Ball milling method for nanomaterial synthesis
During the high-energy ball milling process, the powder particles are subjected to high energetic impact. Microstructurally, the mechanical alloying process can be divided into four stages: (a) initial stage, (b) intermediate stage, (c) final stage, and (d) completion stage. (a) At the initial stage of ball milling, the powder particles are ...

So, it may be the case that Pd was oxidized by K 2 S 2 O 8 and formed chelates with chlorine during the ball milling process. Hence, NaCl and K 2 S 2 O 8 played the role of ligand and oxidant, respectively, during the ball milling process. It can also be seen from Fig. 2 that the ball milling process had little effect on the recovery of Zn ...

Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
