The present invention relates to a vertical shaft impact crusher comprising a rotor having a rotor protection layer which is formed therein and consists of particles of objects to be crushed. The present invention relates to a rotor (5) which rotates about a rotation shaft extending in a vertical direction and accelerates an object for crushing by centrifugal force. The rotor comprises: a rotor upper plate (55) which forms the upper portion of the rotor and comprises a rotor upper plate hole (551), which is an inlet for the object for crushing which is inserted into the rotor; a rotor lower plate (53) which forms the bottom of the rotor and is disposed to be separated from the lower portion of the rotor upper plate; a rotor main wall (54) which is disposed between the rotor upper plate and the rotor lower plate so as to be coupled to the rotor upper plate and the rotor lower plate, the rotor main wall being disposed at a position spaced from the rotation center of the rotor; and a circular hole (541) which is formed on the rotor main wall (54) and is an outlet for the object for crushing accelerated by the rotor to come out of the rotor. |
