At present, coking coal resources of all countries in the world are scarce, the requirements on coke quality and stability are higher and higher due to large-scale blast furnaces, and strong caking coal in the coking coal resources is less and less, which is a contradiction especially prominent in China. According to the concrete condition of coal resources in China, various coking plants are dedicated to the research of coal blending schemes, namely, single coals with different brands are blended according to a certain proportion for coking so as to reasonably utilize the resources of coking coals in various regions and enlarge the reserve amount of the coking coals. The blended coal is adopted for coking, so that not only can high-quality coking coal be saved, but also the coking characteristics of various coals can be fully utilized, and the quality of metallurgical coke can be changed by making good use of the advantages and disadvantages.

At present, different single coals are mixed by a coal blending machine according to a certain proportion, namely, the flow of the single coals in each bunker is controlled by a weighing belt, and then the different single coals with proper proportion are conveyed to a crushing stirrer through a material mixing belt to be mixed, so that the preparation of the different single coals is realized.
