A Review of the Grinding Media in Ball Mills for Mineral …
10, 20 and 50 mm: The feed and desired product size distribution determine the optimal ball size. A three-ball mix was more effective for coarser feed whilst the two-ball mix of 10 mm and 20 mm was effective for a finer feed. 9.5, 25.4 and 41 mm: Specific rates of breakage are a function of feed size and ball diameter.

Jet mill working principle
For mills of 200-300 mm, the feed size can be a maximum of 1.5 mm. For smaller-size mills, the feed size is correspondingly finer. There are several factors, both operational and physical, which affect the fineness of the end product, such as feed rate, nozzle size, nozzle pressure, nozzle angle, airflow rate, feed particle size, chamber ...

Feed Size Distribution Feedforward Control for a Grinding Mill …
The efficiency of the mill to break ore is a function of both the feed size distribution and the relative hardness of the ore. When the feed size of a SAG mill becomes coarser, i.e. αr increases, the energy required to break the ore increases, i.e. φr and φf increases (Morrell et al., 1996; Morrell and Valery, 2001; Fang et al., 2018).
