Using an agitator bead mill for nanoparticle dispersion

Mild dispersion versus real comminution The bead mill reduces material to nanoparticles in one of two ways — mild dispersion and real comminution. The difference between mild dispersion (disaggregation or deagglomeration) and real comminution (reducing parti-cles below their primary particle size) is a matter of energy input.
