Why I cannot get Alumina particle in nanosize scale using.

We have milled different oxides from micron-size powder up to the nanoscale (below 20 nm) using a "planetary milling". The milling parameters were similar. Speed (rpm) 300 rpm. BTP (ball to powder ratio) = 7:1 (7 gr of balls for each 1 gr of powder). time = always above 30 h. In our case, we stop the process each 6 min.
