Abstract

ABSTRACT The article focuses on the review of HPGR operation mainly from a technological point of view. A critical review of recent achievements in HPGR technology was carried out, and major research areas and interests were distinguished and characterized. The economic potentials of HPGR presses were analyzed from the scope of the energy consumption. The HPGR researches were grouped into the following subjects: construction and design of HPGR machines, HPGR feed characterizations, the process course and assessment of comminution operations in HPGR devices, modeling and optimization of HPGR operation, HPGR-based technological circuits, and impact of HPGR operation on effectiveness of beneficiation processes. Apart from that, quantitative and qualitative analyses of the publications registered in the Web of Science database were performed. The evaluation has been performed according to the most frequently published institutions, countries, and journals. The analysis of merit content was performed through a critical review of research areas and investigative topics characterized by keywords.
