Advanced silosystem through systematic development

Gruber smooth-wall indoor silos according to the EN1090 standard required by law

Smooth-wall indoor silos from Gruber are an effective solution for small to medium sized bins with capacity from 5 to 370 m³. The straight wall silos in standard are equipped with supports, feet and bottom mounting brackets.

Optional equipment:

  • entrance door
  • inlet for an auger
  • auger for discharge the silo
  • silo ventilation
  • covering net (bird net)
  • inside installation conus (optional with aeration)
  • discharge conus with feet (free standing)
  • base mounting ring.

The round grain bin consists of smooth (straight) and galvanized steel sheets, which brings lower dust amounts on the silo wall and low frictions during emptying. Strong thickness of the silo sheet metal (up to 1,5 mm) and outer stiffening frame ensure max. stability and thus longest life.

Easy flowing of the grain and no dust deposit because of smooth (straight) walls guarantee better storage quality. This prevents that conserved or moist grain solidifies in the silo.
