FLOFORM™ Iron Ore Pelletization FLOFORM™, an alternative Traditionally bentonite is used as binder, but it reintroduces deleterious elements such as silica and alumina. FLOFORM is typically dosed at % prior to balling, about 1/20th of Bentonite. Depending on the quality of iron ore, a dual binder system comprising both
during preheating, contrary to bentonite clays commonly used in pelletizing iron ore for blast furnaces. Due to the need to process increasing volumes of low grade iron, interest in organic binders has increased lately. Organic binders tend to produce good quality wet pellets which however often lack in compressive strengths after sintering.
Determination Of An Alternative Binder To Bentonite In ... Determination Of An Alternative Binder To Bentonite In Iron Ore Pelletization Prompt : Caesar is a famous mining equipment manufacturer wellknown both at home and abroad, major in producing stone crushing equipment, mineral separation equipment, limestone grinding equipment, etc.
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
