A newly developed bead mill with an improved grinding media separation system allows use of beads with diameters down to 50 m. While this may not seem significant, for dispersing NanoParticles one of the methods for preventing damage to the NanoParticles is to run the machine at a slow rotor speed. A slow rotor speed reduces the separation ...
