In the equation, E 1 is the total power demand normalized by batch size (mol), and E 2 is the estimated power demand normalized by per mole of product (mol). As shown in Fig. 3., E 2 of the ballmilling process (K 2 CO 3 /KLBM, green ball) increased slightly from 10 to 38 kWh mol −1 (from 5 to 25 min). As the duration increased, extra energy was squandered with no yield increase.
