The invention relates to a magnetic-vibration swing-impact-type ball milling device which includes: a pedestal; a door-shaped support arranged vertically thereon; two cantilevers which are fixed on the top of the door-shaped support in horizontal direction; an electromagnetic coil arranged below the two cantilevers and on the door-shaped support; an AC frequency converter electrically connected to the electromagnetic coil; and a cylindrical vibrator unit inserted in the electromagnetic coil, wherein two ends of the cylindrical vibrator are connected to the two cantilevers through pulling ropes respectively, so that a floating reciprocating movement system is configured by means of the cylindrical vibrator unit, the pulling rope, the electromagnetic coil and the cantilevers. When the device works, the AC frequency converter controls the electromagnetic coil to generate an alternating magnetic field, and the cylindrical vibrator unit reciprocatingly moves under the effect of the alternating magnetic field. Compared with the prior art, by means of the movement system driven by magnetic force, the system has no mechanical transmission parts, is low in movement resistance and mechanical noise, is convenient to operate, clean and maintain, is safe and reliable, has long service life, and has great application prospect.
