  • EFFECT OF BALL SIZE DISTRIBUTION ON MILLING PARAMETERS

    A series of batch grinding tests were carried out using three loads of single size media, ie 306 mm, 388 mm, and 492 mm Then two ball mixtures were successively considered The equilibrium ball mixture was used to investigate the effect of ball size distribution on the terms of energy requirements and steel consumption related to grinding media and liners Spherical grinding media are predominantly used in final stages of ore grinding The spherical balls change shape through breakage and wear Though this is universal in milling, its contribution and effect on milling kinetics, load behaviour and mill powerEFFECTS OF GRINDING MEDIA SHAPES ON BALL MILL OVERVIEW ME Elecmetal has the capacity to manufacture premium quality forged grinding balls of all sizes ranging from 22 mm to 160 mm (7/8” to 6 ¼” approx) and in three product lines: ME Super SAG, for SAG mills; ME Ultra Grind, for ball mills; and ME Performa II for ball mills ME Elecmetal Grinding Media Plant located in Changshu, ChinaGrinding Media ME Elecmetal Global Presence and
