Abstract: The article presents the results of investigations over the comminution processes in HPGR for copper ore. Crushing tests were run in a laboratory HPGR device for the material with a variable content of fine particles in following size fractions: from 0 to 6 mm, from 0.3 to 6 mm, from 1.5 to 6 mm and from 2.5 to 6 mm. The tests were performed for the material with moisture content of 0 and 2%. The obtained results show that comminution effectiveness for material with an increased moisture content decreased slightly. Also the removal of individual finest particle size fractions from feed had its effect in a lower comminution efficiency, and increasing the feed moisture caused deterioration of the energy and capacity indices for the process.
