Bonding Mechanism and Process Characteristics of Special Polymers Applied in Pelletizing Binders

Abstract
Pellet ore not only has excellent metallurgical and mechanical properties, but is also an important metallurgical raw material used to solve the problem of increasing depletion of global high-grade iron ore resources. Bentonite has long been widely used in pellet ore production, which is not only expensive but also causes serious metallurgical pollution. Organic binders can form stronger adhesion and cohesion with mineral particles inside the green pellets than capillary forces, which greatly improves the pelletizing rate and significantly increases the strength of green and dry pellets, and it becomes an indispensable alternative to bentonite because it volatilizes pyrolytically at high temperatures, leaving almost no inorganic contaminants inside the pellet ore. In order to let more pellet researchers fully understand the research status and pelletizing theory of organic binders, this review systematically summarizes seven common organic binders, and elaborates on their adhesion mechanism and process characteristics, so as to provide references for pellet researchers and readers to further prepare cost-effective pellet binders and improve advanced pelletizing technology.
