Abstract: A material handling system is provided having particular application in grey iron foundries. In general, the system provides a continuous flow of work from the time castings are removed from their molds until the castings are ready for shipping. In particular, the system includes an environmentally acceptable grinding room work station in the form of a totally enclosed work area. Means for feeding material into and from the work station include a first plurality of gravity feed input chutes operatively coupled to a conveyor system on the input side of the work station, and a second plurality of gravity feed output chutes leading to another area on the output side of the work station. The conveyor system is designed to carry the castings from shake-out to the enclosed work area. Scrap is separated from the molded parts prior to their entrance into the work area and rejected parts continue along past the gravity feed input chutes to an accumulation storage device.
