PURPOSE: A device for manufacturing an aggregates of good quality using construction wastes is provided to minimize treating cost by suitably treating construction wastes according to in-situ conditions, to maximize regeneration efficiency of the aggregates, and to manufacture the aggregates having various size. CONSTITUTION: The manufacturing device comprises a first treating portion(100) which has a jaw crusher(120) for crushing an aggregates introduced from a hopper(110) in certain grain size, a vibrating feeder(130,140) located in back and forth sides of the jaw crusher, a vibrating screen(170) located in one side of the vibrating feeder for separating particles having size below 40mm from particles having size above 40mm, and a second treating portion(200) which has a plurality of vibrating feeders(210,220) for eliminating clay from the first treated aggregates and a cone crusher(240) for recrushing the aggregates supplied from the vibrating feeder. The oversized aggregates which are not separated at a v
