Storage SilosKW - Flat Bottom Silos Features

The Kepler Weber line of flat bottom silos is designed to store grain (Wheat,Paddy Rice, Corn Maize, Soyabean, Canola & etc.) or free flow products with the specific weight of up to 0.83t/m³ or 0.60t/m³ in the case of the line of silos for rice. The storage capacities vary from 24 m³ (smallest model) to 18,268 m³ (largest model). This means storing between 18 metric tons to 13,701 metric tons of product or up to 228,000 bags, 60 kilograms each.

Operational Safety

Safety is a fundamental criterion for Kepler Weber and it permeates all the stages beginning with the project's conception all the way to the silo's manufacturing and use. During the phase of creating the project, a careful assessment is carried out on the types of actions during the operations of loading, unloading, and when the silo is empty. The silo also has warning signs posted at all entrances (ladders, doors, and inspection windows) and the ladders and platforms have baseboards, guards, railings, and cable clamps

Covering plates - Roof

The plates used as the silo's roof are made out of galvanized steel manufactured from rolled sheets with a trapezoidal shape and with a reinforced rim that has a different size than the interlocking plate in order to provide a perfect fit. Furthermore, the rim on the top plate has a flat surface in the region of support on the neoprene seal washer, making it highly water proof.

Side plates - Body of the Silo

They are produced using automatic sheet rolls with an undulated shape to ensure greater resistance to the assembled set, as well as standardizing the profile and drilling. The result is simple manufacturing and faster assembly time. The sheets are made out of highly resistant steel and coated on the surfaces with 99% pure zinc on a layer of 350 g/m².

Frame Posts

The frame posts are made out of high-resistant steel and have a "W" shape with reinforced edges and are made by means of a continual process of a fully automated sheet metal roller. The small thickness level and low weight facilitate assembly and transportation. The frame posts have the same shape on all parts, which ensures greater visual harmony for the silo. Some silo models have overlapping frame posts, which provide even greater resistance.

Vents

The vents have on the top seal part where they meet the roof an angular section in order to avoid the accumulation of husks and grains, which increases the useful life of the roof and makes it so that cleaning does not need to be so constant.

The roof plates were designed with a slanted and elevated flange fastened with a sealant that keeps out any type of water infiltration and results in greater rigidity for fastening it to the vent.

Roof Structure

It is made up of structural profiles joined by a single part, which gives it greater rigidity against any action done to the silo and a perfect assembly between the cross bars. This building design gives the roof greater resistance and minimizes the loads affecting it such as wind, thermometry, and catwalks.

Central Lid

Designed to give access to inside the silo for inspection and/or maintenance without the need to disassemble any loading equipment or ducts.

It also makes it possible to check the loading process.

Access doors

All the silo models have standard access doors located at the equipment's base in order to make it possible to get inside. This door has a more narrow side plate at the body, which is then assembled with other two complementary ones, allowing greater exchange and improving its looks from the outside.

Body Stairs - External and Internal

The external stairs have standard size rest platform, and guardrails. The internal stairs are equipped with cable clamps. They have been designed according to all the safety norms and requirements.

Ventilation Systems - Optional Accessory

Designed to provide ventilation of the grain mass by blowing air. It maintains the ideal temperature and humidity conditions of the grain mass stored and is turned on when the temperature raises, which is detected by the temperature gauge system.

The system has a centrifugal fan and a galvanized sheet covering with holes in it so that at least 22% is opened. The configuration of the coverage ensures homogenous distribution to the flow of air in the grain mass.

Side Spout - Optional Accessory

This makes it possible to remove the product from the silo's side without the need of any conveyor system. This solution brings greater savings when unloading since the product is unloaded directly into a truck.

The side spout can be folded back to allow vehicle access when not in use.

Grain Spreader - Optional Accessory

This device makes it possible to load the product more homogenously, reducing the concentration of impurities and broken grain in the silo's center. Two models are available:

* Motorized:
* Kinetic (gravitational)

Ladder on the roof with guardrail - Optional Accessory

The inclined ladder over the roof has skid-proof steps and tubular shaped handrails. It is used to access the top part of the silo, ensuring safety during inspection or when checking the grain transporter / spreader.

Circular Stairs - Optional Accessory

This is an option with silos larger than 36' and is used to access the silo's roof very quickly and safely. Its entire structure is made of galvanized steel and all of its steps from the silo's base are skid-proof, has a baseboard, handrails, and a rest platform (after the 13th ring).

Catwalks - Optional Acessory

These are made of ASTM-A572 G50 angle bars (caged catwalks) or out of high-resistant galvanized sheet metal in compliance with NBR 7008 (open catwalk) and is designed with a framed structure that is fully bolted together at assembly. The catwalks are designed to support the transportation of a load into the silo, service overloads, and strong winds, as well as to allow safe access to the silo's top.

The catwalk is supported by specific frame posts designed to resist the extra strain (its own weight, equipment, product transported, and wind). The walkway is made of anti-skid flooring and a baseboard and its tubular structure complies with safety norms.

Valves - Optional Accessory

The valves are used for unloading the silo and are located at their base (aligned in diameter). The valve turns the latch and provides an opening for the grain to discharge.

Sweep Auger - Optional Accessory

Auxiliary device for unloading the silo with a flat bottom. Its utilization is carried out at the end of the unloading process because the valves cannot remove the rest of the product.

It is available in the following diameters:
* Augers with chutes (low capacity):
- RV D130
- RV D180
* High-capacity augers (self-carrying):
- RD 200
- RD 250

Thermometry System - Optional Accessory

System in which cables with temperature sensors remain immersed in the grain mass and measure the temperature at different levels. With the Thermometry System readings it is possible to control the ventilation system to an adequate cooling of the grain mass.

Models available:
* Manual portable thermometry system
* Automatic portable thermometry system
* Computer thermometry system
* Automatic thermometry system
