Mechanical Grinding Nano Particle :

Effectively Grinding And Dispersing Nanoparticles Using A ...

2019-12-2  The production of stable suspensions or dispersions of nano particles actually requires a comminution process, such as a small-media mill provides. On an industrial level, this grinding of coarser particles into the nanometer range or dispersing agglomerated nano-sized primary particles is done with a bead mill, even though the high energy and bead speeds typically required can lead to material contamination or the destruction of the crystalline structure of the particle.
