AGGREGATES HAVING IMPROVED PARTICLE SHAPES AND FOREIGN MATERIAL SORTING SYSTEM FOR OBTAINING HIGH QUALITY AGGREGATE

摘要

PURPOSE: Provided is an aggregate having an improved particle shape and a foreign material sorting system for sorting foreign materials included in the aggregates, thereby obtaining high quality aggregates only. CONSTITUTION: The foreign material sorting system includes a vibration generator(1); an injection conveyor(4) for injecting crushed materials into the vibration generator(1); a discharge conveyor(4') to which the crushed materials fall down, whereby foreign material included in the crushed materials is separated therefrom by air pressure formed by a nozzle(5); a vibrating motor(12) fixed by a bracket(13) onto the lower portion of a housing(11) with an inlet and an outlet; a support(15) having a plurality of springs(14,14') formed on both lower sides of the housing(11); and a foreign material remover installed on the passage of a duct(6).
