than 70 Jlm. Smaller media gave bimodal size distribu­ tions with coarser particles remaining unbroken. With the larger media, the particles were broken effi­ ciently over the whole size range, giving a steeper size distribution. Overall, the authors suggested that stirred ball mills were best operated at high media
