The control unit controls the amount of coarse aggregate and fine aggregate supplied to the aggregate dryer by adjusting the conveying speed of the conveyor belt with the opening and closing portion of the hopper described above.

Coarse aggregate and fine aggregate conveyed by the conveyor belt is heated in the aggregate dryer to remove moisture (S20).

In a preferred embodiment of the present invention, an aggregate dryer having a conventional structure is used. Preferably, the aggregate dryer is in the shape of a circular tube and the coarse aggregate and fine aggregate conveyed by the conveyor belt through one end is introduced into the inside. More preferably, the transfer member is installed inside the aggregate dryer spirally rotated from one end to the other end along the inner circumference, and a heating unit for heating the inside of the aggregate dryer is formed along the inner circumferential surface of the aggregate dryer to directly heat the aggregate. do. The coarse aggregate and fine aggregate introduced through one end of the aggregate dryer are transferred to the other end by the transfer member, and are heated to 150 to 250 ° C. by the heating unit during transfer, and preferably heated to 170 ° C. to remove moisture. The heat-drying of the aggregate in advance is because if the aggregate contains moisture, the bond strength with other additives, for example, with the sulfur polymer, is reduced because of the moisture. In addition, when the aggregate or the like is preheated to a predetermined temperature by an aggregate dryer before being put into the mixer to be described later, when the concrete composition containing the aggregate is introduced into the mixer, there is also an effect that a smooth mixing operation can be performed without a temperature decrease.

Unlike the embodiment of the present invention, when the fruit oil is moved by its own weight from the upper part to the lower part of the tank 100, the moving speed of the fruit oil is too fast, so that the heat transfer from the fruit oil to the SPC inside the tank 100 is not sufficient. It will come down to the bottom of the tank 100 without. Therefore, the fruit oil is moved from the lower part of the heating line 30 to the upper part by the pump, so that the heat transfer is made sufficiently from the fruit oil to the SPC, thereby heating the SPC.

As described above, the heating line 30 connected to the fruit oil input line is installed across the bottom of the tank 100 several times in the tank 100, and is installed in a spiral shape having a predetermined pitch from the bottom toward the top.

Rotating blade 46 may be installed. As described above, when SPC is heated to 150 to 160 ° C. or higher, it is important that the SPC not be heated to a higher temperature because various physical property changes occur, such as a sudden increase in viscosity and the release of sulfur components. Maintain a temperature of ˜140 ° C. In the present invention, the SPC inside the tank 100 is evenly mixed by the rotation of the rotary blade 46, and not only a part of the SPC is heated by the fruit oil of the heating line 30, but by the rotation of the rotary blade 46.
