The effect of slurry rheology on fine grinding in a

2003-3-1  1.. IntroductionIt 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 ball–ball collision in the grinding region cannot transmit sufficient stress to fracture individual
