  • Scale‐up of power consumption in agitated ball mills

    Previous investigations have shown that the specific energy input is the overall parameter of influence on product size during communition in agitated ball mills from laboratory up to industrial scale. The specific energy input is the introduced energy related to the amount of comminuted material. This parameter can be used for mill scale‐up.
