Effects Of Slurry Rheology On Industrial Grinding

Jul 01, 2002 The influence of viscosity on the Grinding Index is seen to be strongly dependent on slurry rheology. When grinding a dilatant slurry with a low or zero yield stress, increasing slurry viscosity leads to a higher GI (No. 6). But when the dilatant slurry exhibits a high yield stress, increasing viscosity reduces the GI (No. 7).
