The main variables for this test work were in-mill % solids and ball filling degree. Test work was carried out over a range of controlled conditions for the % solids and ball filling degree, both of which have been shown to have a significant influence on mill performance (Austin et al., 1984, Prasher, 1987, and Frances and Laguerie, 1998).
