The raw materials used in sintering and pelleting process have the characteristics of a variety of kinds, large amount of quantity, and quite different physical and chemical properties. Therefore, the uniform mixing of various raw materials is of great significance for the preparation of high-quality sinter and pellet. In this article, the action principle and strengthening effect of the intensive mixing technology on sintering, pelleting particle mixing, and the industrial application of the technology are elaborated. For the problems of blade wear, nuclear particle fragmentation and insufficient flux digestion in the production, suggestions for the addition of raw material screening equipment, pre-mixing equipment, and selective intensified mixing are proposed, which is expected to provide references for the sintering and pelleting industries to choose the intensive mixing-granulation technology according to the characteristics of different raw materials.
