Study of the effect of the mineral feed size distribution on a ball mill
In this paper, the effect of the feed size distribution was studied for a ball mill. Copper ore of 0.5% was tested using batch-grinding tests. Samples A monosize (-19+12.5), coarse (-19+6.3 mm), medium (-4.75+0.6 mm), and fine (+ 0.425-0.038 mm) particle size distributions were tested. Ore Dressing, Mineral Processing
