Slurry production system

摘要

A slurry mixing and pumping system adapted to automatically control both slurry viscosity and product output volume. Water and raw gypsum delivered to a mixing vat are thoroughly blended by a hydraulically powered agitator blade within the vat. Hydraulic pressure variations experienced by the agitator motor are translated into pneumatic viscosity control signals by a process controller. An air actuated water valve driven by the controller varies water input into the vat to effectuate viscosity correction. Means responsive to vat head level controls output volume.
