[0029] Example 2, please refer to the attached Figure 1 -Attached Figure 8The utility model provides a technical solution: a fused magnesia pulverizing device, comprising a pulverizing device body 1, two supporting legs 2 are arranged at the bottom of the pulverizing device body 1, a pulverizing barrel 3 is connected between the two supporting legs 2 by bolts, a threaded line 32 is provided on the outer walls at both ends of the pulverizing barrel 3, a first protective cover 31 and a second protective cover 33 are respectively threadedly connected on the threaded lines 32 at both ends of the pulverizing barrel 3, a slide groove 301 is provided on the bottom surface of the pulverizing barrel 3, a filter plate 34 is slidably connected to the inner wall of the slide groove 301, a filter hole 341 is provided on the top surface of the filter plate 34, two connecting blocks 35 are fixedly connected to the outer wall of the filter plate 34, a clamping block 36 is rotatably connected between the two connecting blocks 35 on the filter plate 34, and the two connecting blocks 35 on the pulverizing barrel 3 are connected to the clamping block 36 by bolts.

[0031] In this embodiment, by providing a crushing device on the top of the crushing drum 3, large pieces of fused magnesia can be first crushed into small pieces by the crushing drum 51 and then crushed by the crushing device, which greatly improves the service life.
[0032] When in use, an impact hammer 44 is arranged inside the crushing cylinder 3, and a crushing cylinder 51 is arranged on the top of the crushing cylinder 3. A crushing device is arranged inside the crushing cylinder 51. When the crushing device body 1 needs to crush a larger volume of fused magnesia sand, the crushing blades 54 in the crushing cylinder 51 will first break the fused magnesia sand into smaller volumes, and then fall into the crushing cylinder 3. The impact hammer 44 can be used to crush it into a required size, thereby first breaking the large pieces of fused magnesia sand into small pieces, and then crushing the small pieces of fused magnesia sand, thereby greatly improving the working efficiency of the crushing process and increasing the service life of the equipment.
[0033] Working principle:
[0034] The first step is to first put the fused magnesia to be crushed into the feed hopper 55, and then the fused magnesia enters the crushing barrel 51. At this time, the second servo motor 53 is started, and the second servo motor 53 drives the crushing rod 531 to rotate, and the crushing rod 531 drives the crushing blade 54 to rotate, so that the crushing blade 54 can crush the large fused magnesia into small pieces, and then the fused magnesia enters the crushing barrel 3 through the circulation slot 5;
[0035] The second step is to start the first servo motor 4. The first servo motor 4 drives the rotating shaft 41 to rotate, and the rotating shaft 41 drives the fixed rod 43 to rotate, which can drive the impact hammer 44 outside the fixed rod 43 to rotate at a high speed, so that the impact hammer 44 continuously hits the fused magnesia sand that needs to be crushed. When the size required for crushing is reached, the fused magnesia sand can pass through the filter hole 341 of the filter plate 34 and fall into the collection place. If the size does not meet the crushing requirement, it will continue to be impacted and crushed in the crushing barrel 3 until the crushing requirement is met. In addition, the filter plate 34 and the outer wall of the crushing barrel 3 are fixedly connected to the connecting block 35, and the block 36 and the bolt cooperate to make the filter plate 34 and the crushing barrel 3 fixed for a second time, and the filter plate 34 can be quickly disassembled, so that when other tasks require crushing to different degrees, the filter plate 34 can be replaced and work can be done directly. At this point, the entire work process ends.
