Major iron ore pelletproducing countries include China, Brazil, Sweden, the United States, Canada and the CIS. China is the world's largest pellet producer. Estimated annual output of around 120Mt for 2016 will be approximately 30% of global production.
"In addition, we anticipate that the iron ore pellet market will remain very tight in 2017, as Brazilian pellet producer Samarco's pelletizing plant remains idle and environmental regulations force iron ore producers to use more pelletized iron ore," SP observes.
Iron ore pellet sample supplied by a domestic pelletizing plant (China) was used as furnace burden in this work. The elemental composition of iron ore pellets was shown in Table 1. And the charged pellets were in the size range of –16 mm with average crushing strength of 2973 N/pellet.
Iron Ore pellets are superior to other substitutes due to their High Cold Crushing Strength resulting in minimal fines generation, while multiple handling resulting in increased savings. With uniform composition of material, size and Guaranteed Porosity, Swelling Index and negligible moisture due to dry process provides an added advantage for .
Pellets are obtained from the agglomeration of iron ore fines after addition of binders, generally hydrated lime or bentonite, to facilitate the formation and to increase the mechanical resistance of the so called "green pellets". Pellets have a spherical shape .
