Effect of ball load and size distribution on grinding . ensp 0183 ensp An industrial test work was performed to analyse the effect of applying a lower ball load and a finer ball size distribution in the second compartment of a KHD Humboldt Wedag 174 ball mill on grinding and classification performance of a hybrid high pressure grinding roll HPGR multi …
The operational controls are also reviewed for optimized mill operation. Every element of a closed circuit ball mill system is evaluated independently to assess its influence on the system. Figure 1 below is a typical example of inefficient grinding indicated by analysis of the longitudinal samples taken after a crash stop of the mill.
