stirred media regrinding

 · Analysis of media stress intensity for vertical stirred mills has been published (Jankovic, 2001). The stress events per unit volume are higher as stirred mills do not require the large empty zone required for tumbling action, therefore most of the mill volume in stirred mills can be occupied by media and ore, reducing the mill foot print.
