A bead mill for performing wet comminuting including a stationary vessel having an internal wall and forming a milling chamber to be filled at least partly with milling bodies, raw particles and a carrying liquid to form a suspension within the milling chamber; an activator shaft, rotatable around an axis concentric with the stationary vessel and a rotating activator connected to the activator shaft, to comminute said raw particles to produce milled particles; characterized in that said bead mill further comprises a separator, containing a separator chamber disposed substantially vertically, a laminarization portion providing an upward laminar suspension flow within the separator chamber, to separate the milled particles from the milling beads and raw particles depending on the flow velocity of said upward laminar suspension flow.
