[0021] When grinding barite powder, select a suitable second filter 9 for installation. After the device is stably placed, start the device. The rotating shaft 7 on the bearing seat 4 rotates with the pre-cutter 8, and barite is added to the crushing box 2 through the feeding structure 5 on the top cover 3. The pre-cutter 8 performs preliminary crushing on the barite, and the crushed materials smaller than the holes of the first filter 6 fall into the grinding box 1. At the same time, the servo motor 12 starts and moves the movable block through the screw rod. The movable block moves with the grinding roller 11 inside the grinding box 1. At the same time, the grinding roller 11 rotates, thereby grinding the crushed materials falling into the grinding box 1, and discharging the powder smaller than the holes of the second filter 9. In this way, the grinding of the barite powder is achieved.

[0022] Through the above implementation scheme, the feeding structure 5 includes a feeding hopper 501, a strip hole 502, a blocking plate 503, a rubber pad 504, a rotating rod 505, a limiting block 506, a waist-shaped hole 507 and a stud 508. The strip hole 502 is provided on the feeding hopper 501, and the feeding hopper 501 is fixed on the top cover 3. The rubber pad 504 is installed on the blocking plate 503, and the blocking plate 503 is fixedly connected to the rotating rod 505, and the rotating rod 505 is located at both ends of the strip hole 502. The stud 508 is fixed on the feeding hopper 501, the waist-shaped hole 507 is provided on the limiting block 506, and the limiting block 506 is sleeved on the stud 508 through the waist-shaped hole 507. A nut is provided at the end of 508, and a limit block 506 contacts the rotating rod 505. A feeding structure 5 is provided on the top cover 3. By rotating and installing the blocking plate 503 in the feed hopper 501, a blocking effect can be achieved during the initial crushing of the barite raw material, preventing the crushed materials from splashing out of the feed hopper 501, thereby ensuring the safe addition of materials. A rubber pad 504 is provided on the blocking plate 503 to play an anti-collision role. The blocking plate 503 is suspended by the rotating rod 505 and does not affect the normal feeding of barite. A bar hole 502 is provided on the feed hopper 501, and the limiting block 506 is used to limit the rotating rod 505, which facilitates the installation and disassembly of the blocking plate 503.

[0023] When assembling the feeding structure 5, the blocking plate 503 with the rubber pad 504 is set into the feeding hopper 501 through the strip hole 502, the rotating rod 505 is hung at both ends of the strip hole 502, and then the limiting block 506 is set on the stud 508 through the waist hole 507, and the nut is installed on the stud 508 to complete the assembly of the feeding structure 5. When adding barite, the barite is placed in the feeding hopper 501, and the barite moves along the feeding hopper 501. When the barite After the barite contacts the rubber pad 504, it exerts a force on the blocking plate 503. The blocking plate 503 is forced to rotate and make way through the rotating rod 505, so that the barite can smoothly enter the crushing box 2 for preliminary crushing. After the barite passes through, under the action of gravity, the blocking plate 503 returns to a suspended state. The blocking plate 503 can block the fragments flying inside the crushing box 2, preventing the fragments from flying out of the feed hopper 501, thereby ensuring the normal subsequent feeding.

[0024] According to the above embodiment, the position limiting and fixing structure 10 includes a connecting plate 1001, a socket 1002, a cylinder 1003, a positioning seat 1004, a lifting rod 1005, a tapered rod 1006 and an insertion rod 1007. The socket 1002 is opened on the connecting plate 1001, and the connecting plate 1001 is fixed to the end of the second filter 9. The cylinder 1003 and the positioning seat 1004 are fixed on the grinding box 1. The lifting rod 1005 and the insertion rod 1007 are fixedly connected through the tapered rod 1006, and the lifting rod 1005 is connected to the cylinder. At the lower end of the telescopic shaft 1003, the second filter 9 is inserted into the grinding box 1, and the second filter 9 is fixed by the limiting fixing structure 10. After starting the cylinder 1003, the lifting rod 1005 rises with the tapered rod 1006 and the insertion rod 1007 to make way, and the second filter 9 can be quickly disassembled and replaced. After the cylinder 1003 descends with the lifting rod 1005 and other structures, the tapered rod 1006 can effectively ensure the stability of the connecting plate 1001, thereby ensuring the stability of the second filter 9 after installation.

[0025] When using the limiting fixing structure 10, in the initial state, the second filter screen 9 is used normally. At this time, the tapered rod 1006 is inserted into the insertion hole 1002, which plays a limiting and tight role on the connecting plate 1001 to ensure the stable use of the second filter screen 9. If the second filter screen 9 needs to be replaced, the cylinder 1003 is started, and the cylinder 1003 runs and drives the lifting rod 1005 to rise along the positioning seat 1004 until the tapered rod 1006 and the insertion rod 1007 are pulled out from the connecting plate 1001, and then the second filter screen 9 is pulled outward for disassembly, and then the second filter screen 9 with different hole sizes is replaced. After the second filter screen 9 is installed, the second filter screen 9 is inserted into the slot in the grinding box 1 until the second filter screen 9 can no longer move. At this time, the corresponding socket 1002 on the connecting plate 1001 is located below the insertion rod 1007. After starting the cylinder 1003, the lifting rod 1005 descends with the tapered rod 1006 and the insertion rod 1007. The insertion rod 1007 passes through the socket 1002, and the tapered rod 1006 is tightly inserted into the socket 1002, thereby fixing the connecting plate 1001. In this way, the second filter screen 9 is fixed, and then it can be used to continue grinding.
