[0002] The layered structure of lepidolite powder can improve the toughness and crack resistance of polymer plastic materials. It can also make the material have a UV shielding effect through the polarization effect of the mica layer. As a mineral with a relatively high output, lepidolite also has many other excellent functions. For example, it can be used in traditional Chinese medicine to treat diseases such as headaches. It can be used in combination with objects such as aluminum hydroxide for flame retardants and lubricants. The beneficiation method of lepidolite ore mostly adopts positive flotation. Its working principle is that according to the easy floating characteristics of lepidolite, the flotation method is often used in the beneficiation process to select the mineral along with the foam, and then carry out normal drying treatment to finally select lithium concentrate.

[0003] During the mining of mines and mine shafts, the mined ore needs to be crushed, which requires the use of crushing equipment. There are many types of crushing equipment, such as jaw crushers, hammer crushers, impact crushers, roller crushers, etc. Jaw crusher is a mining machinery used to crush stones. Its principle is to drive the movable jaw group to swing through the driving unit, and the movable jaw group and the fixed jaw frame engage with each other to simulate the movement of the two jaws of animals, thereby crushing the material. However, the existing jaw crushers generally have the problem of one-sided extrusion during the crushing process, and the crushing efficiency is low.

The two groups of sleeves 308 are fixedly connected to the side wall of the bracket 207. A group of second pistons 310 are slidably sleeved inside the two groups of sleeves 308. The side walls of the two groups of second pistons 310 are respectively fixedly connected to a group of push rods 309 extending to the outside of the sleeve 308. One end of the two groups of push rods 309 located inside the sleeve 301 is respectively fixedly connected to a group of top plates 307. The ends of the two groups of top plates 307 are fixedly connected to the side wall of the rotating sleeve 204.

[0051] During the reciprocating sliding of the push frame 109, the push frame 109 drives the push rod 303 to slide back and forth inside the front cover 302, thereby pushing the first piston 304 to slide back and forth inside the sleeve 301. During the sliding of the first piston 304, the hydraulic oil inside the sleeve 301 is pushed and sucked. The hydraulic oil enters the sleeve 308 through the pipe 306, thereby pushing the second piston 310 to slide inside the sleeve 308.

[0052] Please refer to Figure 7 and Figure 8 The dust collection mechanism 4 includes an air outlet ring 401, which is fixedly sleeved on the top of the feed port 202. The inner wall of the air outlet ring 401 is slidably connected to multiple sets of fans 402. The bottom end of the air outlet ring 401 is provided with multiple sets of mounting grooves 403 corresponding to the fans 402. A set of filter cotton 404 is slidably sleeved inside the multiple sets of mounting grooves 403. The bottom ends of the multiple sets of filter cotton 404 are respectively fixedly connected to a set of cover plates 405. The inner wall of the cover plate 405 is slidably connected to two A group of limit pins 406 are extended to the outside of the cover plate 405, and two groups of grooves that match the limit pins 406 are opened inside the two groups of mounting grooves 403.

[0053] By pushing the cover plate 405, the cover plate 405 drives the filter cotton 404 to slide into the installation groove 403, so that the cover plate 405 drives the limit pin 406 to move. When the limit pin 406 contacts the installation groove 403, the limit pin 406 is pushed to slide inside the cover plate 405, thereby driving the rack 407 to move. The rack 407 drives the gear ring 409 to rotate, thereby driving the shaft 408 to rotate. The shaft 408 twists the torsion spring during the rotation process. When the cover plate 405 slides into the installation groove 403, the torsion spring pushes the shaft 408 to return to its original position, thereby causing the gear ring 409 to push the gear The rack 407 is reset, and the rack 407 pushes the limit pin 406 to reset, so that the rack 407 returns to the groove inside the installation groove 403. At this time, the limit pin 406 is blocked by the groove inside the installation groove 403, so that the cover plate 405 cannot slide out from the inside of the installation groove 403, and then the fan 402 pushes the air to pass through the filter cotton 404, and then under the push of the fan 402, it is ejected from the inside of the air outlet ring 401, thereby driving the surrounding air to flow into the crushing bin 201, so that dust gathers inside the entire crushing device, which is convenient for dust collection.

[0054] When using, the usage is as follows:

[0055] Step 1: Initial crushing

[0056] The raw ore is fed into the feed port 202 from the middle of the air outlet ring 401, and enters the crushing chamber 201. The impact hammer 211 rotates and strikes the raw ore up and down, thereby breaking the large pieces of raw ore into small pieces. These small pieces of ore fall from the crushing chamber 201 into the grinding chamber 101.

[0057] Step 2: Fine grinding

[0058] After entering the grinding chamber 101, the small pieces of ore slide between the multiple sets of grinding plates 106 and the sliding plates 104. The sliding plates 104 slide back and forth and drive the protrusions 105 to move. The protrusions 105 and the sliding plates 104 drive the small pieces of ore to rub against the outer walls of the grinding plates 106, so that the small pieces of ore are ground into powder by the grinding plates 106.

[0059] Step 3: Mineral powder collection

[0060] After the ore is ground into powder, the ore powder slides through the gap between the protrusion 105 and the grinding plate 106, and then slides down from the outlet on one side of the grinding chamber 101. A container for collecting the ore powder is placed under the outlet of the grinding chamber 101 so that the ore powder falls into the container.
