MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

In functional performance analysis, you must differentiate between"coarse" and "fine" particles. To do so, you can select a specificparticle size as the target grind size for the ball mill circuit; for ex-ample, it is convenient to select the desired 80% passing size asthe target grind size. You can then use this target grind size to defineand distinguish between "coarse" and "fine" particles in any of thegiven circuit

The 30 mm ball diameter milling still performed better than the small ball diameters, but the performance for this ball size had decreased for the -2 mm +1.4 mm mono-size feed compared to the bigger -4 mm +2.8 mm mono-size feed. This therefore shows that should the material feed size continue to decrease, the smaller balls will
