The separator's rotor runs inside a ring of guide vanes, which facilitate intake of the material entrained in the air from the mill into the rotor. The rotor rejects coarse particles, sending them back to the grinding table for further grinding. You can select the desired fineness by simply adjusting the rotor speed for the separator.
