摘要

PURPOSE: An apparatus for pulverizing recycled aggregate is provided to quickly and easily repair a mantle core. CONSTITUTION: An apparatus for pulverizing recycled aggregate comprises a straight rotation shaft(21) having a mantle core(22) at the center of a frame(10). The mantle core is rotationally mounted to connect through a first power source(23) and power transmission member(24). A cave which surrounds outer circumference is mounted at the outer frame of the mantle core. A divided cave comprises a expanding device expanded by radially being rotated. The expanding device comprises two brackets which is parallelly provided at the external surface of the divided cave; a driving frame(36) provided in a bucket form; and a hinge pin which is rotationally connected at a first bracket mounted at the outer frame of the mantle core.
