To enable raw material slurry to be supplied to a paper making machine to be stably supplied to the paper making machine over time while the variability of the slurry concentration is controlled and thereby, produce a high-quality green sheet.
A raw material slurry mixing and accumulation box 2 is arranged halfway through a slurry supply path leading to a paper making machine from a chest 1 and a raw material slurry contained in the chest 1 is once transferred to the mixing and accumulation box 2. At the same time, information relative to the concentration of the raw material slurry is collected in the mixing and accumulation box 2. Further, diluting water is charged while the input is adjusted based on the obtained concentration data and both slurry and water are mixed to adjust the concentration of the raw material slurry. In addition, the raw material slurry whose concentration is adjusted is supplied to the paper making machine under control.
