METHOD FOR SEPARATING AND COLLECTING SUSPENDED IMPURITIES CONTAINED IN CONSTRUCTIONAL WASTES

摘要

PURPOSE: A method for separating and collecting suspended impurities contained in constructional wastes is provided to enable the selective extraction of waste concrete lumps only thus allowing the production of high quality regenerative aggregate. CONSTITUTION: The method for separating and collecting suspended impurities contained in constructional wastes comprises the steps of: dropping the constructional wastes; blowing wind toward the dropping wastes so as to separate the suspended impurities contained the wastes; immersing the dropped wastes so as to allow the impurities to be risen onto the water surface; generating one-way water currents so as to guide the impurities; injecting water to the moving impurities; and continuously supplying water so as to cause the collected impurities to be discharged along with the water.
