A milling apparatus comprising a milling chamber loadable with a grinding charge; an inlet to the milling chamber via which a material to be milled is introduced into the milling chamber; and an outlet from the chamber via which milled material is extracted from the milling chamber; wherein a rotatingly driven centrifuge grinding separator is located within the milling chamber which separator comprises: an upper plate formed with a plurality of diagonally formed through slots; a lower plate formed with a plurality of diagonally formed through slots; and a ring located between the upper and lower plates formed with a plurality of diagonally formed through slots; arranged such that rotation of the central ring formed with the diagonal slots continually pressurizes such a grinding charge so as to force such a grinding charge from the centre of the separator upward and over the periphery of the separator and downward and under en the periphery of the separator and rotation of the upper and lower plates formed with the diagonal slots pulls and draws such a grinding charge back into the centre of the separator.
