STRONG IRON ORE GREEN PELLETS. THEORY AND PRACTICE.

Agglomeration of iron ore is commonly done in large balling drums or discs using water together with an external binder as a binding media. The mechanical strength of wet green pellets controls the productivity of the balling circuits and influences the productivity of the subsequent firing process, as well. A critical parameter in balling is to find a suitable moisture level. Too wet green ...

Compression Testing of Green and Dry Iron Ore Pellets

01/01/2012· The green pellets produced in a pelletizer are too weak to withstand any type of severe handling; further processing at elevated temperatures is required to strengthen them before the pellets are shipped to a customer. The high-temperature processing protocol depends on the type of pellet. For RHF-based operations (self-reducing iron oxide/carbon composite pellets), the pellets are dried in ...

Binding mechanisms in wet iron ore green pellets with a ...

13/11/2006· Iron ore green pellets show both plastic and elastic behaviour and the difference in significance between these two mechanisms should be recognised. Plastic deformation occurs due to the load of above-lying green pellets in a static bed of green pellets and leads to decreased bed permeability in the drying zones. This is detrimental for both the fast-drying sequence and also for the oxidation ...
