Abstract:

The stone which is discharged from semi-autogenous mill is taken for grinding medium，to investigate the self-grinding abrasion law and product particle size distribution，stone grinding abrasion law and grinding mineral particle size distribution when the stone is   used as grinding medium .The results show that rocks since the wear of grinding fineness are below 0.125 mm under the condition of different grinding time，filling ratio and grinding concentration；When grinding stone as grinding medium，under the grinding conditions of filling rate is 50%，the concentration is about 60%，the grinding time is 19 min，the into grinding sample is 500 g ，it can obtain grinding with -45 microns content of 60%，the new born gamma -45 microns quantity of approximately 18%；Compared with a steel ball grinding mineral surface is covered by a large number of iron floc and severe corrosion，stone grinding particle surface with a small amount of floc when the stone as grinding medium，with no corrosion，the outline of the mineral formation is smooth and clean.Stone is a fine grinding process ideal grinding media.

Key words: semi-autogenous grinding stone, grinding medium, grinding, particle size distribution
