Abstract
A concrete mixing apparatus including a paddle type mixer and a cement and water container mounted on a scale. The cement and water container is divided into separate cement and water compartments mounted above and upon the mixer to permit gravity flow of their contents through an open top portion of the mixer. Aggregate is supplied by a belt conveyor through a side opening. All ingredients are supplied by weight based on the indication of the scale. The scale includes load cells supporting the mixer. The arrangement provides flexibility in the manner of introduction of cement, water, and aggregate into the mixer.
