    Keywords: fine wet grinding; ball mill; slurry rheology; breakage rates 1. Introduction It is generally observed that dry and wet grinding of materials in tumbling ball mills to very fine sizes can lead to the slowing down of the overall grinding process (Austin et al., 1984; Frances and Laguerie, 1998; Yekeler et al., 2001). This effect signifies that
