  • Modelling Sag Milling Power And Specific Energy

    the mill power and the efciency of the mill operation If a sag mill has been designed with a conventional power or specic energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the expected power jul 29, 2018 clearances must be based on the final computed sag of the power line. take note that if we will not use the ruling span theory, the final sag would be different. for instance, if we apply directly the conductor state change equation to the 500 meters span the final tension would be 16,265 newtons with a sag of 23.35 meters.

    the value of is the sag of conductor at point as, at the support point and therefore, put the value of and in the equation we get ii)sag calculation when support are at unequal level: the unequal level suspension conductor is normal shown in As with most models, the power split between the sag and ball mills is evaluated and the transfer size necessary to balance the power draw between the two stages is estimated. If that transfer size is within the specified limits, then the calculation proceeds to calculate the sag
