[0021] The bottom of the cylinder 1 is fixedly connected to four symmetrical support columns, and the feed pipe 2 and the discharge pipe 5 are respectively located at the top and bottom of the cylinder 1. There are two feed pipes 2, and the feed pipes 2 are symmetrical with respect to the motor 6. A circular through hole is provided at the center of the guide ring 3, and conical grooves are provided at the top and bottom of the guide ring 3, and the conical grooves are connected to the circular through hole. The cross-sectional shape of the guide ring 3 is two symmetrical trapezoids, and the grinding chamber 1 31 and the grinding chamber 3 33 are respectively located on the conical groove surface of the guide ring 3, and the grinding chamber 2 32 is located on the inner wall of the circular through hole of the guide ring 3. The surfaces of the grinding chamber 1 31, the grinding chamber 2 32 and the grinding chamber 3 33 are all smooth. The grinding chamber 1 31 and the grinding chamber 3 33 are both inclined, and the caliber of the grinding chamber 1 31 decreases from the edge to the center, and the grinding chamber 3 33 decreases from the center to the edge. After the concrete and additives are put into the feed pipe 2, they are first drawn into the grinding chamber 1 31, and the concrete is ground for the first time by the rotation of the grinding block 1 8. The ground concrete then enters the grinding chamber 2 32, and is ground for the second time by the rotation of the eccentric grinding roller 9. At this time, the concrete with a small grinding diameter will slide into the grinding chamber 3 33, and is ground for the third time by the rotation of the grinding block 2 10. The fineness of the concrete is effectively improved by the three grindings. The support plate 11 is located between the grinding block 2 10 and the cross plate 13.

When the cross plate 13 rotates, the gear 15 will cause the stirring piece 16 to rotate and stir under the action of the gear ring 12, so as to stir and mix the concrete inside the cylinder 1.

[0022] Working principle: When in use, the staff adds slag concrete and antifreeze additives into the cylinder 1 from the feed pipe 2 respectively. The concrete and additives are drawn into the grinding chamber 31 from the surface of the guide ring 3. The driving motor 6 rotates the rotating shaft 7, so that the grinding block 8 rotates to grind the concrete drawn into the grinding chamber 31 for the first time. As the diameter of the grinding chamber 31 gradually decreases, the size of the ground particles is smaller. Then the concrete enters the circular through hole of the guide ring 3, and the concrete is rubbed by the rotation of the eccentric grinding roller 9 and the side of the grinding chamber 32. After the second grinding, the concrete slides into the grinding chamber three 33 due to gravity, and the concrete is ground for the third time by the rotation of the grinding block two 10. Since the diameter of the grinding chamber three 33 is gradually reduced, the grinding effect is effectively improved and the grinding fineness is improved. Then the concrete falls into the bottom of the cylinder 1, and the cross-turn plate 13 rotates under the drive of the rotating shaft one 7, and the cross-turn plate 13 drives the rotating shaft two 14 to rotate. Through the engagement of the gear 15 and the gear ring 12, the rotating shaft two 14 drives the stirring piece 16 to rotate while rotating, so that the concrete is stirred and mixed evenly.
