Advantages of ball milling process: 1. Nanopowders of 2 to 20 nm in size can be produced. The size of nanopowder also depends upon the speed of the rotation of the balls. 2. It is an inexpensive and easy process. Disadvantages; 1. As the process is not so sophisticated, therefore the shape of the nanomaterial is irregular. 2.

After addition of graphite oxide, some wrinkles are observed on its surface. This reveals that GO sheets are deposited on the surface of CL-20 during the ball milling process. It follows from SEM results presented that the retention rate of GO increased with increasing the addition of graphite oxide.

Based on powder particle size and impact energy required, balls with size of 10 to 30 mm are normally used. If the size of the balls is too small, impact energy may be too low for alloying to take place. In order to increase impact energy without increasing the rotational speed, balls with high density such as tungsten balls may be employed.
