In order to achieve a milling apparatus which may be disposed vertically or horizontally or at any convenient angle, and in order to achieve a greater degree of efficiency the milling apparatus according to the invention comprising a radially symmetrical sleeve having an axial passageway with an upstream inlet and a downstream outlet or vice versa, a radially symmetrical rotor located within the sleeve, one of the rotor and sleeve being rotatable relative to the other, the diameter of the rotor being less than the diameter of the sleeve at each axial position to define an annular passageway between the rotor and sleeve, one or both of the surfaces of the rotor (2) and sleeve (9) having formations (4) adapted to increase the surface area encountered by particles in a fluid flow form the inlet to the outlet. |
