## Rationed Ball Mill Charging to Improve Grinding Efficiency

A rationed grinding ball test using 50% 76 mm plus 50% 51 mm martensitic alloy steel balls was initiated in January, 1980 The rationed charge was allowed to reach equilibrium in Unit 14 over a 100day period, and the test was then conducted through May, 1980 The eight grate discharge mills in the older building could not be chargedmakeup ball diameter of about 17 inches, that is, a mixture weighted toward 15 inches (3) An increase of 12% in capacity was predicted with the optimum make up ballOptimization of the makeup ball charge in a grinding millGrinding ball for initial assembly SAG mill refers to the grinding balls charged in the mill before the SAG mill reaches the design capacity(or normal production) Due to the instability of operating parameters,worker’s proficiency,feeding mineral and frequent impact between balls and liners,these circumstance maybe induce breakage ofGrinding Ball For Initial Assembly SAG MillGoldpro
