Why Dry or Wet Milling?
For instance, size reduction of hard particles on a rotor/stator wet milling process is related to impact. As the rotor/stator slots align material is conveyed through the openings via the liquid carrier and lift produced by centrifugal motion of the mill's rotational speed. This motion creates velocity.
