Grain Storage: Silo Inspection and Maintenance

grain storage

Like everything in life, steel silos also need to be maintained. A silo is a big investment and to ensure that the return on investment is worth its while, regular maintenance is of the utmost importance. We often see silos that are not maintained properly. Or not used correctly.

Do’s and Don’ts

  • Only use the silo for its intended purpose.
  • Make sure that your silo operator is well trained to use the silo.
  • Do regular inspections of your silo – internally and externally.
  • Recirculate the product on a regular basis – especially during long storage periods.
  • Do not overfill the silo.
  • Prevent mixing of different products in a silo. Contamination can be a big problem.
  • Check on the moisture content of the product to be stored.
  • Ensure that that product being stored is clean.
  • Inspect and maintain all equipment inside (such as sweep augers) and used for extraction (screw discharge and slide gates) prior to filling the silo with product.
  • Stay away from silos during thunder and lightning storms.
  • Do not make any unauthorized modifications to a silo.
  • After inspection, make sure the silo door is closed and locked prior to filing it with product.

Inspection and Maintenance

In the off-season and/or after the silo has been emptied, inspect the silo for the following:

  • Deformation of the silo.
  • Check for any form of corrosion – internally and externally.
  • If the silo is equipped with low and high-level switches, check the condition and functionality thereoff. 
  • Water ingress.
  • Inspect the silo foundation for any cracks.
  • Check the water proofing of the silo – silo to foundation.
  • Make sure the silos doors are functional and safe to use.
  • Check all silo vents for any form of obstruction such as bird’s nests, etc.
  • If the silo is equipped with extraction fans on the roof, check each fan if it is in a working condition.
  • Inspect the silo for any loose and/or missing bolts – inspection to be done internally and externally. 
  • The inspection of a silo aeration system (if the silo is equipped with such a system) if often neglected It is important to inspect and clean it. Cleaning it will ensure that the product gets aerated as required and prevent the infestation of bugs and the growth of mold. 
  • Check the functionality of the aeration fans.
  • Inspect and maintain all center wells and intermediate wells.
  • Inspect and maintain the sweep auger.
  • Inspect the earthing cables of the silo.
  • Inspect all access ladders and gantries. Repair if necessary.
  • Inspect all silo inlets for wear and tare
