[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0026] A cement mill according to an embodiment of the present utility model will be described below in conjunction with the accompanying drawings.
[0027] like Figures 1 to 4As shown, one embodiment of the utility model is a cement mill, which may include: a main frame 1, a crushing roller 2, a screening component 3, and a crushing component 4, wherein the crushing roller 2, the screening component 3 and the crushing component 4 are respectively arranged and installed in the main frame 1.
[0028] It should be noted that the screening component 3 consists of a mesh 31 and a vibrator 32 , wherein the vibrator 32 is located on the mesh 31 , and the mesh 31 is inclined, and the first discharge port 12 is located at the end of the inclined end of the mesh 31 .
[0029] It is understandable that when cement falls from the crushing roller 2 into the screening assembly 3, fine cement will fall out of the screen 31, while cement that cannot fall out of the screen 31 will slide toward the inclined part of the screen 31 due to the vibration of the vibrator 32, and finally fall out from the first discharge port 12.
[0030] It should be further explained that a limit plate is provided below the screening component 3 , and the limit plate is connected to the second feed port 461 .
[0031] It can be further understood that the limiting plate below the screening assembly 3 prevents fine cement from falling out of the crushing assembly 4 , so that all the cement can fall into the second feed port 461 .
[0032] Specifically, the main frame 1 is provided with a first feed port 11 , a first discharge port 12 and a third discharge port 13 .
[0033] It should be noted that a limiting plate is provided below the first feed port 11 , and the second discharge port 462 is connected to the third discharge port 13 .
[0034] It can be understood that the limit plate arranged below the first feed port 11 is used to ensure that the cement entering from the first feed port 11 can fall into the crushing roller 2, and the second discharge port 462 arranged on the fixed barrel 46 is connected with the third discharge port 13 to allow the crushed cement to be discharged from the third discharge port 13.
[0035] Specifically, the crushing roller 2 is located directly below the first feed port 11 , the screening component 3 is located below the crushing roller 2 , one end of the screening component 3 is connected to the first discharge port 12 , and the crushing component 4 is located directly below the screening component 3 .
[0036] It can be understood that the cement is firstly crushed by the crushing roller 2, then falls into the screening component 3 for further screening, and finally falls into the crushing component 4 for crushing.
[0037] Specifically, the crushing assembly 4 is composed of: planetary gears 41, sun gears 42, ring gears 43, drive motors 44, crushing rollers 45 and fixed barrels 46, multiple planetary gears 41 and sun gears 42 are respectively arranged and installed in the ring gears 43, wherein the sun gears 42 are concentric with the ring gears 43, multiple planetary gears 41 are respectively arranged around the sun gears 42, and multiple planetary gears 41 are respectively meshed with the sun gears 42 and the ring gears 43, the fixed barrel 46 is arranged and installed on the ring gears 43, the crushing rollers 45 are respectively arranged and installed on the multiple planetary gears 41 and the sun gears 42, and the center of the sun gears 42 is connected to the output end of the drive motor 44.
[0038] It should be noted that the ring gear 43 is fixed and does not rotate along with the rotation of the plurality of planetary gears 41 , and a second feed port 461 and a second discharge port 462 are provided on the fixed barrel 46 and are located on both sides of the fixed barrel 46 .
[0039] It can be understood that the screened cement enters from the second feed port 461, and at this time the planetary gear 41 will revolve and rotate around the sun gear 42, thereby driving the rolling roller 45 connected to the planetary gear 41 to make the same movement, and the cement will be crushed by the rolling roller 45 and the fixed barrel 46, and finally fall out from the second discharge port 462.
[0040] In order to better explain the present invention, in one embodiment of the present invention, the specific implementation method is that the staff starts the driving end connected to the crushing roller 2, and then starts the driving motor 44 and the vibrator 32.
[0041] At this time, the staff pours cement from the first feed port 11, and the cement will fall into the crushing roller 2. The crushing roller 2 will crush the cement that is larger than the distance between the two rollers. The cement that has been initially crushed will fall into the screening component 3 for screening, and the cement that is smaller than the mesh 31 will fall from the mesh 31. The cement that cannot fall from the mesh 31 will fall out from the first discharge port 12 through the vibration of the vibrator 32.
[0042] The cement dropped from the screening component 3 will fall into the second feed port 461 through the limiting plate. At this time, the driving motor 44 will drive the sun gear 42 to rotate, and the sun gear 42 will drive the planetary gear 41 to rotate and revolve on the ring gear 43, and the rolling roller 45 connected to the planetary gear 41 and the sun gear 42 will make the same movement. Because there are gaps between the multiple rolling rollers 45 and between the fixed barrels 46, the cement falling into the gap will be squeezed and finally fall out of the second discharge port 462, slide to the third discharge port 13 connected to the second discharge port 462, and finally fall out of the third discharge port 13.
[0043] In summary, according to a cement mill of an embodiment of the utility model, the large pieces of mixture in the cement mixture can be crushed by the crushing roller 2, and dropped into the screening component 3 arranged below for screening, so as to further screen out the large pieces of mixture in the cement mixture, and prevent the large pieces of cement mixture from entering the crushing component 4 and causing damage to the crushing component 4.
[0044] The small mixture screened out will enter the crushing assembly 4, and the crushing roller 45 will be driven by the sun gear 42 and the planetary gear 41 for further crushing.
