#### Optimization of continuous ball mills used for finishgrinding of ...

The labmill (∅ × m, ball charge filling ratio 10%, relative mill speed ) were fed with clinker meal with a Blaine surface area of 2700 cm 2 /g. The massspecific power consumption for the grinding to finenesses of 3000, 4000 and 5000 cm 2 /g were determined. The results are plotted in Fig. 7.
