PURPOSE: Provided is a vertical shaft impact crusher for dual crushing wherein an impact bar is placed at an outlet side of a rotor to crush aggregate two times so that it raises efficiency in crushing. CONSTITUTION: In the vertical shaft impact crusher which comprises the parts of: a hopper which includes a level sensor; a gate which is placed at upper side of a rotor housing to control the feeding of the aggregate; a chute which is placed under the gate to secure a feeding passage in opening; a rotor shaft(20) which fixes a pulley connecting to a motor at lower side of the chute; and a rotor(26) which allows a tip(22) to hit the aggregate firstly when the aggregate is thrown to one side of an outlet(32), the vertical shaft impact crusher for dual crushing is characterized by allowing the rotor to get the impact bar(24) and then hit the aggregate secondly.
