Abstract:
1. A bead mill for performing wet comminuting comprising: 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; said bead mill further comprises a separator containing a separator chamber disposed substantially vertically, and a laminarization portion providing an upward laminar suspension flow within the separator chamber, to separate the milled particles from the milling bodies and raw particles, the size of the milled particles below which they are separated depending on the flow velocity of said upward laminar suspension flow.
