As one of leaders of determination of pelletizing characteristics of iron ore concentrate industry, SBM always seeks innovation & excellence.
The formation of raw iron ore pellets, also known as pelletizing, has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference, transport, and use. Both mechanical force and thermal processes are used to produce the correct pellet properties.

iron ore mixture are controlled for the grinding process in the pelletizing plant. The BI is generated by comminution of the iron ore concentrate, the process that dramatically impacts the cost of producing pellet feed (Schneider and Neumann, 2002). A preliminary study was done to check the grinding pro-cess and the limits of operational ...
