Further, the ratio between mill airflow rate and separator speed influences the particle size distribution. A lower air flow rate will lead to a lower inclination of the particle size distribution curve. By these measures it has been possible to obtain particle size distributions for cement ground in OK mills similar to those for cement ground in ball mills (BM), as shown in Figure 6. Figure 6

Ball diameter here is in the range 60–80 mm. In a two-chamber mill, the media in the second chamber are typically in the range 15–40 mm, although media down to 5 mm are sometimes encountered. As a general rule, the size of media has to match the size of material being ground: large media can't produce the ultra-fine particles required in the finished cement, but small media can't break
