[0023] The effect achieved by the entire embodiment 1 is that, in the preparation process of limestone, the limestone with a size of ≤30 mm after being screened enters the tank body 206 through the feeding pipe 208 and the feeding hopper 207. The limestone is pre-treated after entering the tank body 206, and the larger particles in the screened limestone are crushed, so that the smaller granular limestone enters the grinding roller 7 position to complete uniform grinding. The motor 204 is started to drive the blade 211 to rotate through the connection of the rotating shaft 205. The rotation of the blade 211 can crush the limestone inside the tank body 206. After the crushing of the limestone inside the tank body 206 is completed, the hydraulic rod 202 is started to extend. After the hydraulic rod 202 is extended, it can drive the frame 2 03 moves downward, and the frame 203 drives the rotating shaft 205 to move downward.

[0026] Working principle: In the limestone preparation process, the limestone with a size of ≤30 mm is screened and enters the tank 206 through the feeding pipe 208 and the feeding hopper 207. The limestone is pre-processed after entering the tank 206, and the larger particles in the screened limestone are crushed, so that the smaller particles of limestone enter the grinding roller 7 to complete uniform grinding. The motor 204 is started and drives the blade 211 to rotate through the connection of the rotating shaft 205. The rotation of the blade 211 can After the limestone in the tank 206 is crushed, the hydraulic rod 202 is started to extend. After the hydraulic rod 202 is extended, the frame 203 can be driven to move downward, and the frame 203 drives the shaft 205 to move downward. The shaft 205 can drive the bottom plate 209 to move downward and away from the tank 206. At this time, the limestone in the tank 206 will fall for grinding. After the bottom plate 209 moves to the outer position of the air outlet hood 9, the air pump 10 is started to be connected to the air outlet hood 9 through the connecting pipe 8. The air outlet hood 9 blows air outward, and the limestone remaining on the surface of the bottom plate 209 can be blown out. The blown limestone will fall to the inclined plate 5, and the limestone will slide along the inclined plate 5 to the grinding roller 7. After the grinding roller 7 is driven to rotate by the external driving device outside the shell 1, the grinding process of the limestone is completed, which is convenient for the reuse of the limestone. The limestone can be crushed into uniform fine particles for grinding by the setting of pre-crushing the limestone inside the tank body 206. Fine particles can be completely fed between the powder rollers 7 for grinding, which improves the use effect of the grinding rollers 7 and further improves the uniformity of the device for recycling limestone grinding. While the rotating shaft 205 drives the bottom plate 209 to move downward, the top plate 210 on the upper side will follow the inner surface of the tank body 206 and move downward. The top plate 210 can scrape off the limestone powder attached to the inner wall of the tank body 206, avoiding the problem of limestone adhering to and accumulating on the inner wall of the tank body 206 and requiring frequent cleaning, thereby improving the convenience of device maintenance.
