High energy ball milling process for nanomaterial synthesis
The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling ...

Lab Report 1 and 2: PRACTICAL 1 : BALL MILLING
As a conclusion, the higher the speed of the sets, the higher the products amount produced in desired size range. The high amount of products produced can also be because of the longer duration of the sets in ball milling process. However, the speed has more effects on products produced compared to duration of the sets in this experiment.
