ABSTRACT:
An apparatus for continuously blending a viscous liquid, such as hot asphalt, with particulate solids, such as ground rubber, includes a vertical cylindrical tank in which is disposed a smaller vertical vessel defining therein a blending chamber. Open lower side regions of the vessel feed the blended slurry to a holding chamber defined between the vessel and tank. A shaft rotatably mounted through the blending chamber has fixed thereto a blending disc and two hollow blending cones coaxially mounted on opposite sides of the disc to form two shear-type blending regions. Hydraulically driven pumps and motors feed the viscous liquid and solids to the blending chamber, rotate the blender shaft and withdraw slurry from the holding region for use. Hydraulic flow control valves enable selectively variable feeding, blending and slurry discharge rates. The relative feed rates of the liquid and solids are preferably continuously monitored to assure the desired liquid/solid blend ratio. The apparatus may be mounted on a trailer or the like for ease of transportation.
