The roof of a silo: often overlooked, always essential
At Polem, everything revolves around the right flow. It starts with a strong foundation, but is equally determined by the top: the roof. It's one of the components we include in every design by default – and often adapt to the specific application. Where others see the roof as just a lid, we see it as an opportunity to eliminate risks and improve performance.That's why every Polem silo comes standard with a domed roof design. Not just for aesthetics, but because it's better in every respect. For safety. For durability. And for hygiene. Polem's pragmatic, confident approach ensures we deliver quality you can rely on.Why the roof mattersThe roof of a silo endures severe conditions:Overpressure during filling - Pressure can rapidly increase during pneumatic fillingUnderpressure during sudden product movement - When product collapses in the silo, it creates a suction force that strains the roofWeather influences such as wind, rain, and UV - Years of exposure to the elements places high demands on durabilityMechanical load from components - The roof must not only support itself but also the additional weight of equipment and installationsA poorly designed roof therefore poses risks. Think of deformation, lekkage, condensation, or even danger during explosions. Yet in many designs, it doesn't receive the attention it deserves. At Polem, we make the difference by giving it priority.Why Polem chooses a domed roofA domed roof – also known as a Klöpper design – distributes forces evenly across the entire surface. This makes it resistant to higher pressure differentials. Polem silos can standard withstand a P-red of 1.0 bar. For comparison: metal silos often top out at 0.5 bar or less.What does this mean for your business processes?Better explosion safety - For dust explosion hazardous products, the roof offers more resistanceSmaller and fewer explosion panels needed - Instead of using large areas in the silo wall, smaller panels in the roof will sufficeHigher capacity utilization - Because no explosion panels are needed in the silo wall, you can fill the silo to a higher levelSmarter with space and integrationOur roofs are not only stronger but also more intelligently integrated with all necessary components:Flanges for filling systems, filters, manholes, and measuring equipment are seamlessly laminated – eliminating additional risk of leakage or thermal bridges. This prevents condensation and product deterioration.Composite flanges instead of metal - Unlike competitors, we use fully composite flanges, which eliminates thermal bridges and guarantees better adhesion.Explosion panels are placed entirely on the roof. No flanges in the silo wall. This prevents stagnant product and increases hygiene, which is essential for food and pharmaceutical applications.Central filling connection - For even product distribution and to prevent tilting, we position the filling connection in the center of the roof.Benefits at a glance✅ Higher safety through better pressure resistance ✅ Less explosion surface area needed ✅ Better hygiene through smooth roof surface ✅ No thermal bridges or weak spots ✅ Optimal integration of all components ✅ More room for customized solutions ✅ Less maintenance due to durable construction ✅ Better utilization of your investmentThe difference between a silo and a Polem? It's in the roofAt Polem, we design each component as if it were crucial. Because it is. Since 1972, we've built a strong reputation in the Netherlands and beyond. We've seen cases where poorly placed filling connections led to tilting. Filters that clogged due to condensation from a poorly insulated roof. Explosion panels that didn't function properly due to obstructions in the environment.That's why we pay extra attention to the upper part of the silo. Because that's where safety begins.You build silos from bottom to top. But the top makes the differencePrecisely because we focus on the essentials, we know where Polem makes the difference. Our approach is pragmatic, challenging, and confident. We know that the roof design of a silo is not a side issue but a crucial factor for the safety, efficiency, and lifespan of your investment.Would you like to know what a good roof design can do for your specific situation? Or would you like an analysis of your current installation to assess whether it is safe and optimally designed? Our market specialists are happy to look at solutions that fit your business processes.It's not just storage. It's Polem. And the difference starts at the top.
The hopper makes the difference: why hopper design in silos is crucial
At first glance, a silo seems like a simple storage facility. But at Polem, we know that the hopper design forms the heart of an efficient and functional system. With over 50 years of experience, we have learned that the details in this design make the difference between a standard silo and a premium storage solution.More than just an exit pointThe hopper is much more than a simple discharge opening. It is an essential component that directly affects:The discharge quality of your productThe ability to completely empty the siloThe hygiene inside the siloThe lifespan of your investmentAt Polem, we design hoppers that perfectly match your specific application.Hopper angles for every applicationEach product behaves differently in a silo. That's why Polem offers hopper angles that optimize flow:Each product behaves differently in a silo. That's why Polem offers hopper angles that optimize flow:40° hopper angle: Ideal for food and feed applications such as sugar, salt, or starch. This angle ensures mass flow ('first in, first out'), essential for perishable products.60° hopper angle: Suitable for abrasive bulk goods such as fertilizer, cement, or lime. Core flow reduces friction and wear on the walls.Special angles (e.g., 30°): For unique products, we design custom angles tailored to your situation.The Polem difference: rounded transitionsA distinguishing feature of our silos is the smooth transition from hopper to cylinder. Unlike the sharp angles of metal silos, this offers:Better product flow: No build-up in corners, which improves hygiene - crucial for food and animal feed.Lower material stress: Less stress on the laminate allows for more efficient, stronger construction.Mass flow versus core flowWhen extracting bulk goods from silos, two main flow patterns emerge:Mass flow: The product moves as a whole through the silo, with the material that enters the silo first also exiting first (First in, first out). This is ideal for perishable products and prevents material buildup.Core flow: Here, a funnel-shaped channel forms in the middle while product along the walls remains stationary. This reduces wear but can lead to product aging and clumping in stationary zones.Solutions for difficult flowing products For products with poor flow properties, such as rice husk or bran, we combine:A hopper with the right angleA suitable vibrating bottomPossibly a deflector This integrated approach guarantees efficient flow, even with challenging materials.Prevention of segregationWith mixed products, such as animal feed, segregation is a risk. A well-designed hopper with mass flow keeps the composition consistent, which ensures product quality.Centric filling and emptyingFor optimal performance and safety, it is crucial that silos are always filled and emptied centrally. Decentralized filling or emptying can lead to slanting of the product, causing large, unevenly distributed forces on the silo and potentially creating dangerous situations.Customization for your situationNo two applications are the same. Our market specialists are happy to discuss with you to develop the ideal hopper solution, based on your product and processes.Investing in qualityA good hopper design is more than functionality – it's an investment in:Higher product quality through better flow and hygieneLower maintenance costs through reduced wearLess downtime due to reliabilityA longer life of your siloPolem expert checkFor existing silos, Polem offers the Expert Check. During this periodic inspection, our expert technicians check, among other things, the condition of the hopper and advise on any adjustments or maintenance. This helps you to ensure the optimal operation of your silo and extend its lifespan.Optimise your processesWould you like to know how the right hopper design can improve your production?

Precision storage in modern agriculture
The challenge: why storage is essentialIn today's agricultural sector, we at Polem understand that efficient storage is not a luxury but a necessity. Conversations with our agricultural customers reveal that the quality of storage systems directly impacts their business results. Moisture, product flow, and durability are challenges that many agricultural entrepreneurs face daily.What agricultural customers tell usIn our fifty years of experience developing storage solutions for the agricultural sector, we've learned a great deal from our customers. The problems they experienced with traditional steel silos – such as product clumping due to moisture and material remaining in corners and seams – have helped us better understand what's needed in the field.Experiences from poultry farmers: "Always perfect feed and no separation"Udo Baumeister and Stephan Werthmann, owners of Landwirt Baumeister in Breckerfeld, Germany, share their experience with our flat-bottom silos: "The flat-bottom silos are ideal; no separation and the feed always flows consistently.""We initially wondered if a flat-bottom silo would really make such a difference, but now we wouldn't want to be without it," says Baumeister. "When we heard about this silo from a colleague ten years ago, we already had several funnel silos from Polem. But I wasn't familiar with the flat-bottom. After positive reports from other poultry farmers and our feed supplier, we decided to take the plunge."The results proved convincing: "In the barn with the flat-bottom silo, we see higher laying percentages and better feed conversion compared to the two other barns with funnel silos. Our laying percentages are stable, the hens remain productive longer, and feed conversion has improved. We saw such a clear difference that we decided to replace our funnel silos with flat-bottom silos.""Very satisfied! No problems and easy to clean"Another experience comes from Rune Thomsen, manager of the Williamsborg estate in Denmark, a business with 110,000 broilers and more than 1,000 hectares of agricultural land where wheat, barley, rapeseed, and peas are grown."When we took over an outdated pig farm in 2015, we faced an enormous challenge," says Thomsen. "The old barns needed replacement, and we wanted to build a modern poultry farm with the best facilities. We chose Polem feed silos, and now – years later – we can say that we're still very satisfied with them."The Williamsborg estate uses six Polem silos: four 60 m³ and two 13 m³ for buffer storage. Thomsen particularly appreciates the hygienic aspects: "A major advantage is that the silos are easy to clean. We noticed this, for example, during a salmonella outbreak, when the cleaning process went smoothly."How different silo solutions address specific challenges1. Flat-bottom silos and quality preservationFor poultry farmers like Baumeister and Werthmann, the benefits of flat-bottom silos are concretely measurable:Continuous feed flow without interruptionsPrevention of separation of feed componentsFirst-in, first-out principle ensures that the oldest feed is used firstThe Air-Control system also ensures optimal temperature in the silo, preventing mold formation and feed quality loss. "This means less waste and stable nutritional value, regardless of weather conditions," says Baumeister.2. Hygiene and cleanabilityIn poultry farming, hygiene is a critical factor. Thomsen emphasizes: "The seamless construction prevents weak spots and keeps the feed in perfect condition. The silos are easy to clean, which proved crucial during a salmonella outbreak."This experience illustrates an important advantage of composite silos: due to the smooth surface and seamless construction, they are easy to clean and disinfect, reducing the risk of cross-contamination.3. Durability and ease of maintenanceThomsen appreciates the long-term benefits: "They are designed to last for years and remain in top condition, making our investment profitable in the long run. The combination of high-quality materials and thoughtful design ensures that we have experienced no problems with the storage or flow of the feed."Other customers also appreciate our composite construction primarily for:Absence of corrosion problems, even with aggressive fertilizersLong lifespan without visible degradation from UV radiationConsistent performance regardless of seasonal changesBaumeister confirms this: "The silos require minimal maintenance and ensure a constant feed quality, which is essential for the health and performance of our chickens."Automation and efficiencyModern agriculture demands efficient systems. Thomsen appreciates the advanced features: "The silos are equipped with automatic filling systems and sensors, allowing optimal management of our own grain buffer storage."Baumeister and Werthmann add: "Thanks to the right-angle transfer, the feed goes directly into the barn, without extra transfer points or sensors that could malfunction."These technical solutions directly contribute to operational efficiency:Fewer moving parts means fewer malfunctionsDirect transfer to the barn increases reliabilitySimple but effective systems reduce maintenance requirementsApplications for liquid product storageWith the brothers Hein and Lenus Waalkens, we've seen how the transition to composite tanks has led to what they describe as "reliable and solid storage of fertilizers." Their concrete experience aligns with what we hear from many agricultural customers.For liquid products, the choice of the right agitator proves essential. Our customers often start with standard 3 kW systems but sometimes switch to 4 kW HD agitators with increased service factor for more intensive use.The importance of maintenance and inspectionWhat we learn from our customers is the importance of regular maintenance. That's why we offer the Expert Check, where we work with customers to examine:The general condition of silos via an periodic inspectionEarly detection of potential problems to prevent costly damageAdvice on optimal use for specific applicationsWhy investing in quality storage pays offBased on customer feedback, we see that investments in high-quality storage systems pay off through:Reduced product lossesImproved product qualityLower maintenance costs in the long termFewer operational disruptionsAs Baumeister summarizes: "The flat-bottom silos from Polem have proven to be of tremendous value to our business. Our hens perform better, the feed is optimally utilized, and maintenance is minimal. It's an investment that more than pays for itself."Thomsen agrees: "The Polem silos offer our business not only convenience and reliability but also peace of mind. They contribute to efficient feed storage and an optimal living environment for our broilers."For each agricultural business, the specific benefits differ depending on what is stored and under what conditions. But the feedback we receive consistently confirms: the quality of storage directly influences the quality of the end product.For more information please check our website or contact us.

Composite vs. steel, aluminum, PP, PE and plastic silos and tanks
At Polem, we have been using high-quality composite materials since 1972 to create storage products that are seamless, strong, and mirror-smooth. In this blog, we dive deeper into the differences between composite and other materials for silos and tanks.What is composite?Composite is essentially a compound material consisting of two or more components with different physical or chemical properties. When these components are combined, a new material emerges with properties superior to those of the individual constituents.For Polem's silos and tanks, we use glass fiber reinforced plastic (GFRP), a specific type of composite. GFRP consists of:A polymer matrix (often polyester or epoxy resin)Reinforcement through glass fibersThis results in a material that combines the flexibility and design freedom of plastic with the structural strength of glass fibers.Composite versus other materialsGFRP (Glass Fiber Reinforced Plastic)GFRP is a specific type of composite. The term 'composite' is broader and can include other reinforcement materials, such as carbon fibers or aramid. At Polem, we use GFRP because of its excellent combination of strength, durability, and cost-effectiveness.PolyesterPolyester is often the resin matrix used in GFRP. It is therefore a component of the composite, not the composite itself. It serves as a binder for the glass fibers and provides chemical resistance.PP (Polypropylene) and PE (Polyethylene)These are thermoplastic polymers used without reinforcement for various applications. They are more flexible than composite but lack the structural strength and durability provided by glass fiber reinforcement.Steel and aluminumTraditionally, silos and tanks are often made of steel or aluminum. Although these materials are strong, they have significant disadvantages compared to composite:They are more susceptible to corrosionThey have poorer thermal insulationThey require welds and joints that can weakenThey have a rougher surface leading to more product adhesionThe advantages of composite for silos and tanks1. Seamless constructionOur composite silos and tanks are manufactured in one piece, without seams or welds that can leak or weaken. This results in hygienic storage where no product can accumulate in crevices or corners.2. Exceptional strengthDespite their relatively light weight, our composite structures are exceptionally strong and can safely store large quantities of material, even under demanding conditions.3. Mirror-smooth finishThe interior of our silos and tanks is mirror-smooth, which ensures:Better product flowMinimal product adhesionEasier cleaningImproved hygiene4. Corrosion resistanceUnlike metal alternatives, composite is virtually immune to corrosion, which significantly extends lifespan and reduces maintenance costs.5. Thermal insulationComposite naturally has excellent insulating properties. The insulation value of a tank or silo with 50 mm PU foam is comparable to that of a metal tank insulated with 100 mm rock wool and aluminum plating.6. Low maintenanceDue to its durability and resistance to both mechanical and chemical influences, composite products require less maintenance than conventional alternatives.Practical exampleIn the food industry, hygiene is crucial. The seamless finish of composite silos prevents product buildup in corners and crevices, which can cause mold formation and bacterial growth. Additionally, the mirror-smooth interior wall is ideal for products that are difficult to flow, such as powders and granulates that stick to rough surfaces.A customer in the dairy industry noticed a significant improvement in product flow and a reduction in cleaning time after switching from steel silos to composite. Additionally, the thermal insulation proved to be much better, leading to less condensation and better product quality.In the industrial sector, where many chemicals are used, the corrosion resistance of composite proves its value. While steel tanks regularly need maintenance or replacement due to degradation, composite tanks remain in perfect condition for years.FinallyThe choice of the right material for your silos and tanks directly influences the quality of your processes and end products. Composite offers clear advantages over traditional materials such as steel, aluminum, and unreinforced plastics.Every grain, every drop. Quality in, quality out.

The right flow: why composite silos are preferable
Quality in, quality outEvery grain, every drop. In the world of storage, everything revolves around reliability and quality. Choosing the right type of silo or tank not only determines how well your raw materials are protected, but also directly affects your production process and end result.Since 1972, Polem has been providing storage solutions that are distinguished by three essential properties: seamless, strong and mirror-smooth. Our composite silos and tanks are designed to optimally protect your raw materials and improve your processes.Why composite is the better choiceWhen choosing a material for silos and tanks, each type has its advantages and disadvantages. Yet we confidently choose composite for these reasons:1. Seamless constructionUnlike metal silos, where the transition from cylinder to hopper often presents a problematic edge, a Polem silo offers a smooth, rounded transition. This has two main advantages:Product flows better along the wall, preventing accumulation of materialHygiene problems such as mold and bacterial growth are significantly reduced 2. Mirror-smooth inner wallUnlike metal silos, where the transition from cylinder to hopper often presents a problematic edge, a Polem silo offers a smooth, rounded transition. This has two main advantages:Less chance of bridge formation or “rat-holingEasier and more efficient cleaningBetter hygiene, especially important for food and feed applications3. Optimal thermal insulationComposite silos protect your raw materials from temperature fluctuations and thus from moisture problems. The insulation value of a Polem silo with 50 mm of PU foam is comparable to that of a metal silo insulated with 100 mm of rock wool. This means:Less condensationProtection against extreme temperaturesLower maintenance costs4. Corrosion resistanceUnlike steel or aluminum silos, composite silos are virtually immune to corrosion. This results in:Longer life of your investmentConsistent product quality without contaminationSignificantly lower long-term maintenance costsThe science behind the right flowAt Polem, we use advanced flow profiles. Depending on your product, we choose a funnel angle of 40° (mass flow) or 60° (core flow). This choice is crucial for the optimal processing of your raw materials. For example, for food products such as sugar, salt and starch, we recommend a 40° hopper that provides “First in, First out” (FiFo) flow - essential for perishable products. For abrasive raw materials such as fertilizer or cement, a 60° hopper is often optimal, minimizing wear and ensuring longer life.It's not a silo or tank. It's a Polem.Our focus on quality is reflected in every aspect of our products. From the carefully chosen materials to the thoughtful design of each component.

The unique properties of composite keep your materials in optimal condition, without the risks of rust or moisture problems. Our silos are not only strong and durable, but also flexible in design. They can be customized to meet your specific storage needs, including unloading facilities and aeration systems. In addition, the smooth-finished interior walls reduce material accumulation, making cleaning easier and minimizing downtime.Seamless, strong and mirror smoothA key advantage of our composite silos is their seamless construction. At Polem, we strive to make the transition from hopper to cylinder as smooth as possible. This ensures improved product flow where activated carbon flows better along the wall, without accumulation in kinks or corners. This is essential for a product like activated carbon, which can easily accumulate in uneven areas due to its powdery structure. The mirror-smooth inner walls of our silos prevent activated carbon from adhering to the walls, resulting in optimal product flow and minimal material loss. In addition, this reduces the risk of dust accumulation, which can lead to self-ignition in activated carbon.Optimal protection against moistureFor activated carbon storage, moisture control is crucial. Moisture significantly reduces the adsorption capacity of activated carbon, which limits its effectiveness in filtration processes. Polem composite silos offer superior protection against moisture by:Thermal insulation: Composite naturally has insulating properties that minimize temperature fluctuations and prevent condensation.Air drying systems: Our silos can be equipped with advanced air dryers that regulate the moisture content in the silo.Seamless construction: No cold bridges or gaps where moisture can penetrate or condense.Safety firstThe storage of activated carbon poses specific safety risks, including the potential for dust explosions. Therefore, our silos can be equipped with:Explosion panels: Strategically placed to safely vent pressure in the event of a dust explosion.Pressure release systems: Prevent overpressure in the silo during filling and unloading.Advanced grounding systems: Safely dissipate static electricity, a major ignition source in dust explosions.Polem's convex silo roofs offer improved resistance to under- and overpressure and can be designed for a P-red of 1.0 bar, essential for the safe storage of dust-explosive products such as activated carbon.Durability and cost efficiencyIn addition to their functional benefits, composite silos contribute to more sustainable operations. Less maintenance and longer service life result in lower operating costs and reduced environmental impact. This makes them not only a practical, but also a responsible investment. By increasing the shelf life of your activated carbon thanks to optimal storage conditions, you also reduce the consumption of this valuable material. The efficient emptying of our silos ensures that minimal product is left behind, contributing to higher cost efficiency.Broad applicability in various industriesActivated carbon is used in a variety of industries.
