Power-based modelling of single-stage AG and SAG mill circuitsdesign being calibrated to a two-stage circuit with AG or SAG mill product being passed to a pebble mill or ball mill stage for finished grinding. The two-stage circuit includes a “transfer size” of AG/SAG product that becomes the feed to the closed-circuit ball mill. This work is compares the existing El Soldado single-stage.single stage ball mill vs two stage,Analysis of the efficiency of the grinding process in closed circuit ball .Abstract. Ball mills for fine grinding cement clinker and additives are widely used around the world. To improve the efficiency of a ball grinding the ball mills are transferred in closed circuit with air-separators of various designs. In the article the analysis of existing grinding circuits on the basis of closed circuit ball mills made.
