VERTICAL SHAFT IMPACT CRUSHER AND ROTOR THEREOF

摘要

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 side 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 side 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 side wall 54 and is an outlet for the object for crushing accelerated by the rotor to come out of the rotor.
