixed at the end of the conveying cylinder, and the output end of the conveying motor is fixed to the end of the conveying screw.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] During use, after the ore is added to the grinding cylinder, the hydraulic cylinder on the support at one end of the grinding cylinder is extended, pushing the guide plate to slide in the guide cylinder, which drives the rotating shaft to move in the grinding cylinder. The plug at the end of the rotating shaft is inserted into the feeding cylinder at the end of the grinding cylinder, thereby sealing the feeding cylinder on the grinding cylinder, effectively reducing the amount of ore dust overflowing from the grinding cylinder during crushing, thus protecting the processing environment. At the same time, the impact motor on the guide plate is started to drive the rotating shaft to rotate, which drives the impact balls connected by the chain on the rotating ring to rotate under the action of centrifugal force, thereby driving the impact balls to continuously impact the ore, accelerating the crushing efficiency of the ore in the grinding cylinder.

[0018] During use, the push rod on the support is held to push the support to slide towards the grinding cylinder on the slide bar seat, so that the open end of the conveying cylinder is inserted into the feeding cylinder of the grinding cylinder. The ore is added into the feeding cylinder of the conveying cylinder, and then the ore falls into the conveying cylinder. The conveying motor is started to drive the conveying screw to rotate. The screw pushes the ore into the feeding cylinder of the grinding cylinder. This conveying method reduces the spillage of ore dust. At the same time, the conveying screw squeezes the ore to pre-crush it, ensuring the ore conveying efficiency. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, an environmentally friendly mining mill includes a support component 1, a mill body 2, and a feeding component 3. The support component 1 includes a bottom hole frame 11, which is horizontally arranged, and a support frame 12 is vertically fixed on the bottom surface of the bottom hole frame 11. The support frame 12 is fixed to the mounting base by bolts. A support frame 13 is horizontally arranged on the top surface of the bottom hole frame 11, and the support frame 13 is vertically slidably mounted on the bottom hole frame 11. Two rotating plates 16 are symmetrically and vertically fixed on both sides of the top surface of the support frame 13. The mill body 2 includes a grinding cylinder 21, which is horizontally rotatably connected to the two rotating plates 16. Between the rotating plates 16, and on the inner circumferential surface of the grinding cylinder 21, a liner 22 is installed. Inside the grinding cylinder 21, an impact member 23 is provided. On one side of the support frame 13, a feeding member 3 is provided. The feeding member 3 is used to feed material into the grinding cylinder 21. In use, the feeding member 3 is pushed to connect and insert into the feed end of the ore mill body 2, and the ore and steel balls are introduced into the grinding cylinder 21 through the feeding member 3. Then, the impact member 23 is started to rotate in the grinding cylinder 21, and the ore is hammered in the grinding cylinder 21. The crushed ore is discharged from the grinding cylinder 21, thus completing the ore grinding process.

[0033] Please see Figure 3 , Figure 5 and Figure 7A feeding cylinder 211 is horizontally fixed at the center of one end face of the grinding cylinder 21, and a guide cylinder 213 is horizontally fixed at the center of the other end face of the grinding cylinder 21. The feeding cylinders 211 and guide cylinders 213 at both ends of the grinding cylinder 21 pass through two rotating plates 16, and the feeding cylinders 211 and guide cylinders 213 at both ends of the grinding cylinder 21 are rotatably connected to the two rotating plates 16 through bearings. Multiple fixing holes 214 are evenly opened on the outer circumference of the grinding cylinder 21, and a feeding screw cylinder 215 is vertically fixed on the outer circumference of the grinding cylinder 21. A screw plug 24 is threaded in the feeding screw cylinder 215. The feeding screw cylinder 215 is used to discharge the crushed ore in the later stage. The setting of the screw plug 24 is to prevent the ore from being discharged from the feeding screw cylinder 215. A driven gear ring 212 is fixed on the outer circumference of the feeding cylinder 211. A drive motor 17 is horizontally fixed on the vertical end face of the rotating plate 16 on the side of the support frame 13 near the feeding cylinder 211. A drive gear 18 is fixed at the output end of the drive motor 17, and the drive gear 18 meshes with the driven gear ring 212. When in use, the drive motor 17 is started to drive the drive gear 18 to rotate, which meshes and drives the grinding cylinder 21 to rotate on the rotating plate 16, causing the ore and steel balls to move in a circular motion to crush the ore.

[0034] Please see Figure 5 and Figure 6 Multiple guide posts 221 are fixed on the outer circumference of the liner 22, and the multiple guide posts 221 are installed through the fixing hole 214 of the grinding cylinder 21. The end of the guide post 221 is fixed with a stud 222, and a nut 25 is installed on the stud 222. The guide post 221 on the liner 22 is inserted through into the fixing hole 214 of the grinding cylinder 21, and then the nut 25 is threaded on the stud 222 on the guide post 221, thereby locking and fixing the liner 22 on the inner wall of the grinding cylinder 21.

[0035] Please see Figure 5 and Figure 8The impact component 23 includes a guide plate 231, which is slidably mounted in the guide cylinder 213. A rotating shaft 232 is horizontally rotatably connected to the guide plate 231. The rotating shaft 232 is horizontally inserted into the interior of the grinding cylinder 21. Multiple rotating rings 233 are horizontally fixed on the outer circumference of the rotating shaft 232. Multiple chains 234 are evenly fixed on the outer circumference of the rotating rings 233, and an impact ball 235 is fixed at the other end of each chain 234. A stopper 2321 is fixed at the end of the rotating shaft 232 near the feeding cylinder 211. A bracket 238 is horizontally fixed on the outer end face of the grinding cylinder 21 where the guide cylinder 213 is mounted, and a hydraulic cylinder 239 is horizontally fixed on the bracket 238. A push frame 237 is horizontally fixed on the guide plate 231, and the push frame 237 is fixedly connected to the output end of the hydraulic cylinder 239. An impact electrode is horizontally fixed on the outer end face of the guide plate 231. The machine 236, with the output end of the impact motor 236 fixed to the end of the rotating shaft 232, is used when the ore is added to the grinding cylinder 21. The cylinder 239 on the support 238 at one end of the grinding cylinder 21 is extended, pushing the guide plate 231 to slide in the guide cylinder 213, which in turn drives the rotating shaft 232 to move in the grinding cylinder 21. The plug 2321 at the end of the rotating shaft 232 is inserted into the feeding cylinder 211 at the end of the grinding cylinder 21, thereby sealing the feeding cylinder 211 on the grinding cylinder 21. This effectively reduces the amount of ore dust overflowing from the grinding cylinder 21 during crushing, thus protecting the processing environment. At the same time, the impact motor 236 on the guide plate 231 is started to drive the rotating shaft 232 to rotate, which drives the impact ball 235 connected by the chain 234 on the rotating ring 233 to rotate under the action of centrifugal force, thereby driving the impact ball 235 to continuously impact the ore, accelerating the crushing efficiency of the ore in the grinding cylinder 21.

[0036] Please see Figure 3 and Figure 4 A column 14 is vertically fixed on the bottom surface of the support frame 13, and the column 14 is vertically slidably inserted into the through hole of the bottom hole frame 11. A spring damping shock absorber 15 is vertically fixed on the bottom surface of the support frame 13, and the bottom end of the spring damping shock absorber 15 is fixed on the top surface of the bottom hole frame 11. When the ore mill body 2 is crushed during use, the vibration generated causes the support frame 13 to slide vertically on the bottom hole plate 11. The vibration is absorbed by the spring damping shock absorber 15, thus maintaining the stability of the ore mill body 2 during crushing.

[0037] Please see Figure 9 and Figure 10The feeding component 3 includes a slide bar seat 31, which is horizontally arranged on the side of the support frame 13 near the feeding cylinder 211. One end of the slide bar seat 31 is fixed to the support frame 13. A support 32 is vertically arranged on the slide bar seat 31, and a slider 33 is fixed on the bottom surface of the support 32. The slider 33 is horizontally slidably mounted on the slide bar seat 31. A push rod 34 is vertically fixed on the top surface of the support 32, and a conveying cylinder 35 is horizontally fixed through the top of the support 32. The end of the conveying cylinder 35 near the feeding cylinder 211 is open, and a guide cylinder 351 is vertically fixed through the top of the outer circumference of the conveying cylinder 35 on the side away from the feeding cylinder 211. A conveying screw 353 is horizontally arranged inside the conveying cylinder 35, and the end of the conveying screw 353 rotates. The conveyor is dynamically connected to the end face of the conveyor cylinder 35. The end of the conveyor cylinder 35 is horizontally fixed with a conveyor motor 352, and the output end of the conveyor motor 352 is fixed to the end of the conveyor screw 353. During use, the push rod 34 on the support 32 is held by hand to push the support 32 to slide on the slide rod seat 31 toward the grinding cylinder 21, so that the open end of the conveyor cylinder 35 is inserted into the feeding cylinder 211 of the grinding cylinder 21, and the ore is added into the feeding cylinder 351 of the conveyor cylinder 35. Then the ore falls into the conveyor cylinder 35. The conveyor motor 352 is started to drive the conveyor screw 353 to rotate, and the screw pushes the ore into the feeding cylinder 211 of the grinding cylinder 21. This conveying method reduces the spillage of ore dust. At the same time, the conveyor screw 353 squeezes the ore to pre-crush it, ensuring the ore conveying efficiency.

[0038] Working principle: During use, the push rod 34 on the support 32 is held to push the support 32 to slide towards the grinding cylinder 21 on the slide rod seat 31, so that the open end of the conveying cylinder 35 is inserted into the feeding cylinder 211 of the grinding cylinder 21, and the ore is added into the feeding cylinder 351 of the conveying cylinder 35. Then the ore falls into the conveying cylinder 35. The conveying motor 352 is started to drive the conveying screw 353 to rotate, and the screw pushes the ore into the feeding cylinder 211 of the grinding cylinder 21. After feeding is completed, the open end of the conveying cylinder 35 is pulled out of the feeding cylinder 211 of the grinding cylinder 21. Then the hydraulic cylinder 239 on the bracket 238 at one end of the grinding cylinder 21 is started to extend, pushing the guide plate 231 to slide in the guide cylinder 213, driving the rotating shaft. 232 moves within the grinding cylinder 21. The plug 2321 at the end of the rotating shaft 232 is inserted into the feeding cylinder 211 at the end of the grinding cylinder 21. Simultaneously, the impact motor 236 on the guide plate 231 is activated, driving the rotating shaft 232 to rotate. This causes the impact ball 235 connected to the rotating ring 233 via the chain 234 to rotate under centrifugal force, thereby causing the impact ball 235 to continuously impact the ore. The start-up drive motor 17 is activated, driving the drive gear 18 to rotate. This meshes and drives the grinding cylinder 21 to rotate on the rotating plate 16. After crushing, the feeding screw 215 on the grinding cylinder 21 is rotated downwards, the screw plug 24 is opened, and water is added to the grinding cylinder 21, pushing the crushed ore out of the grinding cylinder 21.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
