Disclosed are an automatic crushing and sorting equipment of garbage and a method for sorting foreign substances in the garbage. The equipment includes a case having a perforated base plate and a discharge outlet for sorting out and discharging organic matters and foreign substances in garbage charged through a hopper; a striking cover plate for letting the garbage carried from the case being collided and crushed; a vertical partition for isolating the perforated base plate from the discharge outlet; a drive shaft passing through the case in a longitudinal direction of the case such that both end parts thereof projecting from both sides of the case are rotated; and a plurality of hammer mill assemblies successively and fixedly installed on the drive shaft, and being sequentially titled while maintaining a predetermined deviation in angle between unit members so that the garbage is crushed into a micro-sized particles and carried by maintaining a minute gap between end parts of the hammer mill assemblies and the inner surface of the striking cover plate to collide the garbage with the striking cover plate. The present invention has an advantage of recreating available resources and minimizing environmental pollution since a huge volume of garbage dispensed from households, restaurants, etc. are crushed into a wanted size and at the same time foreign substances in the garbage are automatically sorted out and completely separated.
