Mobile and cascadable storage silo

Abstract

A storage silo for storing granular material has a container supported by a base, the container having a roof and at least one side wall for defining a storage space beneath the roof. The storage silo includes: (a) a feed port for receiving the granular material at a feed-port height lower than the roof; (b) an auger for moving the granular material toward the roof within the storage space, the auger receiving the granular material via the feed port; and (c) first and second auger motors for cooperatively driving the auger, the first and second auger motors being disposed at opposing ends of the auger. A processor determines power levels for the first and second auger motors to minimize torsional strain on the auger. Granular material can be discharged from a first storage silo into a second storage silo positioned for cascading with the first storage silo.
