Get Price2013-12-1 · The ball diameter of 5 mm is optimal at 50 rpm of rotation speed (the resultant average particle size of the milled powder is 2.3 μm), ball diameter of 3 mm is optimal at 100 rpm (1.4 μm), and 2 mm is optimal at 153 rpm (0.84 μm). From this result, it can be said that the optimal ball size for efficient milling decreases with the rotation
Get PriceBall milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys. In fact, ball milling process is not new and dates back to more than 150 years. It has been used in size comminutions of ore, mineral dressing, preparing talc powders and many
