Ideally, the grinding balls are 3 times the size of the largest sample piece. The numbers and sizes of balls given in the table below follow this rule of thumb. To pulverize, for example, 20 ml of a sample consisting of 8-mm sized particles, the use of a 50 ml jar and 25 mm balls is recommended.
Ball Mill
The ball mill process is a mechanical-chemical process that uses mechanical force to induce the chemical and structural change of certain materials (Amusat, Kebede, Dube, & Nindi, 2021). A mechanical mill is a type of grinder used to grind and blend a bulk material into extremely fine nanosize powder using different sizes of milling balls.
