ABSTRACT:
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.
