The invention belongs to the field of self-synchronous vibration machines, and discloses a multi-machine-driven circular motion vibration crusher. The crusher comprises an inner mass body, an outer mass body, a vibration damping spring and two vibration exciters. By means of the self-synchronizing principle, the two vibration exciters are symmetrically arranged on the inner mass body, and are arranged in a large distance mode. During work, two eccentric rotors operate synchronously, and the phase difference of the two eccentric rotors can be stabilized to be close to 0 DEG so as to drive the inner mass body to rotate at a high speed in the outer mass body cavity; and the double-machine synchronous driving can achieve large crushing ratio and vibration intensity. According to the crusher, the innovation of the novel vibration crusher is realized by combining the self-synchronizing principle of the two vibration exciters. The crusher is suitable for crushing ultra-hard alloy ores (such as chromium alloy ores), furnace slag of steel factories and the like.
