Silo Support Configuration

The base of a silo is typically constructed in one of three arrangements:

  • Fully skirted, with a full-height silo wall covering an elevated hopper outlet;

  • Short skirt, in which the silo wall extends a few feet below the top of the hopper for connection to a support structure;

  • Flat bottom, with an auger or other reclaim equipment at the bottom of the silo.

Cone-Bottom Silos

Cone-bottom metal silos are used to store various types of materials, including grain, sand, salt, cement, and powder. Cone-bottom silos can be constructed on structural steel supports to facilitate loading materials for transport, and are typically used for temporary storage during trans-loading.

Horizontal Silos

Best suited for temporary storage, horizontal metal silos can be portable, and are used to store cement, lime, fly ash, sand, metal chips, or powdered waste as part of mobile construction sites or air filtration. When installed permanently, horizontal metal silos are installed on structural steel supports to allow gravity-fed unloading.

Flat-Bottom Silos

Typically installed at ground-level, flat bottomed metal storage silos can be used to store materials for long periods of time. These large metal silos normally use stiffening rings to protect from wind buckling.
