CONSTITUTION: The method comprises as follows: (i) feed waste to a jaw crusher (1) for crushing; (ii) separate steel bars and metals through a magnetic conveyor (3); (iii) separate earth and sand through a centrifugal machine (4); (iv) classify waste through a blower (7); (v) secondary crush waste at an impact crusher (9); (vi) classify waste through a double vibrating screen (10) by three stages for removing waste through conveyors (8,8') and blowers (7,7'); and (vii) classify waste through an underwater conveyor (11) and a screw conveyor (12) into three kinds of aggregates for recycling at a site. |
