[0002] Pellet ore is a method of artificial bulk raw materials, which is a process of changing a powdery material into a product with physical properties and chemical composition that can meet the requirements of the next processing step. Pellet ore is a spherical artificial iron ore, with a diameter of about 10 - 16 mm, and its compressive strength is above 200 N. Pellet ore can be transported over long distances and stored for a long time, and it is an ideal raw material for blast furnace ironmaking. At the same time, it can also be used in the production of direct reduced iron. As an essential material in industrial production, the green pellets of pellet ore need to be crushed and screened before use.
