Abstract
A conventional tower silo is converted to a limited oxygen feed storing silo with the use of an air impervious liner and a floor supporting a bottom unloader. The liner has plastic liner sheets attached to the inside surface of the silo side wall with fasteners, as adhesives and nut and bolt assemblies. An alternate liner comprising a tubular air impervious plastic member is located within the silo. The plastic member is not attached to the silo side wall. Supports mounted on the silo side wall under the roof carry the upper end of the liner. In one form, a plurality of springs connected to the supports and liner yieldably support the upper end of the liner in the silo. In another form, the upper end of the liner is yieldably supported with a plurality of counterweights connected to the liner with cables. An inside wall surrounding base aggregate supports the floor independently of the silo side wall. The floor has a radial trough accommodating the bottom unloader.
