Jan 01 1988 0183 32 The surface mechanisms of loss of mass for coarse particles in wet autogenous grinding was investigated in batch experiments using tumbling mills of 075 and 175 m diameter Measurements of wear were carried out by following the mass of individual particl...

The fracture and autogenous comminution of quartzite

The autogenous mill uses tumbling to effect comminution but instead of special milling bodies being added pebbles of the material to be comminuted are used The autogenous comminution process utilises less than 0 1 per cent of the energy input The principal objective of the present work was to analyse autogenous milling behaviour in terms of...
