  • GeolabsGlobal South Africa Comminution

    The Bond Rod Work Index Test determines the resistance of ore to grinding in a rod mill expressed as a work index kilo Watt hour per ton (kWh/t). The work index is then used to calculate the specific energy requirements for sizing rod mills or determining their throughput for a target grind. Sample Requirements 15kg -12.5mm
