A system for delivering a proper proportion of water and starch to form a slurry on a continuous basis responsive to the rate required for the production of gypsum board has a water input controller and a starch input controller to control the rate of water and starch input to a mix/hold tank and a starch output controller to control the output of slurry from the mix/hold tank to the gypsum board production line. A programmable logic controller monitors the output rate and density of the delivered slurry, compares them to a target value and signals the input controllers and/or the output controller to adjust the input and output rates accordingly. |
