Abstract
A method and system for handling granular material, such as proppant used in hydraulic fracturing in well drilling, is provided. In an operational configuration, a delivery module having conveyors receives and conveys granular material to a delivery location, and one or more mobile storage modules receive, hold and dispense granular material downward to the delivery module. The mobile storage modules comprise a raised, angular container portion for holding granular material. Each module may comprise a rock-over chassis for support against ground. In a transportation configuration, each of the delivery modules and mobile storage modules are separately transportable as semi-trailers. System redundancy features such as hydraulic power packs are also provided for.
