milling of porous silicon microparticles | springerlink

Milling of much larger batches requires equipment with high throughput. A rotor mill is a convenient tool for achieving particle size reduction with throughput up to 20 g/min and typical D 90 ’s of tens of microns (possibly lower, depending on the nature of the material). A typical laboratory-scale unit is the Fritsch Pulverisette P14 (Fig. 1).
