Abstract
An apparatus for delivering concrete to two spaced deposition points having a funnel-shaped hopper with a pair of outlets in the bottom which deposit concrete on conveyors. An inclined chute feeds concrete to the inner conical wall of the hopper as the chute rotates to minimize segregation of the concrete. Each outlet has a gate to control flow of the concrete to the conveyor beneath. To divert concrete from the hopper a side discharge chute is pivotally mounted in the conical wall of the hopper and can be tilted to receive concrete discharged from the inclined chute.
