synthesis of nanomaterials by high energy ball millingsynthesis of nanomaterials by high energy ball milling w. cao . it is a ball milling process where a powder mixture placed in the ball mill is subjected to high energy collision from the balls. this process was developed by benjamin and his coworkers at the international nickel company in the late of 1960. the impact energy of the
ball mill the ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non ferrous metals. the ball mill can grind various ores and other materials either wet or dry.
