Then the air will flow from the outside to the inside of the second grinding disc 405 along the second straight groove 412 and enter the third communication groove 410. Finally, the air will flow from the outside to the inside of the third grinding disc 406 along the third straight groove 413. When the air discharged into the inside of the third grinding disc 406 flows downward under the guidance of the flow guide cover 407 and flows through the grinding channel between the first grinding disc 404, the second grinding disc 405, the third grinding disc 406 and the stator grinding disc 18, it can absorb part of the heat generated during grinding and be discharged, thereby reducing the heat of the grinding surface and reducing the thermal fatigue of the metal material, further improving the service life of the equipment. At the same time, the air introduced from the outside into the equipment will carry the raw material particles with a particle size smaller than the size of the grinding channel outward when it passes through the grinding channel, so that it accelerates into the next grinding channel for grinding, thereby improving the grinding efficiency and having good anti-clogging effect. After grinding is completed, the air entering cannot be discharged upward after the flip cover 14 is closed, so as to restrict the air flow direction. At this time, the air entering amount is increased by the air pump 2 to play a role in flushing the surface of the first grinding disc 404, the second grinding disc 405, the third grinding disc 406 and the stator grinding disc 18, thereby achieving the cleaning effect.

[0051] The slag ground through the grinding channel will be blocked by the material control assembly 5 when it falls into the discharge hopper 15 and rolls to the lower outlet. At this time, the motor 504 is started to drive the rotating shaft 501 to rotate. The baffle 502 on the surface of the rotating shaft 501 will intermittently release the outlet of the discharge hopper 15, and the brush head 503 will be bent when it is squeezed and will rebound when it enters the discharge hopper 15, thereby having the effect of assisting the slag. This design is simple and has the effect of controlling the discharge speed of the slag, thereby avoiding excessive discharge of the slag and causing dust pollution, and improving the use effect of the equipment.

Any modification, equivalent replacement, improvement, etc. made within the scope of the present application should be included in the protection scope of the present application.

8. The method for using the synthetic dead-burned magnesia production device according to claim 7, characterized in that: The following steps are involved: Step 1: crush the ore for producing magnesia bricks into slag, start the motor (301), and then put the slag raw material into the lower hopper (13). Under the action of gravity, the raw material passes through the circular channel between the first bracket (306) and the first connecting block (401) and falls on the stator grinding disc (18). Then, it slides downward to the grinding channel between the third grinding disc (406) and the stator grinding disc (18). After the second grinding disc (405) rotates, the shear force generated by the stator grinding disc (18) will grind the medium-sized raw material into small-sized particles. Step 2: The large gear (304), the middle gear (303) and the small gear (302) are driven by the motor (301) at the same speed.

At this time, the gas in the annular air inlet shell (22) will enter the first connecting groove (408) through the gap between the discharge hopper (15) and the connecting shell (17). The air pump (2) increases the amount of air entering, thereby flushing the dust remaining on the surfaces of the first grinding disc (404), the second grinding disc (405), the third grinding disc (406) and the stator grinding disc (18). Step 4: The ground slag passes through the grinding channel and falls into the discharge hopper (15). When it rolls toward the lower outlet, it is blocked by the material control component (5). At this time, the motor (504) is started to drive the rotating shaft (501) to rotate. The surface of the rotating shaft (501) follows the rotating baffle (502) to intermittently release the outlet of the discharge hopper (15), and the brush head (503) is squeezed and bent. When it enters the discharge hopper (15) and rebounds, it has the effect of boosting the slag.
