There are a wide range of Storage Silos available. The types of storage silo includes.
- Hopper bottom silos
- Flat bottom silos
- Square bins
A number of manufacturers of Hopper bottom silos are capable of designing, manufacturing and installing. Silo design should be based upon the pressures and loads derived from either the German DIN 1055 1987 or Eurocode 1 part 4 with structural calculations based on BS 5950 part 5 or Eurocode 3.
Typical hopper bottom silos range from three metre diameter offering fifteen tonnes storage to ten metre diameter often one thousand seven hundred tonnes. Choose only hoppers that are designed for high cyclic loading, e.g. frequent usage of product fill and empty at large tonnage rates. Typical standard hopper angles are forty five degrees and sixty degrees hoppers though other hopper angles are available. For construction silo roof panels, silo wall sheets and stiffening struts (up to three mm thick) are cut and fabricated from a minimum of G600 galvanised steel sheets. Typically stiffening struts (which should be thicker than three mm) are cut and fabricated from black steel and hot-dip galvanised for protection.
Storage Silos Supplier Considerations
When identifying storage silos suppliers choose a manufacturer who can design and manufacture at a single site. The benefit of having a manufacturer with these capabilities is that they can manufacture non–standard silos and hoppers.
An advantage of hopper silos is that they can provide temporary wet grain storage as part of a grain drying process. Additionally they can be used as “buffer bin” applications in silo plants. Possible applications include
- Storage of other free flowing granulated products,
- Feed pellets and wood pellets in relevant industrial plants.
- Where a faster discharge of larger batches of grain are required (typically sea and river ports, breweries, malting, mills).
