[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1 to 7 As shown, it illustrates a roller mill for processing ultrafine mineral powder in one embodiment of the present invention, comprising: a base plate 1, a processing chamber 2 fixedly installed on the left side of the top of the base plate 1, a top cover 3 rotatably installed at the rear edge of the top of the processing chamber 2, a first handle 4 fixedly installed on the top of the top of the top cover 3, and a roller mill mechanism installed inside the processing chamber 2.

[0032] Grinding chamber 6 is fixedly installed on the top right side of the base plate 1. A connecting pipe 5 is fixedly installed at the bottom of the processing chamber 2. The other end of the connecting pipe 5 is connected to the grinding chamber 6. A grinding mechanism is installed inside the grinding chamber 6. A dust collection mechanism is installed at the top rear end of the base plate 1.

[0033] For example, such as Figure 7As shown, the grinding mechanism includes a central rotating bucket 13, a grinding plate 14, a mounting frame 15, a multi-stage cylinder 16, a multi-stage telescopic rod 17, a guide rod 18, a mounting groove 19, a vertical rod 20, a slider 21, and a spring 22. The central rotating bucket 13 is fixedly installed on the inner left wall of the grinding chamber 6. The grinding plate 14 is fixedly installed inside the grinding chamber 6 below the central rotating bucket 13. The multi-stage cylinder 16 is fixedly installed on the outer right wall of the grinding chamber 6. The multi-stage telescopic rod 17 is fixedly installed at the output end of the multi-stage cylinder 16, and the other end of the multi-stage telescopic rod 17 is fixedly mounted on... The mounting frame 15 is equipped with a guide rod 18 fixedly installed on the outer right side of the mounting frame 15. The guide rod 18 is slidably connected to the grinding chamber 6. The inner walls of the front and rear ends of the mounting frame 15 are vertically provided with mounting grooves 19. Sliding sliders 21 are slidably installed inside the two sets of mounting grooves 19. Vertical rods 20 are fixedly installed inside the two sets of mounting grooves 19. Each set of vertical rods 20 is slidably connected to the slider 21 at the corresponding position. Springs 22 are sleeved on the two sets of vertical rods 20. The bottom end of each set of springs 22 is fixedly connected to the top end of the slider 21 at the corresponding position.

[0034] For example, such as Figure 3 As shown, the grinding mechanism also includes a grinding roller 23, a fixed plate 24, a feeding hopper 25, and a telescopic hose 26. The grinding roller 23 is installed inside the mounting frame 15. Both ends of the grinding roller 23 are rotatably connected to the slider 21 at the corresponding positions. The fixed plate 24 is fixedly installed on the top left side of the mounting frame 15. The feeding hopper 25 is embedded and fixedly installed on the fixed plate 24. The telescopic hose 26 is fixedly installed at the bottom of the transfer hopper 13. The other end of the telescopic hose 26 is sealed and connected to the feeding hopper 25. A collection drawer 36 is slidably installed at the bottom right side of the grinding chamber 6. A second handle 37 is fixedly installed on the outer wall of the right side of the collection drawer 36.

[0035] For example, such as Figure 3 As shown, the roller mill mechanism includes a transmission chamber 7, a rotating shaft 8, a roller 9, a gear 10, a motor 11, and a guide plate 12. The transmission chamber 7 is fixedly installed on the outer right side of the processing chamber 2. Two sets of rotating shafts 8 are horizontally rotatably installed inside the processing chamber 2. Rollers 9 are fixedly installed on both sets of rotating shafts 8. The right side of both sets of rotating shafts 8 extends into the transmission chamber 7, and gears 10 are fixedly installed on both sets. The two sets of gears 10 are meshed and connected. The motor 11 is fixedly installed on the outer left side of the processing chamber 2. The output end of the motor 11 is fixedly connected to one of the sets of rotating shafts 8.

[0036] In some examples, when using this device, the operator first puts the material to be processed into the processing chamber 2, and then starts the motor 11 to drive the rotating shaft 8 to rotate. Because the gears 10 fixedly installed on both sets of rotating shafts 8 are meshed, they can drive the two sets of rollers 9 to crush the material put into the processing chamber 2. Then the crushed material enters the transfer hopper 13 inside the grinding chamber 6 through the connecting pipe 5. Then the material is put onto the grinding plate 14 through the telescopic hose 26. At the same time, the operator can start the multi-stage cylinder 16 to drive the set... The grinding roller 23 grinds the material placed on the grinding plate 14, thereby making the mineral particles smaller and ensuring the processing effect. Not only does it eliminate the need for manual removal of the material for further processing, but it also improves the processing efficiency to a certain extent. In addition, the telescopic hose 26 allows the material to be placed relatively evenly onto the grinding plate 14 as the grinding roller 23 moves, thus making the grinding efficiency even higher. Finally, in this device, the spring 22 allows the grinding roller 23 to adhere to the grinding plate 14 with a certain force, further ensuring the grinding effect on the material, thereby making the device more practical.

[0037] like Figure 2 As shown, this invention illustrates a roller mill for processing ultrafine mineral powder in another embodiment. The dust collection mechanism includes a support plate 27, a tee 28, a dust collection hood 29, a first connecting pipe 30, a dust collection fan 31, a second connecting pipe 32, a dust collection box 33, and a third connecting pipe 34. Dust collection hoods 29 are embedded and fixedly installed at the rear ends of both the processing chamber 2 and the grinding chamber 6. A support plate 27 is fixedly installed on the outer wall of the rear end of the grinding chamber 6. A tee 28 is fixedly installed at the top of the support plate 27. First connecting pipes 30 are fixedly installed at the rear ends of both sets of dust collection hoods 29. One end of each connecting pipe 30 is sealed to the other end of the tee 28. A vacuum cleaner 31 is fixedly installed at the top rear end of the base plate 1. The input end of the vacuum cleaner 31 is sealed to the second connecting pipe 32. The other end of the second connecting pipe 32 is sealed to the tee 28. A dust collection box 33 is provided at the top rear end of the base plate 1. The output end of the vacuum cleaner 31 is sealed to the third connecting pipe 34. The other end of the third connecting pipe 34 extends into the interior of the dust collection box 33. Protective nets 35 are fixedly installed inside both sets of dust collection hoods 29. Rubber pads 38 are fixedly installed at the four corners of the bottom of the base plate 1.

[0038] In some examples, when processing materials using this device, workers can activate the dust extraction fan 31 to suck up the dust generated during material processing through the dust collection hood 29. The dust is then transported to the dust collection box 33 through the first connecting pipe 30, the second connecting pipe 32, and the third connecting pipe 34. This not only prevents dust from flying in the workshop, reduces the dust concentration in the workshop, protects workers' health, and reduces the risk of occupational diseases, but also reduces the safety hazard of dust explosions. In addition, the protective net 35 in this device can block large particles of material that are accidentally splashed, thereby reducing the damage caused by large particles to the dust extraction fan and further improving the practicality of this device.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
