A rotary mineral breaker of the type having a rotor (1) able to rotate about a substantially vertical axis. The rotor has an inlet for mineral pieces which are to be broken. The inlet is substantially parallel to the rotary axis when viewed from above. The rotor also has at least one peripheral exit port (9) for such materials, that is minerals after breaking, to exit radially of the rotor into a surrounding mineral material interaction zone (6). The rotor has a feature that at the or each peripheral port, but carried by the said rotor, there is means providing an exit port geometry which at least includes a mineral piece there to accumulation weir (3) to encourage by the appropriate profiling of the bed, those mineral pieces accelerating, in use, on the bed of retained mineral pieces (5) to exit over the weir (3) away from the upper regions of the retained bed (5). |
