DETAILED DESCRIPTION
[0022] like Figures 1-2 As shown, the utility model is a production equipment for composite mineral admixtures for concrete, comprising a main tank 1, wherein the main tank 1 is connected with a crushing device 2 for crushing materials, and the crushing device 2 comprises: a first motor 21, a first stirring roller 22, a second motor 23, a second stirring roller 24 and a wedge block 25. The first motor 21 is located outside the main tank 1 and is fixedly connected to the main tank 1, and the output shaft of the first motor 21 passes through the main tank 1 and is connected to the first stirring roller 22, and the first motor 21 drives the first stirring roller 22 to rotate. The second motor 23 is located outside the main tank 1 and is fixedly connected to the main tank 1, and the output shaft of the second motor 23 passes through the main tank 1 and is connected to the second stirring roller 24, and the second motor 23 drives the second stirring roller 24 to rotate. The first stirring roller 22 and the second stirring roller 24 are arranged opposite to each other, so that the material is located in the gap to crush the material. A plurality of wedge blocks 25 are evenly arranged on the first stirring roller 22 and the second stirring roller 24, and the material is crushed by the wedge blocks 25. The main tank 1 is connected with a wedge-shaped groove 3 to facilitate the material to slide into the circular groove 4. The bottom of the wedge-shaped groove 3 is provided with a circular groove 4, and a grinding device 5 is provided at the bottom of the circular groove 4. After the material enters the circular groove 4, it falls into the grinding device 5. The lower part of the main tank 1 is connected with a storage tank 13 for collecting the ground material, and the storage tank 13 can be provided with an outlet 14 for the material to be discharged.
[0023] like Figures 1-2 As shown, the main tank 1 is rotatably connected with a third stirring roller 7 and a fourth stirring roller 8, and the third stirring roller 7 and the fourth stirring roller 8 are arranged oppositely, and the distance between the third stirring roller 7 and the fourth stirring roller 8 is smaller than the distance between the first stirring roller 22 and the second stirring roller 24. Thus, the material is further broken up. The first stirring roller 22 is connected with a first turntable 11, and the third stirring roller 7 is connected with a second turntable 6. A belt 10 is connected between the second turntable 6 and the first turntable 11, and the third stirring roller 7 is driven to rotate through the first turntable 11. The second stirring roller 24 is connected with a third turntable 9, and the fourth stirring roller 8 is connected with a fourth turntable 12. A belt 10 is connected between the third turntable 9 and the fourth turntable 12, and the fourth stirring roller 8 is driven to rotate through the third turntable 9.
[0024] like Figures 1 to 5 As shown, the grinding device 5 includes: a first grinding block 51, a second grinding block 52, a third motor 56, a gear 55, a gear ring 53 and a third grinding block 54. The first grinding block 51 is conical and hollow inside. The first grinding block 51 is connected to the lower part of the circular groove 4, so that the material falls from the circular groove 4 into the first grinding block 51, and then falls from the first grinding block 51 into between the first grinding block 51 and the second grinding block 52. The third grinding block 54 is located at the bottom of the storage tank 13. The third grinding block 54 is conical and inverted. The second grinding block 52 is located between the third grinding block 54 and the first grinding block 51. The upper and lower surfaces of the second grinding block 52 are concave to fit the first grinding block 51 and the third grinding block 54. Holes are opened in the middle of the second grinding block 52 and the first grinding block 51 to facilitate the passage of materials. The gear ring 53 is located outside the second grinding block 52, the third motor 56 is fixedly connected to the bottom of the wedge-shaped groove 3, the output shaft of the third motor 56 is fixedly connected to the gear 55, and the gear 55 is meshed with the gear ring 53. The third motor 56 drives the gear ring 53 and the second grinding block 52 to rotate.
[0025] The working process of the above scheme is as follows: the first motor 21 and the second motor 23 are started, and the first stirring roller 22 and the second stirring roller 24 rotate to initially break the material. The first stirring roller 22 drives the first turntable 11 to rotate, and the first turntable 11 drives the second turntable 6 and the third stirring roller 7 to rotate through the belt 10. The second stirring roller 24 drives the third turntable 9 to rotate, and the third turntable 9 drives the fourth turntable 12 and the fourth stirring roller 8 to rotate through the belt 10. Thus, the material is further broken. When the material falls into the wedge-shaped groove 3, the material slides into the circular groove 4. At this time, the third motor 56 is started to drive the gear 55 to rotate, and the gear 55 drives the gear ring 53 and the second grinding block 52 to rotate, so that the material is finely ground. The material falls from the circular groove 4 into the first grinding block 51, and then falls from the first grinding block 51 into the space between the first grinding block 51 and the second grinding block 52. After grinding, it falls into the space between the second grinding block 52 and the third grinding block 54 for grinding, and then falls into the storage tank 13 and is discharged from the outlet 14.
[0026] The above scheme has the following beneficial effects: the material is crushed by the crushing device 2 to prevent the material blocks from being too large; the material is further crushed by the third stirring roller 7 and the fourth stirring roller 8 to make the material smaller and easier to grind by the grinding device 5; the material is ground finely by the grinding device 5; the second grinding block 52 rotates so that the material and the first grinding block 51 are ground and then fall between the second grinding block 52 and the third grinding block 54 to achieve a double grinding effect.
[0027] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
