The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%15% above the ball charge for total of 23% ...

Ball 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 ...

 · The main factors that influence the particle size reduction for ball milling is speed and also the time taken. From the results that we get from the experiment, it shows that the higher the speed and the longer the time taken the more the particle reduce the size. As we can see in the table, the amount for the smallest size which is 150 μm higher for speed 5 at 20 minute. None of the particle ...
