The present invention relates to an impact screen and an impact sorting method. The impact screen is intended to sort out particles by size by allowing the particles to collide on a screen net after accelerating a mixture of particles to be sort out at high speed. According to the present invention, the impact screen comprises: an accelerator (2, 3) accelerating the particle mixture to be sort out by size; at least one screen net (41, 44) disposed to be separated from the accelerator on a moving path of the accelerated particle mixture, so as to allow the particle mixture accelerated by the accelerator to collide; and a chute (5) separating particles into screen net-penetrable particles with smaller size than a network of the screen net and screen net-impenetrable particles with larger size than the network of the screen net so as to discharge the same. |
