High Pressure Grinding Rolls ("HPGR") are applied in all stages of iron ore size reduction, from coarse ore grinding down to pellet feed preparation. In closed circuit operation, fine grinds can be achieved using HPGR in combination with dry or wet classification or a partial product recycle without classification.

grinding. The ore must be ground to a particle size sufficiently close to the grain size of the iron-bearing mineral to allow for a high degree of mineral liberation. Most of the taconite used today requires very fine grinding. Prior to grinding, the ore is dry-crushed in up to six stages, depending on the hardness of the ore.
