A Review of Methods for Synthesis of Al Nanoparticles ...
Mechanical milling as a solid state synthesis usually performed using ball milling equipments that generally divided to "low energy" and "high energy" egory based on the value of induced the mechanical energy to the powder mixture [13]. The objective of milling is to reduce the particle size and blending of particles in new phases.
Alpine SO Super Orion Ball Mill
Ball mills are giant drums that are filled to between 30 and 40% of their volume with freely moving grinding media – in this case balls. The diameter of the balls is between one and several centimetres to suit the appliion – smaller balls for fine milling results and larger ones for coarser milling tasks.
Grinding, milling, crushing
b) Ball mills The mill consists of a slowly rotating, horizontal steel cylinder, half filled with steel balls ( – 15 cm in diameter). The final particle size depends on .
