Mill throughput is a key driver for maintaining profitability at Mt Keith because of the low head grade (~0.5% Ni) and inherently low nickel recoveries due to the mineralogical makeup of the ore. The Nickel West Mt Keith Concentrator (NMK) has 2 parallel grinding modules consisting of one SAG Mill and one BALL Mill per module.
The performance of ball mill depends on number, size and density of balls, flow rate of material to be Minto Mine Mill Operations Plan. Twin 670 kW ball mills each 3.20 m diameter with 3.66 m EGL, in closed circuit with hydrocyclones, grinding to a product size of nominally 80% passing (P80) 250 μm.
of SAG mill performance through 1. Changes in liner/lifter design to maximize throughput while maintaining acceptable wear levels. 2. Changes in ball size to maximize particle breakage without producing exceptionally high impact forces. 3. Changes in grate and pan lifter designs to decrease internal mill recycle and increase throughput.
The mill charge volume has a great impact on grinding efficiency. For efficient grinding, autogenous (AG) and semiautogenous (SAG) mills need to be operated with the correct charge in order to maximize their throughput while avoiding overloading. The Outotec MillSense sensor system gives a precise indiion of the mill charge volume.
Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.

size while maximizing throughput, or when the circuit is SAG mill limited, achieve the ﬁnest grind size possible, thus increasing mineral liberation and recovery. GrindingExpert™ has been shown to typically increase throughput by 36% GrindingExpert™. More Tonnage. Better Grinding
Based on experience, mill liner designs have moved toward more open shell lifter volumetric capacity and a grate design to facilitate maximizing both pebblecrushing circuit utilization and SAG mill capacity. Mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
SAG mill itself and not on the test work program. Stated another way, money invested in a large SAG mill is an investment that can produce handsome returns if extra production is needed or simply to give the mine the option to mill the hardest ores at design throughput rates.
