Jan 01, 2012 The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization .Mar 21, 2015 Iron ore pellets can be made from beneficiated or run of mine iron ore fines. Lean iron ores are normally upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized so that it can be used in an iron making process.
Apr 11, 2013 Bentonite is a predominant binder used in iron ore pelletization. However, the presence of a high content of silica and alumina in bentonite is considered undesirable for ironmaking operations. The objective of this study was to identify the alternatives of bentonite for iron ore pelletization. To achieve this goal, different types of organic and inorganic binders were utilized to produce iron.As the demand for iron ore rises, so does the need for higher capacities. Maybe it’s processing huge volumes of low-grade ore with minimal residual moisture. Or doubling your throughput with a high-capacity filter press. In either case, we have an innovative solution to make it both possible and profitable. Filter press Horizontal vacuum belt.
