<p>The present invention relates to a vertical shaft impact crusher in which a rotor protection layer formed of particles of an object that is crushed is disposed in a rotor. The present invention provides a rotor (5) rotating with respect to a rotation shaft vertically extending to accelerate a target object to be crushed (hereinafter, referred to as a″crushed object″) by using centrifugal force. The rotor (5) includes: a rotor upper plate (55) having a rotor upper plate hole (551) that is an insertion hole of the crushed object inserted into the rotor and defining an upper portion of the rotor; a rotor lower plate (53) spaced apart from a lower portion of the rotor upper plate and defining a bottom of the rotor; a rotor main wall (54) disposed between the rotor upper plate and the rotor lower plate and connected to each of the rotor upper plate and the rotor lower plate, the rotor main wall (54) being spaced apart from the rotation center of the rotor; and a circular hole (541) defined in the rotor main wall (54) to be an outlet through which the crushed object accelerated in the rotor is discharged from the rotor.</p> |
