The Efficiency of Grinding - Pharmaceutical Engineering

THE EFFICIENCY OF GRINDING. Extensive investigation of the relation between the energy supplied to a mill and the size reduction achieved has been carried out. The efficiency of the process reflected by such a relation is of small importance in pharmacy because the applications are limited. For completeness, however, they are considered below. Most of the energy
