Abstract: PROBLEM TO BE SOLVED: To improve the control system of a repulping device having a container for pulp, a container for an aqueous slurry and a rotary blade for mixing the pulp with water to produce the aqueous slurry, thereby making it possible to continuously produce the aqueous slurry having a uniform slurry concentration without being affected by variations on processes. SOLUTION: When pulp is introduced from a supply device 2 into a container 6, the introduction of the pulp into the container is detected with a supply sensor. A control device 8 computes a water volume and a water flow rate to be fed into the container to obtain a prescribed slurry concentration in response to a pulp introduction signal, and subsequently outputs a signal exhibiting the water volume. A volume control means 62 controls the supply of water into the container in response to the computed water volume signal. The control device 8 further outputs a signal exhibiting the computed water flow rate. A flow rate control means 64 supplies the water into the container at the computed flow rate in response to the computed water volume signal and the computed flow rare signal. The water level sensor 110 of a slurry reservoir 14 monitors a slurry level in the slurry reservoir 14.
