The production process includes mixing and sintering, and through precise control of process parameters, the performance of sinter can be stabilized. In the steel industry, the quality of sinter is crucial to the entire production process, as it not only affects the smooth operation of the blast furnace, but also relates to the quality and cost of steel products. With the continuous progress of technology, the production process of sinter is constantly optimized and improved. Sinter needs to be mixed and stirred using a mixer during smelting.

[0003] In the prior art, such as the utility model with publication number CN211069848U, specifically a mixer for improving the uniformity of sinter granulation, including mixing box, the lower end of the mixing box is fixedly connected with a plurality of supporting legs, the lower end of the mixing box is provided with a discharge port, the upper end of the mixing box is provided with a feed hopper, the sidewall of the feed hopper is provided with a rotatable cover plate, the inside of the mixing box is provided with a mixing and stirring mechanism.
