[0045] The embodiment is specifically as follows: during operation, the refractory material is conveyed into the crushing box 3 by the screw conveyor 4, and the refractory material falls on the partition plate in the crushing box 3, and then the second motor 311 on the upper cover 31 is started, and the third rotating shaft 33 is driven by the second motor 311 to rotate, driving the crushing frame 331 to crush the refractory material on the partition plate 32 into particles.

During the circular motion, the gear 244 will rotate, thereby driving the second rotating shaft 22 to rotate.

[0049] The specific implementation method is as follows: when grinding, the cylinder 12 in the bottom box 1 is first started, and the grinding mechanism in the grinding box 2 is pushed upward by the cylinder 12, and the top cover 23 on the grinding box 2 moves upward and opens, and the refractory material in the crushing box 3 will enter the grinding box 2.

When the gear 244 makes a circular motion, the gear 244 will rotate, thereby driving the second rotating shaft 22 to rotate, and the refractory material is ground by the grinding blades 221 on the first rotating shaft 21 and the second rotating shaft 22. When the second rotating shaft 22 makes a circular motion, it will also rotate itself, thereby driving the grinding blade 221 to move in different ways, increasing the movement range of the grinding blade 221, thereby improving the grinding effect and efficiency of the device on the refractory material, and when the crushed refractory material is ground, the wear on the grinding blade 221 can be reduced, thereby increasing the service life of the grinding blade 221.

[0050] according to Figure 10-11 The shown device is a fine grinding device for refractory material production, wherein the bottom box 1 is provided with material receiving boxes 13 on both sides thereof, and the ground refractory materials are collected by the material receiving boxes 13.

The two sides of the protective frame 11 are inclined plates, and the bottom end of the inclined plate is in contact with the top of the clamping plate 15. The grinding mechanism is driven downward by the cylinder 12, and the bottom cover 31 moves downward, thereby opening the bottom end of the grinding box 2. The refractory material in the grinding box 2 will fall and enter the material receiving box 13 along the inclined plates on both sides of the protective frame 11.

[0052] Furthermore, rollers 131 are movably installed at the four corners of the bottom end of the material receiving box 13, and a slide rail compatible with the rollers 131 is fixedly installed at the inner bottom end of the bottom box 1. The material receiving box 13 is slidably connected to the bottom box 1 through the rollers 131.

During the rotation process, the turntable 14 drives the torsion spring 17 to be squeezed;

[0054] The specific implementation method is as follows: after the refractory material is ground, the grinding mechanism is driven downward by the cylinder 12, and the bottom cover 31 is moved downward, thereby opening the bottom end of the grinding box 2, and the refractory material in the grinding box 2 will fall and enter the material receiving box 13 along the inclined plates on both sides of the protective frame 11 to collect the refractory material. During the collection process, the turntable 241 is in a rotating state to prevent the remaining refractory material from being stranded on the turntable 241. After the collection is completed, the bottom cover is reset by the cylinder 12, and the cycle is repeated. The refractory material is transported, crushed, ground and taken out in turn, reducing the use of human resources. When the material receiving box 13 needs to be taken out, it is first moved along the inclined plates on both sides of the protective frame 11 to collect the refractory material. The turntable 14 is rotated along the clamping ring 16, and the clamping plate 15 is driven to rotate through the first connecting shaft 142, so that the clamping plate 15 is disengaged from the clamping slot on the bottom box 1, and the limit of the material receiving box 13 is released. Then the material receiving box 13 is pulled out along the slide rail, and the material receiving box 13 is pushed by the roller 131, which is more convenient. The turntable 14 will drive the torsion spring 17 to be squeezed during the rotation process. After the refractory material in the material receiving box 13 is processed, the material receiving box 13 is pushed back into the bottom box 1, and then the turntable 14 is released. The torsion spring 17 will drive the turntable 14 to rotate, reset the clamping plate 15, and insert the clamping plate 15 into the clamping slot of the bottom box 1 to limit the material receiving box 13.

After the refractory material is cleaned, the second electromagnet 352 at the other end is started to drive the collar 34 to rotate and reset, thereby driving the baffle 341 to close the through slot 321 for continued use. Then, the refractory material remaining in the crushing box 3 can be introduced into the grinding box 2 for grinding;

[0057] Refer to the instruction manual Figure 8-9 When grinding, first start the cylinder 12 in the bottom box 1, and push the grinding mechanism in the grinding box 2 upward through the cylinder 12, and the top cover 23 on the grinding box 2 moves upward to open, and the refractory material in the crushing box 3 will enter the grinding box 2. After reaching a certain amount, the grinding mechanism is reset by the cylinder 12, driving the top cover 23 to close the top of the grinding box 2, and then start the first motor 242 inside the bottom cover 24, and grind the refractory material through the grinding blade 221 on the first rotating shaft 21 and the second rotating shaft 22. During the circular motion, the second rotating shaft 22 will also rotate, thereby driving the grinding blade 221 to move in different ways, increasing the motion range of the grinding blade 221, thereby improving the grinding effect and efficiency of the device for the refractory material, and when the crushed refractory material is ground, the wear of the grinding blade 221 can be reduced, thereby increasing the service life of the grinding blade 221;

[0058] Refer to the instruction manual Figure 10-11After the refractory material is ground, the grinding mechanism is driven downward by the cylinder 12, and the bottom cover 31 moves downward, thereby opening the bottom end of the grinding box 2, and the refractory material in the grinding box 2 will fall and enter the collecting box 13 along the inclined plates on both sides of the protective frame 11 to collect the refractory material. During the collection process, the turntable 241 is in a rotating state to prevent the remaining refractory material from being stranded on the turntable 241. After collection, the bottom cover is reset by the cylinder 12, and the cycle is repeated, and the refractory material is transported, crushed, ground and taken out in turn, reducing the use of manpower. When the collecting box 13 needs to be taken out, the turntable 14 is first rotated along the clamping ring 16, and the first connecting shaft 142 drives the card plate 15 to rotate, so that the card plate 15 disengages from the card slot on the bottom box 1, releasing the limit of the collecting box 13, and then the collecting box 13 is pulled out along the slide rail, and the collecting box 13 is pushed by the roller 131.
