Small scale milling trials to modify particle size distribution

Small differences between Small scale mill and MACRO-PACTOR can be observed in the extent of the strongest particle fraction between 1000 m and 1400 m, which lead to a slight shift of the particle size distribution towards coarser particles for the Small Scale Mill. The extent of this small deviation seems to be material specific.
