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. This energy input is largely a function of the periph -
