ABSTRACT:
Loose bulk material, such as gravel or the like, is moved by a conveyor or the like from an initial station to a storage area or to a final station where it is utilized in some manner, such as being mixed with other material. When the level of the loose bulk material at the final station is at a maximum level, any loose bulk material coming from the initial station will be conveyed to the storage area where it will be stacked into a storage pile having a predefined shape. When the level of loose bulk material at the final station drops to or below a minimum level, any loose bulk material coming from the initial station will be conveyed directly to the final station. In addition, loose bulk material will be reclaimed from the storage pile in a predefined pattern so as to leave any remainder of the storage pile in a portion of the predefined shape. Once the level of loose bulk material at the final station again reaches the maximum level, any loose bulk material coming from the initial station will be again conveyed to the storage area and stacked onto any remainder of the storage pile in a predefined pattern to restack at least a portion of any remainder of the storage pile in the predefined shape.
