A nano ball mill is provided to offer strong dispersion force without a screen by circulating a bead compulsorily through a vortex generated by a turbine and an impeller. A nano ball mill includes the followings: a rotary shaft(100) having a lower member(110), an upper member(120), and an intermediate member(130); a turbine(200) having a plurality of wings(210) and combined with the top of the lower member; a disc(400) of a cylindrical shape in which the rotary shaft, turbine, and the disc are inserted, and combined with the upper member; a plurality of beads(500) arranged between the disc and a casing; an impeller(600) generating a vortex; a bottom plate(410) having a raw material injection hole(410a) in center; and a sealing member sealing an interval of the casing and the upper member.
