Abstract
The invention relates to a rotary mineral breaker, a rotor and a method of using a rotary mineral breaker. The rotary mineral breaker includes a rotor having an inlet for mineral pieces at and/or substantially parallel to the rotary axis thereof from above and at least one peripheral exit port for such materials to exit in the same and/or a modified form radially of the rotor into a surrounding mineral piece interaction zone, the rotor being characterised in that in use for each exit port there will be a retained bed of mineral pieces having (a) a greater vertical extend inwardly of the exit port than at the exit port itself and/or (b) starting higher inwardly that at the exit port itself and being further characterised in that at the trailing boundary of each exit port there is at least a sacrificial member which acts or will act directly or indirectly as a weir for the retained bed of mineral pieces and over which other mineral pieces may be flung, said retained mineral pieces extending inwardly to a backup form which limits the inward intrusion of the retained bed.
