The invention relates to an apparatus, system, and method for the bulk blending of dry component materials to produce a blended product mix. The apparatus utilizes a special construction that allows multiple bulk dry materials to be added simultaneously to create a blended mix compliant with a desired or specified mixture of cement components. The system is automated by use of a controller, and provides real-time data to a user as to rates and amounts of materials blended and delivered over time.

Hemihydrate and/or anhydrous Type III gypsum granules derived from wasted gypsum boards are fed into a flow path of an aqueous gypsum slurry containing dihydrate gypsum, are mixed with the gypsum slurry, and are fed into a deposition tank of dihydrate gypsum. The gypsum slurry is fed from an inlet of the flow path, and the hemihydrate and/or anhydrous type III gypsum granules derived from wasted gypsum boards are fed into the gypsum slurry from above. The gypsum slurry after mixing is made to flow to an outlet of the flow path while the upper surface of the gypsum slurry is always exposed to air. The gypsum slurry is fed into a pipe by free fall. The gypsum slurry is made to impinge on the far side of the pipe as viewed from the outlet and fall or to fall down the center portion of the pipe. The generation of gypsum scale is suppressed in the mixing device for mixing gypsum granules derived from wasted gypsum boards with gypsum slurry.
