How many samples can planetary ball mill grind at one time ...
At the same time, because there are grinding balls in the ball milling tank, the size of grinding balls is 1 / 3, that is to say, each can be loaded with 1 / 3 of the samples. the remaining 1 / 3 is the operating space, so when selecting a machine, if you need to produce 4L of materials at a time, you need to select a relatively large machine.

Solids | Choose the Right Grinding Mill | Chemical Processing
Grinding time is related to media diameter and agitator speed via: T = KD 2 /N 1/2. where T is the grinding time to reach a certain median particle size, K is a constant that depends upon the material being processed, the type of media and the particular mill being used, D is the diameter of the media, and N is the shaft rpm. This equation shows that total grinding time is directly ...
