[0023] In detail, the feed hopper 11 and the lower hopper 12 are communicated with the grinding chamber 3 and the storage chamber 4 respectively, and an electric valve is provided in the lower hopper 12 .

[0024] Furthermore, a first motor 9 is fixedly installed at the bottom of the grinding box 1, and the shaft end of the first motor 9 is located inside the grinding box 1 and is fixedly connected to a connecting rod 91, and the other end of the connecting rod 91 is located below the grinding element 5 and above the filter element 2 and is fixedly installed with a stirring rod 92.

[0025] It is worth mentioning that the first motor 9 drives the connecting rod 91 to drive the stirring rod 92 to rotate, so as to achieve the effect of stirring the barite powder. By stirring the barite powder, large pieces of barite can be transported by the elevator 8 for re-grinding, and small pieces of barite pass through the filter element 2 and come to the storage chamber 4 to wait for unloading;

[0026] Among them, the fineness of the barite powder is ensured to meet the requirements by re-grinding, and the barite powder that meets the requirements can be discharged under the action of the stirring rod 92 and the sieve plate 21. In this way, the space saved in the grinding box 1 can accommodate the next batch of barite, thereby avoiding the situation where the barite powder is ground uselessly multiple times, and can significantly improve the grinding efficiency of the barite powder.

[0027] In more detail, the filter element 2 includes a sieve plate 21, a protrusion 22 is provided at the bottom of the grinding box 1, and a through groove is penetrated through the end face of the protrusion 22.

The two ends of the spring 24 are respectively fixedly connected to the side of the sieve plate 21 and the protrusion 22, and the sieve plate 21 is slidably connected to the connecting rod 91.

[0028] It is worth mentioning that the sieve plate 21 can achieve a shaking effect by utilizing the function of the support rod 23 and the spring 24 and driven by the anti-blocking component 6, and the vibration generated by the shaking can prevent the barite powder from blocking the sieve holes of the sieve plate 21.

[0029] In general, the driving assembly 7 includes a second motor 71 fixedly installed on the side of the grinding box 1, the grinding member 5 is a pair of grinding rollers 51 rotatably connected to the inside of the grinding box 1, and the shaft ends of the pair of grinding rollers 51 are respectively fixedly installed with a first driving pulley 72 and a first driven pulley 73, a first transmission belt 74 is sleeved between the first driving pulley 72 and the first driven pulley 73, and the shaft end of the second motor 71 is fixedly connected to the shaft end of one of the grinding rollers 51.

[0030] The specific operation is that the shaft end of the second motor 71 drives one of the crushing rollers 51 to rotate, and the driven crushing roller 51 drives the first active pulley 72 to cooperate with the first transmission belt 74 to drive the first driven pulley 73 to rotate, so as to simultaneously drive a pair of crushing rollers 51 to rotate and crush and grind the barite.

[0031] Finally, the anti-blocking member 6 includes a cam 61, and the side of the grinding box 1 is rotatably connected to the cam 61 through a rotating shaft 62, and the cam 61 can contact the screen plate 21. A second driving pulley 75 is fixedly installed on the shaft end of the second motor 71, and a second driven pulley 76 is fixedly installed on the other end of the rotating shaft 62. A second transmission belt 77 is sleeved between the second driving pulley 75 and the second driven pulley 76.

[0032] It is worth mentioning that when the shaft end of the second motor 71 rotates, it also drives the second driving pulley 75 to rotate. The second driving pulley 75 cooperates with the second transmission belt 77 to drive the second driven pulley 76 to rotate. After the second driven pulley 76 is driven, it drives the cam 61 to rotate.

[0033] Among them, Figure 5 As shown, due to the action of the spring 24, the sieve plate 21 can shake in cooperation with the spring 24 under the drive of the cam 61, thereby preventing the sieve holes from being blocked by the barite powder.

[0034] Working mode: When working, barite is poured into the grinding box 1 from the feed hopper 11, and the shaft end of the second motor 71 drives one of the crushing rollers 51 to rotate, and the driven crushing roller 51 drives the first active pulley 72 to cooperate with the first transmission belt 74 to drive the first driven pulley 73 to rotate, so as to simultaneously drive a pair of crushing rollers 51 to rotate and crush and grind the barite;

[0035] Then, the first motor 9 drives the connecting rod 91 to drive the stirring rod 92 to stir the ground barite, and the large pieces of barite are transported by the elevator 8 through the stirring action for re-grinding, while the small pieces of barite enter the storage chamber 4 under the action of the screen plate 21 to prepare for unloading;

[0036] Finally, when the shaft end of the second motor 71 rotates, it will also drive the second driving pulley 75 to rotate. The second driving pulley 75 cooperates with the second transmission belt 77 to drive the second driven pulley 76 to rotate. After being driven, the second driven pulley 76 drives the cam 61 to intermittently squeeze the screen plate 21. The screen plate 21 uses the vibration generated by the shaking to prevent the screen holes from being blocked.
