Grinding Medium an overview ScienceDirect Topics

The grinding medium employed contains: 0.35 M sorbitol, 25 mM Hepes-KOH When examining the shape of the size distributions at different grind times (Figure 10.9), it is obvious that very little grinding occurs above a size of approximately 800 μm and hence very little change in the P 80 is observed. However, the finer fractions are being
