[0036] The guide plate 20 can pour the material in the conical bin 18 to the bottom of the two grinding rollers 19 respectively, which facilitates the rapid grinding of the material and improves production efficiency. When the ground material is discharged, it can be screened by the powder selector 9, and then the qualified material is discharged through the discharge port 10.

[0037] Combine Figure 2 and Figure 3 , a material storage box 7 is penetrated and fixedly connected at the center position of the top of the support frame 6, and a spherical material control box 15 is fixedly connected to the bottom of the material storage box 7. A material control disk 17 is provided on the inner wall of the spherical material control box 15, and through holes 16 are opened on the left and right sides of the top of the outer wall of the spherical material control box 15. The inner walls of the two through holes 16 are fixedly connected with spring guide pillars 27, and the surfaces of the two spring guide pillars 27 are sleeved with springs 26. The tops of the two spring guide pillars 27 are penetrated and slidably connected with a fixed plate 25, and the tops of the two fixed plates 25 are fixedly connected with a hammer 24. A blower 5 is fixedly connected to the left side of the top of the base 3, and the right end of the blower 5 is penetrated and fixedly connected to the transport pipe 4, and the right end of the transport pipe 4 is penetrated and fixedly connected to the outer shell 11. Cleaning components are provided on the front and back sides of the inner wall of the outer shell 11, and the transport pipe 4 and the spherical material control box 15 are penetrated and fixedly connected.

[0038] When the material falls onto the control plate 17, the control plate 17 rotates with the weight of the material. At the same time, the control plate 17 contacts the fixed plate 25, driving the fixed plate 25 to deflect, driving the hammer 24 above the fixed plate 25. Then, when the control plate 17 is separated from the fixed plate 25, the spring 26 rebounds, driving the hammer 24 to gently knock on the bottom of the storage box 7 to avoid material blockage.

[0039] Combine Figure 4 and Figure 5The cleaning assembly includes a connecting shaft 31, which is fixedly connected to the outer shell 11. The scraper boxes 22 are fixedly connected to the opposite sides of the two connecting shafts 31. Push plates 29 are provided on the inner walls of the two scraper boxes 22.

[0041] Working principle: When using the vertical mill device, first put the material into the storage box 7, and the control plate 17 set in the spherical control box 15 receives the material, and rotates to transport the material under the action of weight. At the same time, the control plate 17 will contact with the fixed plate 25 when unloading and rotate, driving the fixed plate 25, and the hammer 24 will also deviate accordingly. When the fixed plate 25 is out of contact with the control plate 17, the spring 26 rebounds and drives the hammer 24 to knock on the bottom of the storage box 7 to generate vibration, thereby avoiding the accumulation of material at the bottom of the storage box 7 and evenly sending the material into the transport pipe 4. At the same time, the blower 1 is turned on to transport the material, and the material is evenly sent into the vertical mill device, thereby achieving quantitative unloading and uniform transportation, avoiding The scraper 23 is in close contact with the grinding disc 21 during the rotation of the grinding disc 21, and the scraper 23 can scrape off the calcium carbonate powder adhering to the grinding disc 21 to prevent the material from adhering to the grinding disc 21. A counterweight 30 is fixedly connected to the top of the scraper 23, which can make the center of gravity of the scraper 23 always downward and keep it tightly connected to the grinding disc 21. The air inlet pipe 2 blows high-pressure gas into the scraper box 22 through the air pump 1. The high-pressure gas is ejected from the air outlet and acts on the grinding disc 21 to blow off the material that is relatively firmly adhered to the grinding disc 21, thereby preventing the material from adhering to the grinding disc after grinding, thereby improving the production efficiency of the vertical mill device.
