Optimization of continuous ball mills used for finish

Therefore a huge test program was carried with a semi-industrial ball mill which was operated in closed circuit. The mass-specific surface area of the two feed materials (intermediate product) used were quite typical for industrial semi-finish grinding plants. The values were 2200 and 3000 cm 2 /g according to Blaine.
