A first servo motor 3 is fixedly mounted on the rear surface of the processing frame 2. A scraper 7 is fixedly mounted on the inner wall of the processing frame 2. A through hole 10 is opened on the upper surface of the crushing kettle 1.
[0023] The first crushing structure, the second crushing structure and the third crushing structure have the same structure and include a driving gear 4, the outer surface of which is meshed with a driven gear 5, a crushing roller 6 is movably installed on the inner wall of the processing frame 2, a rotating column 8 is fixedly installed on the front surface of the driving gear 4, and a belt 9 is sleeved on the outer surface of the rotating column 8.
[0024] Specifically: During the use of the present invention, when heavy calcium carbonate needs to be processed, when the heavy calcium carbonate is placed inside the processing frame 2, the first servo motor 3 is started, and the first servo motor 3 starts to drive the driving gear 4 to rotate. The driving gear 4 rotates, thereby driving the crushing roller 6 to rotate. When the driving gear 4 rotates, it also drives the rotating column 8 to rotate. The rotating column 8 rotates and drives the other two driving gears 4 to rotate through the belt 9, thereby driving the crushing rollers 6 inside the first crushing structure, the second crushing structure, and the third crushing structure to rotate. When the first crushing structure, the second crushing structure, and the third crushing structure are all in operation, the heavy calcium carbonate first passes through the first crushing structure to crush the larger agglomerated heavy calcium carbonate, then passes through the second crushing structure to crush the medium-sized heavy calcium carbonate, and finally passes through the third crushing structure to crush the smaller heavy calcium carbonate. When it is in operation, the scraper 7 will be in real time attached to the surface of the crushing roller 6, thereby cleaning the heavy calcium carbonate adhering to the surface of the crushing roller 6, and the cleaned heavy calcium carbonate falls directly.
[0025] In this embodiment, a controller 14 is fixedly mounted on the front surface of the crushing kettle 1 , a support column 15 is fixedly mounted on the lower surface of the crushing kettle 1 , and a discharge port 16 is provided on the lower surface of the crushing kettle 1 .
[0026] Specifically: the treated heavy calcium carbonate is discharged through the discharge port 16 .
[0027] In this embodiment, the output end of the first servo motor 3 is fixedly connected to the front surface of the driving gear 4 of the first crushing structure, the lower surface of the scraper 7 is in contact with the outer surface of the crushing roller 6, the front and rear surfaces of the driving gear 4 and the driven gear 5 are movably connected to the interior of the processing frame 2, and the spacing between the crushing rollers 6 in the first crushing structure, the second crushing structure, and the third crushing structure are all different and gradually decrease from top to bottom.
[0028] Specifically: the first crushing structure crushes the larger agglomerated heavy calcium carbonate, then passes through the second crushing structure to crush the medium-sized heavy calcium carbonate, and finally passes through the third crushing structure to crush the smaller heavy calcium carbonate.
[0029] In this embodiment, four support columns 15 are provided.
[0030] Specifically: the four support columns 15 can provide stable support.
[0031] Working principle: The utility model can achieve the effect of crushing heavy calcium carbonate lumps of different sizes through the first crushing structure, the second crushing structure and the third crushing structure, and can achieve the effect of cleaning the surface of the crushing roller 6 through the scraper 7.

[0034] Specifically: when the crushed heavy calcium carbonate falls into the interior of the filter frame 11 through the through hole 10, the second servo motor 13 is started, thereby driving the stirring rod 12 to rotate. The stirring rod 12 rotates to break up the crushed heavy calcium carbonate. The broken heavy calcium carbonate falls into the interior of the crushing kettle 1 through the filter frame 11 and is discharged through the discharge port 16.
