Achievement of High Energy Efficiency in Grinding Mills

2018-2-20 · SAG Mill Ball Charge The SAG mill was simulated to require a 10-12% ball charge with a top size of 125mm. During the commissioning phase no balls were required to be added to the SAG mill to achieve the target throughput of 575tph. This allows for great flexibility in the future and significant security for the future.

High Energy Ball Mills for Nano-Scale Grinding

2011-5-11 · There are basically two methods of producing nano-scale particles: the “Bottom-Up” technique involves synthesizing the particles from atoms and molecules. With the “Top-Down” method the particles are reduced to nanometer size by grinding. Suitable tools for this method are planetary ball mills, such as Retsch’s new PM-series grinders, which provide the necessary
