Pelletizing Wikipedia
Pelletizing is the process of compressing or molding a material into the shape of a pellet A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, and more The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking This chapter shows the status of the pelletizing process Iron Ore Pelletizing Process: An Overview IntechOpenThe iron ore pelletizing process consists of three main steps: 1 Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives anthracite, dolomite and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process; 2Iron Ore Pelletizing Process: An Overview
