2012-2-1 Conversion to SAG milling by adding 5% (v/v) balls resulted in an overall increase of 40% in the mill throughput, and a relative reduction of 3% in the product size. More stable plant operation was obtained in the SAG operating mode, as quantified by a reduction of 16% and 15% in the standard deviations of mill power draw and product size, respectively.

Abstract At the concentration plant of the Gol-E-Gohar Iron Ore Company (Iran) three 9 m × 2.05 m AG (autogenous) mills (fixed speed) are used in parallel in a dry operation. The performance of AG mills has been lower than the target value indicated by an increase in the product size (P 80 ; 80% passing size) from 450 μm (target) to 515 μm and low power draw (50% of nominal).

2019-7-1 An optimization is carried out to minimize the yearly cost of energy for the operation of the SAG mill. This cost includes the energy consumption cost in $/kWh and the capital cost for the PV-BESS infrastructure, prorated over the life of the battery system, accounting for the discount rate through an annuity factor (Pamparana et al. 2019a, b).The energy requirements are defined by the SAG ...

2020-6-23 Converting a mill from an overflow to a grate discharge arrangement leads to an increased power draw. This happens because the installation of the grate discharge arrangement enables the mill to run with a lower level of slurry due to it being no longer necessary for the slurry to build up inside the mill until it overflows from the mill discharge.
