Abstract
An apparatus for introducing powdered solids into a liquid stream at a controlled rate to form a slurry. Solids are metered to an eductor where they are educted into the liquid stream. An automatic cycle timer-controller purges eductor, hopper and piping of residual solids before solids flow is initiated, and following solids flow. Pressure sensors detect low water pressure and/or plugging, shutting off liquid and solids flow.
