It can be seen that most of the milled CL-20 microparticles form sphere shape with smooth surface after ball milling, whereas the starting material presents spindle shape (Additional file 1: Figure S2c). Additionally, the average particle size of the milled CL-20 is 200 nm, which is clearly smaller than that of the raw CL-20 (300 μm).

The balls which could be of different diameter occupy 30 -50% of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
