Micromilling of uniform nanoparticles - fritsch.de

The micromill uses rotation speeds of up to 1,100 rpm and an acceleration force of 95 g for a resulting energy application roughly 150% greater than that of classic planetary mills. This extraordinary milling energy results in more economical and efficient milling of particles, providing us with considerably finer grinding results in shorter times.
