2004114 However, at 6.1–21 and 38–879 μm ranges stirred mill product has 2.7% and 5.6% extra mass, respectively. If ball mill product is compared to the cement, the main difference occurs at 0.25–38 and 38–879 μm size ranges. The former is the amount for a ball mill product to reach the cement's fineness.
