FLAT-BOTTOMED SILO

Our silos are designed for storage of dry grain, rapeseed, maize, legumes and other loose materials. They are made of high-quality galvanized corrugated steel sheet made of S550GD grade steel, which increases the strength of the structure. Roofs of our silos are made of galvanized steel with MAGNELIS coating or galvanized steel additionally covered with a layer of Solano material, which ensures optimal protection and durability in particularly difficult weather conditions. It also provides corrosion protection class III DIN 5.5928.

Silos have two ventilation gaps enabling air exchange when loading and unloading. One of them is between the roof and the cylindrical part, the other between the roof and the roof cap. The ventilation gaps are protected by a cover that prevents the ingress of snow, birds and rodents. This cover is attached to the roof of the silo at a distance of approx. 3 cm from the silo cylindrical part.

The roof structures are calculated to withstand the increased snow load.

The shape of the roof supporting beams is designed in the form of gutters so that they can also be used to drain the condensate from the roof beyond the silo.

Our silos are distinguished by a number of technological solutions that increase their service life and further facilitate the grain storage process.

Standard equipment:

Optional equipment:

silo wall made of high quality S550GD steel, galvanized corrugated sheet
specially designed reinforced silo supports made of high quality S550GD steel characterized by increased strength
silo roof made of galvanized sheet additionally covered with SOLANO plastic, increasing resistance to weather conditions
roof structure calculated to withstand increased snow loads
patented condensate drainage system in the form of appropriately designed roof support beams so that they can also be used to drain condensate from the internal roof slope beyond the silo
efficient ventilation system in the form of ventilation gaps in the roof enabling air exchange during loading and unloading of the tank and a system of ventilation ducts in the silo foundation covered with optional gratings adjusted to the smallest grains, for which fans with high efficiency and high pressure are selected
ventilation gaps additionally secured with a cover preventing the ingress of snow, birds and rodents
service hatch in the roof slope
two-wing service hatch in the wall of the silo
high-class HILTI anchors for attaching the silo to the foundation

silo gallery for supporting the loading device with a catwalk along the conveyor and protective barriers
all kinds of sensors determining the conditions inside silo of filling the silo
temperature measurement system based on multi-sensor temperature probes arranged symmetrically in the silo
cascade filling consisting of a system of channels and cascades placed symmetrically on both sides of the silo, reducing the risk of crushing grain
side gravity discharge, allowing for quick emptying of the silo of grain located above the 8th ring
a system of galvanized ladders as well as resting and service platforms
stairs mounted on the silo wall to enter the service platform of the upper service hatch and the silo gallery
screw augers for final silo emptying, made with or without ATEX technology
properly selected outlet openings in silo floor with optional manually or automatically operated slides
service lighting for safe operation of devices, even after dusk

Types of foundations that we use:

Technology of emptying flat-bottomed silos:

This example shows the technology of emptying flat-bottomed silos on a elevated foundation with the use of a stationary screw auger.

The first step is to open the central slide and empty the silo until the hopper collapses.

The second step is to open the side discharge slides and empty the silo until the screw auger and service hatch are uncovered.

The third step is to start the screw selector walking around the silo axis until the silo is fully emptied.

The fourth step is to close the slides and turn off the devices.

Table of capacity and height of silos:

RIELA POLSKA silos marking method:

The first number (two-digit or one-digit number) indicates the designation of the silo series, which indicates the number of sheets that make up one silo ring. The second number (two-digit number) indicates the number of rings that make up the silo. For example, silo 408 is a 400 series silo with 08 rings, where one ring consists of 4 plates, silo 1223 is a 1200 series silo with 23 rings, where one ring consists of 12 plates.
