APPARATUS CRUSHING AND GRINDING FOR REMAKING AGGREGATE FROM CONSTRUCTION WASTE

摘要

A crushing and grinding apparatus for making a recycled aggregate of high quality from construction waste is provided to improve production efficiency and make a recycled aggregate with uniform and excellent quality by enhancing an impact crusher for making a recycled aggregate. The crushing and grinding apparatus comprises: an upper slot(12) provided on the top of an impact crusher and longitudinally formed so as to prevent the overflow of material; a rotor slot(30) provided in the impact crusher and for preventing the overflow of material and obtaining a quantitative input effect; a rotor(20) provided below the rotor slot and for increasing the crushing efficiency by widening the diameter of an upper panel as much as the diameter of a lower panel; and a distributed crushing unit(21) provided in the rotor and for increasing the crushing efficiency and improving a particle shape by the rotation of a crushing rotary blade.
