Pressing iron ore concentrate in a pilot-scale HPGR.

2019-8-15  The present work studied the performance of a pilot-scale HPGR pressing an iron ore concentrate under a variety of conditions that are consistent with pre-grinding. As already observed by Van der Meer and Leite (2018) for iron ore pellet feed pressing and confirmed here, specific throughput tends to drop as the operating pressure is increased, as observed in industrial roller pressing operations.

Aspects of HPGR in Iron Ore Pellet Feed Preparation

As alternative to classification, a multi-pass system or closed circuit operation for HPGR can be established by product recycling, where a proportion of the HPGR discharge is recirculated (or the full throughput is recirculated is certain number of times) to achieve a finer final discharge product for subsequent pelletizing.

How to avoid errors in HPGR product characterization

2020-3-17  Both standard HPGR lab scale test or industry measurement deliver high amounts of samples. Those samples contain a certain moisture range. For iron ore concentrates the value of 0-12 % can be found on several worldwide installations with HPGR. Due to the high amount of sample of >100 kg the material has to be representably splitted. It is common to dry the material before analysis as well.

Aspects of HPGR in Iron Ore Pellet Feed Preparation

High Pressure Grinding is applied in iron ore pellet feed preparation to generate a specific surface area increase. The technology is applied for final grinding of fine concentrates or pre-grinding (ahead of conventional milling) of particles. The process assumes inter-particle breakage and inter-particle abrasion as a major factor in generation of fines which contribute to an effective
