In ball milling process, the BD of wheat straw increased continually with milling time, from 0.17 g/mL of CK to 0.44 g/mL of BM8.0 h (Fig. 2). In the beginning of ball milling process, wheat straw was crushed to small piece, decreasing the void space between particles, which resulted in the increase of BD.

The ball milling time (T b) was varied in a wide range (T b = 2–60 h). Hardened stainless steel vial with WC balls (5 mm in diameter) were used as ball milling medium. The weight ratio of powder:balls was fixed at 10:1. Additionally, 5 wt% ethanol was used as a process control agent to avoid cold welding during ball milling. 2.2.

One solution to limit such a reactivity is the use of ball milling process. The main interest of the ball milling process is to form large agglomerates with a micrometric size composed of nanocrystallites, as shown in Fig. 1. Such a microstructure is obtained after repeated fracture/welding processes induced during the milling.
