Pelletizing is a method of artificial block raw materials. It is a process of converting powdered materials into physical properties and chemical composition that can meet the requirements of the next processing. During the pelletizing process, the material not only undergoes physical properties such as density, porosity, shape, size and mechanical strength due to rolling into balls and dense particles, but more importantly, chemical and physicochemical properties such as chemical composition, reducibility, expansion, high temperature reduction softening, low temperature reduction softening, and melting ratio occur, so that the metallurgical properties of the material are improved.
