[0032] The working principle and use process of the utility model are as follows: during the processing and production of the active metallurgical lime production mixing equipment, the mixing equipment body 100 is stably placed at the processing and production position through the support frame 102 contacting the ground, and when the mixing equipment body 100 is stably placed and mixed, raw materials are injected into the interior of the mixing tank 101 through the feed port 104, and the main motor 105 drives the mixing agitator 106 to rotate to mix the raw materials, and the mixing agitator 106 mixes the raw materials and discharges them again through the discharge pipe 103, so as to facilitate the mixing of the active metallurgical lime during the processing and production through the mixing equipment body 100;

[0033] Then, when the mixing equipment main body 100 is processing and producing mixed active metallurgical lime, the feed port 104 enters the raw materials into the mixing tank 101, and the entered raw materials fall to the internal connection between the first rolling roller 1012 and the second rolling roller 1013, the auxiliary motor 1011 runs to drive the driving gear 1014 to rotate inside the groove 1016, the driving gear 1014 rotates to drive the first rolling roller 1012 to rotate, and at the same time, the driving gear 1014 rotates to engage with the outer surface of the driven gear 1015 to drive the second rolling roller 1013 to rotate, and the first rolling roller 1012 and the second rolling roller 1013 are rotated inward at the same time to grind the raw materials, so as to facilitate the grinding of the larger and harder particles mixed in the raw materials, and to facilitate the grinding and processing during feeding to fall again to the bottom end of the mixing tank 101 for rotation and mixing, thereby enhancing the quality of the mixed processing of active metallurgical lime, and improving the grinding and mixing effect and mixing quality of the mixing equipment main body 100 during the processing and production of active metallurgical lime;

[0034] Finally, after the mixing equipment body 100 has processed and mixed the active metallurgical lime, the internal active metallurgical lime has been discharged. At this time, when a small amount of active metallurgical lime remains on the inner surface of the mixing tank 101, the forward and reverse motor 107 drives the screw rod 1072 to rotate. The screw rod 1072 rotates to move the moving block 1073 on the outer surface of the screw rod 1072. When the moving block 1073 moves, it is in the internal stable control movement of the limited moving groove 1074, and drives the moving ring 1075 and the scraper 1076 to move. The scraper 1076 contacts the inner surface of the mixing tank 101 and moves to scrape off the remaining small amount of active metallurgical lime, which is convenient for cleaning the interior of the mixing tank 101 after processing and production.
