[0019] Furthermore, the grinding mechanism includes grinding rollers 14 rotatably installed on both sides of the box body 1, one end of the grinding rollers 14 is located outside the box body 1 and fixedly connected to the first gear 5, and a motor frame 13 is fixedly connected to the surface of the box body 1, and a first motor 8 is fixedly installed on the motor frame 13, and the output shaft of the first motor 8 is fixedly connected to one group of the first gears 5.

[0020] In this embodiment, by driving the first motor 8, the two groups of first gears 5 are driven to rotate in opposite directions, and the two groups of grinding rollers 14 rotate accordingly, so that the calcium carbonate base material put into the box body 1 can be ground, and the ground calcium carbonate falls on the filter plate 15. The calcium carbonate with the required particle size passes through the filter plate 15 and falls to the bottom of the box body 1, and the calcium carbonate with a particle size larger than the required particle size remains on the filter plate 15. After the initial grinding is completed, the sealing member at the discharge port 17 can be opened, and the calcium carbonate retained on the filter plate 15 can slide along the inclined surface of the filter plate 15 to the inside of the transfer bucket 2, and then the lifting mechanism is used to move the transfer bucket 2 to the top of the box body 1, and then the driving mechanism is used to drive the transfer bucket 2 to rotate, so that the transfer bucket 2 rotates downward toward the side of the box body 1, and the transfer bucket 2 can pour the calcium carbonate inside it into the inside of the box body 1 for secondary grinding.

[0021] Furthermore, the driving mechanism includes a second gear 11 fixedly mounted on one end of the rotating shaft 4, a tooth plate 20 meshing with the second gear 11 is provided on the surface of the rotating seat 3, a guide rod 21 is slidably connected to the surface of the tooth plate 20, the tooth plate 20 and the guide rod 21 are both vertically arranged, and the lower end of the guide rod 21 is fixedly connected to the rotating seat 3, a spring 22 is sleeved on the outer surface of the guide rod 21, one end of the spring 22 is fixedly connected to the tooth plate 20, and the other end of the spring 22 is fixedly connected to the rotating seat 3, and a top plate 10 is fixedly connected to the top of the box body 1, and the top plate 10 is located in the moving direction of the tooth plate 20, and a notch 9 is opened on the upper surface of the box body 1 close to the transfer bucket 2.

[0022] In this embodiment, when the lifting mechanism drives the transfer bucket 2 and the rotating seat 3 to move upward, the top plate 10 will block the tooth plate 20, and the lifting mechanism drives the transfer bucket 2 and the rotating seat 3 to continue to move upward.
