Planetary ball milling (PBM) was carried out using a Fritsch Pulverisette 7 planetary ball mill.2c), is a high energy mill (Angelo and Subramanian, 2008), where shearing and compression are more prevalent than high velocity collisions.
Planetary ball mills are perhaps the most commonly used ball mills in laboratories for the sample preparing of soft to hard, brittle and fibrous materials.The name of this mill type derives from its unique kinematics: the grinding bowls, which are mounted on the rotating sun disk, rotate in the opposite direction around the centre of this disk.
