Question: what do you research the most?

I have a stirred mill, which is basically just a big cup with a stirrer. I put metal beads in there with a powder so that when the stirrer is on, the metal beads bang together and break the powder up into finer particles. I try changing things like the mixer speed and the amount and type of metal beads to be able to break up the powder with the least amount of energy costs.
