AGGREGATE REGENERATING APPARATUS

PROBLEM TO BE SOLVED: To provide an aggregate regenerating apparatus in which high quality aggregate is regenerated by efficiently removing a cement paste portion from coarse aggregate and fine aggregate at a low cost. SOLUTION: An aggregate regenerating apparatus 10 is provided with a plurality of vertically movable push rods 1 in a vessel 2. A plurality of the push rods 1 are attached to a plate like push rod attaching member 3 in a grid patterned state in a horizontal view and the push rod attaching member 3 is connected to a plate like supporting member 4 via guide rods 5 provided on the 4 corners. The tip part 1a of each push rod 1 has a cross-section decreased step-wisely toward the tip and has a vertical height different from the vertical height of the tip part 1a at least of the adjacent push rod 1. A horizontally movable feed conveyer 8 is provided in a feed port 2a and a discharge conveyer 9 is provided in the discharge port 2b. Vibration feeders 7, 7 composed of a motor and for vibrating the bottom surface 2c are provided on the bottom surface 2c of the vessel 2. COPYRIGHT: (C)2006,JPO&NCIPI
