 Press Releases

  • Grain shipments require something special; their handling needs are like no other type of dry bulk material. The arrival of grain into ports is often dependent on harvests, volumes are not only dictated by demand, but also by the success of a crop’s season. Furthermore, the unpredictability of weather and ambient climate plays a major role from the field, to the port, and beyond.

    Grain handling operations are located in a variety of settings, from deep in the Amazon rainforest to bustling, inner-city ports. Often, systems have to be small enough to fit under protective canopies and light enough to be installed on floating pontoons or barges. Ship unloaders, loaders and conveyors have to adapt to locations, but the qualities needed for the successful handling of grains do not change.

    All-round excellence required

    These systems must be able to cope with intermittent, continuous or huge surges in demand, but not only this, they must also handle grain gently. This is because the rough treatment of grains produces powdery fragments, smaller than the grain particles themselves, known as fines. Fines can make the grain more difficult to aerate, increase spoilage rates and dust emissions, and their presence in high levels can mean that the quality of an entire grain shipment is downgraded. So, a once perfect grain can be turned to dust when not handled with care. It is also important not to spill or waste grain cargo as this not only negatively impacts the environment, but also the efficiency of the whole terminal  operation. Enclosed systems are therefore essential.

    Furthermore, flexibility is frequently required. Grain handling systems must often be able to accommodate a variety of agribulk all at the same high capacities and through-ship efficiencies. Selecting the right technology, therefore, against this backdrop of demands is critical, as it will deliver the highest profitability and the best return on investment for the terminal, and ensure the quality of grain shipments.

    Stand-out capabilities

    Bruks Siwertell is the only manufacturer of grain-unloading systems that can deliver a continuous rated capacity of up to 2,000t/h with minimal environmental impact, and handle grain gently enough that degradation and crushing are virtually eliminated. Unlike any other available technology, the Siwertell screw-type ship unloader can reach all corners of a vessel’s hold, as well as the areas underneath the hatch coamings. This delivers the highest possible through-ship efficiency, and significantly reduces the need for payloader input. This is a stand-out characteristic, as other systems can only operate within the area of the hatch opening, ultimately requiring substantial payloader assistance to empty a hold, which lowers overall through-ship efficiency.

    Our high-capacity systems are also more compact, lightweight and quieter than alternatives with equivalent rated capacities. This delivers benefits in terms of load-bearing requirements and lower investment costs for new jetties. The quiet nature of Siwertell units enables operations in very close proximity to populated areas.

    Furthermore, the Siwertell screw-type ship unloader can handle multiple materials such as soya beans, meals and other non-free flowing foodstuff without any loss of efficiency when switching between them. Large-scale units can, in fact, discharge a vessel without assistance from payloaders when unloading any non-free flowing material like soya beans or similar meal roducts. Again, unique Siwertell unloader capabilities.

    Bruks Siwertell’s grain handling excellence extends even further to conveying technologies. On the jetty, our high-capacity modular belt conveyors offer extremely efficient material handling. These jetty belt conveyors are coupled with a movable transfer trolley that connects the unloader or movable tripper car with a ship loader. The design of these accompanying technologies has been specifically developed to enhance the efficiency of grain handling on the jetty.

    For other conveying needs, for example from storage silos, operators can use our ground-breaking low-friction air-cushion conveyors such as, The Belt Conveyor™, which can deliver significant savings in maintenance and operational costs.

    Growing grain demands

    With the United Nations predicting that 83 million people are being added to global population figures every year, food demand is growing. It has never been so important to ensure that systems that handle world resources do so sustainably, efficiently and without waste. Investing in the right equipment is also a shrewd business choice. With our value calculation method, we can accurately simulate the impact of different technical solutions on the long-term profitability of an operator’s terminal. So, if you want a grain handling system that will deliver levels of profitability that you may not have even thought possible, why not get in touch?

    Some highlights from Bruks Siwertell’s grain handling portfolio include:

    Road-mobile unloaders

    For operators that receive grain at multiple locations or have terminals with minimal or no infrastructure we offer a range of Siwertell road-mobile unloaders. Based on screw conveyor technology, with a totally-enclosed conveying line for environmentally friendly, cost efficient operation, road-mobile unloaders are suitable for handling free-flowing dry bulk materials. Mounted on a semi-trailer, they are all fully road-mobile for transportation between ports and it takes one operative less than an hour to complete the unfolding operation once the unloader arrives on site. Packing away at the end of unloading is equally rapid. Siwertell road-mobile unloaders are available in three different sizes – the Siwertell 5 000 S, 10 000 S and 15 000 S – the largest offering a grain unloading capacity of up to 400t/h for ships up to 15,000 dwt.

    Port-mobile unloaders

    One of the latest additions to Bruks Siwertell’s market-leading portfolio of unloader products that serve the global grain industry is the port-mobile unloader. Optimized on many key levels from its stable, lightweight steel structure through to its gentle cargo handling, smooth cargo discharge, and total operational costs, the unloader offers full port mobility, excellent efficiency and rated capacities and reduced investment costs. The Siwertell port-mobile unloader uses a heavy-duty wheeled gantry with an advanced steering system and is available as a 400t/h or a 600t/h unit. It is an ideal solution for operators looking for a port-based system to discharge vessels up to 60,000 dwt.

    Large-scale unloaders

    Our range of large-scale Siwertell unloaders is divided into three main groups; the F-type, M-type and D-type.  Each is specified according to the size of ship to be handled, the rated unloading capacity required and the dry bulk commodity or commodities to be handled.

    The main difference between these types is the supporting steel structure carrying the conveyors on the arm system. The steel structures can accommodate a range of conveyor sizes and can be fabricated in various lengths to suit different ship sizes, up to 200,000 dwt.

    Siwertell unloaders have the ability to discharge non-free flowing materials like soya bean meal or similar meal products without assistance by payloaders. This multi-purpose function is unique to Bruks Siwertell.


    Bruks Siwertell’s market-leading ship loaders are based on screw, or belt conveying technologies and are delivered as stand-alone equipment or as part of terminal systems.

    Ship loaders are supplied as stationary or rail-traveling units with telescoping and slewing configurations. For even greater access to all parts of the hold, shuttling and slewing screw-type loaders can be supplied with a scissor-arm arrangement. We can deliver grain handling units with loading capacities as high as 2,000t/h.


    Our conveyor technology is designed to ensure that grain terminals can maintain efficient, smooth, flexible flows of bulk material from their intake and export arrangements, through to their storage facilities and reclamation systems and on to the ship unloaders and loaders on their jetties.

    We offer one of the most comprehensive ranges of conveyors on the market for handling grain. This includes technology from traditional belt and idler configurations and unique horizontal and vertical screw conveyors, to state-of-the-art, extremely efficient air-supported, low-friction systems such as The Belt Conveyor, which uses a patented pressurized air enclosure system.

  • Bruks Siwertell has recently completed the commissioning of a Siwertell ST 640-M ship unloader for Puertos Especializados Transnacionales PETRA’s (a subsidiary of Grupo Gramosa) new agri-bulk terminal in Veracruz, Mexico. From the outset, the import facility will be able to offer unmatched grain handling and environmental protection capabilities thanks to proven Siwertell screw-type conveying technology. 

    Originally ordered in 2018 and delivered fully assembled in 2019, the terminal is now complete and, following operator training, its new ship unloader has been brought online. Gramosa chose Siwertell technology because it out-performed all other competitor systems during a four-month selection process; particularly the two 600t/h pneumatic systems it was initially considering.

    The analysis showed that a single Siwertell ST 640-M ship unloader would be a more economical solution in the long run. The operating costs comparing two pneumatic unloaders, delivering an equal total capacity, was lower. Also, the Siwertell unloader offered cost savings from reduced berth occupancy as through-ship efficiency was greater. Furthermore, the quality of grain shipments was also considered. 

    “One of the many outstanding qualities of the Siwertell ship unloader is its ability to handle grains gently,” explains Per Wahlström, Contract Manager, Bruks Siwertell. “The screw-type conveyor offers steady conveying velocities, with minimal particle collisions within the conveyor, keeping material degradation to a minimum. 

    “But this was not all, the Siwertell unloader was selected after comparing many features such as operating principles and mechanisms, investment costs, as well as operating costs,” notes Wahlström. “In combination, the cost and energy savings, efficiency gains, and gentle grain handling, meant that Gramosa picked a Siwertell unloader instead. 

    “Its new owners are happy with the initial performance tests,” he adds. “In fact, the capacity of the unloader currently exceeds the capacity of the receiving equipment. So, the unloader is ready to offer more, should the terminal require it.

    “Gramosa can now expect the unloader to deliver long, reliable performance and easy dry bulk material handling; it is very well suited to the job it has been ordered for,” concludes Wahlström.

    The new, rail-mounted Siwertell ship unloader is totally enclosed, ensuring a spillage and dust-free operation. It has a continuous rated capacity of 1,200t/h and a peak one of 1,320t/h, discharging vessels up to 80,000 dwt. The unloader’s seamless flexibility enables it to handle a number of different grains such as corn, soya meal, dried distillers grains (DDG), and canola seeds without any loss of efficiency. 

  • Bruks Siwertell has won a service order for the total replacement of the electrical control system, including programmable logic controllers (PLCs), on one of two Siwertell 490-M type ship unloaders that serve the diversified agribulk company, Flour Mills of Nigeria, in Apapa Port, Lagos, Nigeria. 

    The unloaders, delivered in 2001 and 2007, are owned by Flour Mills of Nigeria. “They are very well maintained machines, and the owner and operator put a lot of emphasis on ensuring their peak condition,” explains Martin Sabel, Siwertell Electrical Surveyor, Bruks Siwertell. “This proactive approach to service meant that last year, we were approached by Flour Mills of Nigeria to initiate plans for the replacement of the electrical system on the 2007-delivered unloader, which is a refurbished machine, re-built to handle grain instead of cement. A follow-up visit revealed that the unloader’s existing PLC systems had become obsolete.”

    Both units have a rated capacity of 800t/h and are key machines, securing the import of grains for Lagos’ buoyant pasta manufacturing industry, which serves local and international markets. 

    “The two ship unloaders are still in good condition, after around 40,000 hours in operation, but exporting parts and support to this site in Nigeria can be a challenge with different regulations and long lead times. Therefore, forward-thinking when it comes to maintenance is a good strategy,” notes Sabel. “This is especially important as the unloaders ensure almost continuous pasta production.”

    The electrical control system upgrade will not only secure one unloader’s continued reliability and performance, but also, as any removed parts will be tested and kept as spares for use on the second unloader, the work maximizes its service life as well.

    “Flour Mills of Nigeria and Bruks Siwertell have a long-standing relationship, built on mutual trust and the knowledge that any work carried out is beneficial for both the customer and supplier,” says Sabel. “Some of the unloader’s components had become obsolete and hard to find on the market, so replacing the existing system with a new one, ensures many more successful years of operation, and the second unloader benefits from the spares.”

    By using genuine Siwertell parts and original equipment manufacturer (OEM) service, any new components seamlessly integrate into the existing system and functions, guaranteeing the very best performance. “A further advantage is that we are very familiar with the equipment and how it is used, which will add to the smooth conclusion of the project,” he adds.

    Bruks Siwertell estimates that the installation schedule is planned to be carried out towards the end of 2021. 

  • Grain handling can be a dusty business: ADM’s Ama facility left dust and spillage behind with the installation of enclosed ship loading systems from Bruks Siwertell; three years on and the site is setting new standards in efficiency and environmental protection

    A lot can happen in a year, and for one particular grain export site in Ama, Louisiana, USA, its ship loading and environmental protection capabilities were transformed. Owned and operated by one of the largest agribusinesses in the world, Archer Daniels Midland (ADM), in 2018 Bruks Siwertell completed the delivery and installation of three market-leading ship loaders.

    ADM prides itself on the adoption of technology that enhances its ability to connect agricultural crops to world markets. It has a global footprint, but a firm operational infrastructure in the US. Headquartered in Chicago, ADM’s domestic operations comprise more than 160 ingredient manufacturing facilities and more than 300 crop procurement facilities, located across 29 US states.

    Its scope includes grain elevators, ports and shipping terminals, which are used to store both raw agricultural materials and finished products. Many of ADM’s facilities are focused in the country’s major grain-producing states of Arkansas, Florida, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Michigan, Minnesota, Missouri, Montana, Nebraska, North Dakota, Ohio, Oklahoma, Oregon, South Dakota, Tennessee, Texas, Wisconsin, and Wyoming.

    A terminal in the spotlight

    ADM’s Ama, Louisiana, facility has been operational for decades and its equipment, which had once been fit-for-purpose, no longer was. “ADM recognized the need to replace its outdated and undersized ship loading technology,” explains Daniel Pace, Sales Manager, Bruks Siwertell.

    “The equipment had significant dust and spillage issues, as well as not meeting the company’s capacity needs,” continues Pace. “ADM wanted its ship loading system to be capable of accommodating post-Panamax sized vessels with enclosed conveyors, enclosed loading spouts and dust collection measures. Together these would provide the best possible dust control measures to protect the local environment.”

    ADM was a new customer, and approached Bruks Siwertell for a solution following good references and seeing its technology working well and benefiting other operators in the agribulk business, but also wider afield for handling a range of dry bulk materials.

    “We worked closely with ADM to establish its current needs, but we also considered the operational future of any installation, essentially to ensure long-term suitability and the potential capacity for growth as well,” he notes. “To maximize the efficiency of a terminal it is important to tailor it to fit operational profiles, but as bulk terminal equipment lasts for decades it is also essential to ensure that there is flexibility in the system for some degree of change.”

    Meeting customer needs

    “Our ability to provide turn-key, tailored terminal solutions that are specially designed to meet specific customer needs, was a critical factor in ADM making that final decision to adopt Bruks Siwertell technology,” explains Pace. “Our US presence, and local 24/7 support, were also extremely influential.”

    ADM’s ultimate solution for the Ama terminal included three pedestal-mounted, shuttling, slewing ship loaders with completely enclosed loading conveyors, along with six totally enclosed belt conveyors to feed dry bulk material to the ship loaders. For this particular system, the operator requested spacious access platforms for easy maintenance.

    The entire system was manufactured and pre-assembled into large, complete assemblies on the Harvey Canal and then carried on a barge to the terminal for final installation. It was commissioned in 2018 and has now been operational for almost three years.

    Each ship loader offers ADM a rated capacity of around 2,000t/h and can load post-Panamax sized vessels, up to 115,000 dwt and beam of 43m. They are in near-constant use and handle a broad range of grains including wheat, soya beans, milo, corn, meal, and dried distillers grains (DDGS).

    Ongoing operational success

    “The entire supply, installation and commissioning was undertaken in a year, and the results are impressive,” notes Pace. “ADM now has a system that offers completely enclosed dry bulk material handling, which not only eliminates waste from spillage, but crucially ensures that grain handling operations are dust free.

    “The entire terminal has been vastly improved and now, three years on, ADM’s experience of our equipment speaks for itself. The ship loaders and conveyors are part of a flagship installation, setting grain handling standards in the US, and month-on month, the Ama terminal continues sets new loading records,” he highlights.

    Advances offer sustainability

    As operators replace outdated equipment, it should not only meet a company’s capacity requirements, it should also enhance environmental protection.

    “We all have to be part of a sustainability drive, eliminating the unnecessary waste of cargo from spillage, and also protecting the environment from dust emissions. As dry bulk material handling equipment and technology advances, so too can our capabilities to significantly enhance the operational efficiency and sustainability of the terminals that rely on them.

    “We believe that ADM is one such operator; through its drive to improve the terminal equipment at Ama, the gains it achieved reached far beyond operational profitability, but have realized a wider accomplishment of significantly reducing its environmental impact as well,” Pace concludes.
