seconds by ball mill. During this period of time more than50 of material left the fraction. It means the mentioned time is more than enough. In this respect 15 30 45 and 60 seconds were selected as grinding times. After this step a pulp with 60 solidof each fraction (equivalent to feed concentration of Miduk copper ball mills) was prepared. Due to the limitations of the Bond method for designing industrial grinding circuits simulation using phenomenological mathematical models has been increasingly used for projects destined to design and to improve the ball mill performance. The simulation method also allows assessing the integrated performance of comminution circuits.
