EQUIPMENT FOR PREPARATION OF RECLAIMED WET COARSE AGGREGATE AND CRUSHED SAND FROM CONSTRUCTIONAL WASTE

摘要

PURPOSE: Provided is an equipment for preparing reclaimed wet coarse aggregate and crushed sand by using constructional waste and previously removing soil powders from raw material to improve quality of final product. CONSTITUTION: The equipment comprises a hopper(1), a vibrational supply device(2), a hand-picking conveyor(3), first to fourth vibrational screens(10,21,5,7), first to fifth crushers(20,51,8,9,19), a sorting tank(30), first to third transfer belts(6,8a,19a), and a crashing device(90) to remove residue such as soil powders from broken materials obtained the third and the fourth screens(5,7) then give final crushed sand. After then, by treating residual materials in the fourth screen, the coarse aggregate is produced. The first screen(10) has first and second selectional nets(11,12). Similarly, the third screen(5) has first to third nets(5a,5b,5c) while the fourth screen(7) has first and second nets(7a,7b) and an isolation plate(7c) between the nets.
