Modelling the performance of industrial ball mills using ...
Recently a ball mill modelling scheme to describe the performance of indus- trial ball mills using an ore-specific breakage distribution function in a multi- segment ball mill was developed (Narayanan, 1985; Narayanan and Whiten, 1985a). The ore-specific breakage distribution function is determined from single particle breakage tests.
