The laboratory ball mill was lined with 12 pieces of trapezium lifters and filled with J b = 25% grinding balls. An iron ore was used to prepare the slurry at 50% solid concentration by mass. A series of tests were carried out to investigate the charge dynamics at different mill speeds and slurry filling.
