    摘要： 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.

    摘要： There is disclosed a technique for mixing concrete in which cement and aggregate are separately discharged from metering devices in free fall paths of precise predetermined cross-section toward a conveyor. The material paths converge toward a rotating mixing device positioned above the conveyor which intermingles the materials before they reach the conveyor. The conveyor includes an air supported endless belt equipped with adjustable wear strips for engaging the belt and limiting movement thereof away from the air support system. Means are provided to prevent belt damage caused by a prong of a mixing device binding a piece of aggregate against the belt.
