Section snippets Experimental. Mechanical milling was performed by using a planetary ball mill (PBM) under various experimental conditions. Copper powder (% purity, median particle size x 50 = 45 μm, Aldrich chemistry) was used as shown in Fig. 1. Mechanical alloying (MA) was carried out at two types of rotation speeds: low (10, 50, and 100 rpm) and high (300, 500, and 700 rpm).

It was also revealed that the stirred mill and ball mill had varied effects on the minerals (Fig. 21). For all of the minerals, stirred milling was found to be producing more liberated particles than the ball milling and the difference between them became almost disappear through the fine grinding (from p 80 of 330 µm to 38 µm).

also tablet compaction. To avoid uneven granule size distribution, milling is done post granulation. There are different kinds of mills such as hammer mills, ball mills, conical screen mills etc. which can be classified on the basis of type of force applied to break the particles. This study mainly focuses on conical screen mill.
