PURPOSE: A foreign substance sorting apparatus and a stabilization method of a construction waste soil and stone is provided to sort out and remove foreign substances which is contained in the construction waste soil and stone; and switch from the construction waste soil and stone to an environmentally stable substance by reducing the pH of the construction waste soil and stone. CONSTITUTION: A foreign substance sorting apparatus comprises a main body(10) which applies vibration as a vibration motor is equipped; two mesh nets(20) which is inclined downward to be discharged to the outside of the main body as the foreign substances, which is separated by vibration after separation from the construction waste soil and stone, moves forward; and an air blower(30) which makes the construction waste soil and stone ,that falls from the mesh net as it failed to pass the mesh net, to separated by blowing. A fall inducing board(40) is equipped with an interval with the air blower in front of the air blower and the fall inducing board makes the construction waste soil and stone, in which foreign substances are removed by air blowing of the air blower during falling after failure to pass the mesh net, to fall following the fall inducing board while it collides with the fall induction board. Among two mesh nets, a mesh net arranged in the upper area is 5 millimeter mesh net(21) with 5 millimeters of the mesh size and a mesh net arranged in the lower area is 3 millimeter mesh net(11) with 3 millimeters of the mesh size. The first discharge guide(190), which is extended to longitudinal directions are formed in the first discharge hole(19) to guide the discharged foreign substances to fall in an area that is far from the main body. The second discharge guide(180) is equipped in the second discharge hole(18) to guide the fall position of the foreign substances that is discharged. |
