Ball Milling Research - ResearchGate

I have mineral wollastonite within average particle size of D50 = 3 micrometer, I am trying to decrease the particle size to nano scale, using a planetary ball milling, I hope I can understand the following factors; 1- the ball to powder ratio, how can I calculate it. 2- using a wet ball milling, so how may I know the concentration of...

Why I cannot get Alumina particle in nanosize scale using ball ...

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...
