Optimization of the high energy ball-milling: Modeling and ...

Fig. 5 shows the effect of the BPR on the t ig (energy or performance) in HEBM in three states: weigh loss of powder (BPR p), increasing ball diameter (BPR d) and increasing the number of balls (BPR n). As can be seen in this figure, an increase in the number of balls has a minimal impact on the milling energy during BPR increment.
