BNNTs were typically synthesized by the prolonged (approximately 150 h) high-energy milling of pure boron or h-BN powder using stainless-steel milling vessels and hardened steel balls in a pressurized (∼2.3 × 10 3 Torr) NH 3 atmosphere. The milled material was then annealed at high temperature (>1000 °C) in an N 2 atmosphere for ∼10 h.

The operating principle of the ball mill
Energy consumption for ball mills is a function of many factors: the physical properties of the ground material – its specific gravity and hardness; the degree of drum filling by grinding balls; the number of drum rotations, etc. Ball mills have low efficiency – no more than 15%. Energy is mainly consumed on the wear of grinding balls and ...

The results demonstrate that the energy required for ball milling increases with increasing milling time, and the energy input for BMCS120 reaches 19.34 MJ kg −1 DM (dry matter). On the contrary, the required mixing energy during high-solids EH decreases with increasing milling time, due to the dramatic decrease of viscosity after ball milling.
