Pellet feed grinding by HPGR - ScienceDirect

2015-3-15  The iron ore pellet feed concentrate exits the beneficiation process as a pulp or high moisture content concentrate. A further size reduction therefore needs to be carried out wet to avoid drying costs, or dry if a low moisture content and local energy costs do allow for an economic drying process route. Traditionally, however, this regrinding of iron ore concentrate is achieved by wet ball

2006-11-13  Pelletization begins with the grinding and cleaning of the iron ore to meet the desired chemical quality. Additional grinding is sometimes needed to achieve the required balling properties in the pelletizing plant. The balling is done in large balling drums using water together with an external binder as a binding media. The wet green pellets are then dried and sintered in the pelletizing machine.

A Look at the Process of Pelletizing Iron Ore for Steel ...

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore. Separation techniques such as magnetic separation or froth flotation are then used to separate the gangue (unwanted) materials from the iron
