The Modelling of Autogenous Grinding - ScienceDirect
1989-9-1 · DIFFERENCES BETWEEN BALL AND AUTO- GENOUS MILLING The use of ball mill models have been base on the assumption of lumps and pebbles having a similar function as balls. In autogenous grinding Digre (1969) discusses three mechanisms of grind- ing namely abrasion, attrition and impact. Stanley (1972,1974,1975) identifies only two modes of grind- ing.
