The invention relates to nanometer crushing of powder materials and discloses a vacuum stick beating nanometer crusher. The vacuum stick beating nanometer crusher is characterized in that a machine table is provided with slide ways for electromagnetic hammers, and the electromagnetic hammers are arranged in the slide ways; the two slide ways for the electromagnetic hammers are symmetrically arranged into a group, and the two slide ways in the group are symmetrically arranged with the axis of an anvil stick as the center; the vacuum stick beating nanometer crusher with the symmetrical slide ways is provided with the one or more electromagnetic hammers; the grouping number of the electromagnetic hammers of the vacuum stick beating nanometer crusher of the optimal design is that the number ofthe electromagnetic hammers are arranged around the anvil stick, wherein the number is a multiple of three, namely three, six, nine and so forth; the axis of the anvil stick coincides with the centerof the machine table; the machine table with the center coinciding with the anvil stick is provided with spring plates to be connected with the electromagnetic hammers; lower segments of the spring plates connected with the electromagnetic hammers are inserted into insertion holes formed in the machine table; the upper segments of the spring plates with the lower segments inserted into the insertion holes of the machine table are inserted into grooves formed below the tail ends of the electromagnetic hammers; the electromagnetic hammers are connected with counter-beating sticks through flanges, and the counter-beating sticks are driven by the electromagnetic hammer groups; and the rotating anvil stick is beaten by the two counter-beating sticks at the same time to crush the nanometer powder materials.
