かからない利点がある。(Effects of the Invention) As described above, in the present invention, raw material slurries such as rough stone, clay, and reclaimed soil are prepared in their respective tanks, and the flow rate of each raw material slurry is based on the detection value of the flow rate detector. It was controlled by a control valve to guide each raw material slurry together with water to a mixing tank at the same time to continuously perform mixing. Therefore, the rough stone slurry, clay, auxiliary raw material and water are mixed in one ball mill. Compared with the conventional method, the frequency of opening and closing the lid of the ball mill can be reduced, and the generation of dust accompanying it can be prevented. In addition, the amount of rough stone that can be crushed can be increased to 1.5 to 2.0 times that of the conventional method because clay is not added and mixed in the ball mill, and various mixing ratios of each raw material can be freely changed by the flow rate detector and control valve. It is also possible to make a base material of the composition. Further, according to the present invention, since it is possible to continuously mix the respective raw material slurries, there is an advantage that preparation is not troublesome.
