Small differences between Small scale mill and MACROPACTOR can be observed in the extent of the strongest particle fraction between 1000 µm and 1400 µm, 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. They are caused by the other process parameters of the ...
