BEMA newsletter, March 2025

Life in a company is diverse. This also applies to BEMA, where since autumn, we have been busy with a range of internal tasks while also looking outward, developing, and expanding our customer portfolio.

We are pleased that you, our customers, entrust us with increasingly complex and comprehensive tasks. These require us to have a firm grasp on both development and production, ensuring that we maintain our sharp delivery times while delivering optimal solutions.

One major task since autumn has been integrating Anders Pedersen, Machine and Special Factory, with BEMA. We are now consolidating at our Haderslev site. We are almost ready, significantly increasing our production capacity. Among other developments, we have recently commissioned a larger lathe to supplement and expand BEMA’s existing turning department.

Bringing such a machine into the hall and simply turning on the power is not enough. A new floor and foundation must be cast, connections and ventilation channels established, and much more. However, our industrial technicians are now fully engaged in mastering the new machinery, enabling us to strengthen our production and, despite high demand, meet all expectations regarding delivery times and quality. Precision turning with tight tolerances is essential in our type of production and is crucial for both the manufacture of internal tools and final products.

One of BEMA’s owners, Erik Rasmussen, exemplifies the continuity that characterizes our company. He has now been with BEMA for 30 years. Erik Rasmussen has been a co-owner since 2006, and in 2021, he and CEO Jørgen Strøm acquired the entire share capital of BEMA, making them equal co-owners.

We extend our heartfelt congratulations to Erik on his anniversary, which will be marked internally.

At BEMA, we see a growing demand for complex and comprehensive screw conveyor solutions integrated into larger production plants. We take pride in this. In recent years, we have invested considerable resources in enhancing our ability to handle such projects, complementing our entire standard range of flights, screw rotors, and conveyors.

The food industry, in particular, demands specialized solutions. BEMA meets all the requirements expected of a supplier to the food sector, including a large stainless-steel production department. We are therefore a natural choice when developing solutions for food production.

A great example of our increasing engagement in the food sector is a specialized solution for a company where our system is an integral part of the manufacturing process. We have delivered a three-stage production line with three screw conveyors designed to occupy minimal space.

In the first screw conveyor, the raw material undergoes heat treatment while being transported to the next stage. The second screw conveyor cools the material using air. The third screw conveyor functions as a mixer, where various additives are incorporated, making the product ready for packaging. A small lifting screw then transports the product to subsequent processes and its final destination. All equipment is manufactured in compliance with the EC-1935/2004 food directive and made from acid-resistant stainless steel EN 1.4404 (AISI 316).

BEMA has developed the complete design of the screw conveyors in close collaboration with the customer. Each unit is tested before final assembly, ensuring that all components function correctly when they reach the customer’s site. By conducting a full test with power to the gearbox, we guarantee that everything operates as expected.

We frequently supply shaftless screws as part of specialized solutions. These spiral-shaped screws, without an inner core tube, are often used for transporting bulk materials that tend to stick, are viscous, fibrous, or otherwise difficult to move using a traditional screw conveyor.

These screws can both push and pull materials and are particularly useful in wastewater treatment, food processing, the chemical industry, and waste management.

Several advantages include:

BEMA newsletter, december 2024

We extend our sincere gratitude to our customers and business partners who have supported us throughout 2024. This year has witnessed significant growth and development at BEMA A/S, with heightened activity across our product lines, including augers, rotors, crushers, and bale openers. 

A notable milestone in 2024 was the acquisition of Anders Pedersen, Maskin- og Specialfabrik A/S in Barrit near Juelsminde, marking BEMA’s entry into the consolidation of the screw industry. This move is essential for addressing the increasing demands for technical expertise, a specialized sales force, and substantial investment to maintain our competitive edge. The acquisition opportunity arose as owner Arild Pedersen approaches retirement and seeks to ensure the company’s continuity under a new framework, creating a mutually beneficial scenario for both entities. 

We are in the process of merging our operations, with plans to consolidate all manufacturing at BEMA’s facility in Haderslev, which offers excellent prospects for ongoing growth and development. 

As we approach the festive season, we are focused on concluding this year’s activities successfully. On December 5th, we hosted a networking event that brought together almost 40 representatives from companies across Denmark. Concurrently, we celebrated the 20-year anniversary of businesses operating in the industrial area at Bredholm in Haderslev. Our decision to relocate to Bredholm remains strategic, with opportunities for further expansion in an area enriched with fruit trees and other valuable plantings. 

On behalf of everyone, we wish you a Merry Christmas and a prosperous New Year! 

We have developed a series of perforated screw flights for a client in the food industry, enabling the efficient separation of solid and liquid components during material transport. This auger solution is particularly effective for various food production processes, including the transport of raw materials, semi-finished products, and finished items, where solid elements must be separated from cooking broths or other liquids. 

The solution features a diameter of 1,230 mm, constructed from 1.4301/AISI-304 steel. The considerable diameter necessitates stringent material standards and precision; thus, we employed laser cutting to ensure optimal fit and functionality. 

This project exemplifies BEMA’s commitment to collaborating closely with our customers to create tailored solutions. The precise hole sizing in the design is crucial for the effective separation of solid and liquid materials, preventing clogs and ensuring operational efficiency. 

Our manufacturing process ensures that the components seamlessly integrate with the overall system, reducing assembly time, minimizing welding requirements, and facilitating rapid installation for quicker operational readiness. Additional specialized windings, such as conical designs or those featuring cutouts, can also be developed in partnership with our clients.

In the fishing industry, where frozen raw materials are commonplace, BEMA has recently delivered an auger solution that efficiently thaws frozen fish during transport. This system allows for the adjustment of thawing time using a frequency converter, ensuring that the fish reaches the desired temperature for subsequent processing. 

Perforated rotor flights facilitate the separation of liquids from the fish as it moves through the system. The scalable configuration of the augers, divided into sections, integrates seamlessly into the overall processing plant, enhancing operational efficiency. The outer diameter of the augers measures 2,000 mm, with a length of approximately 4.5 m. 

BEMA is certified to manufacture food industry equipment in accordance with the EU food directive, EC-1935/2004. The supplied augers are fabricated from 1.4301/AISI-304 steel and undergo acid treatment following welding to meet stringent food safety requirements. All welding is performed to ensure compliance with industry standards.

As the year concludes, we prepare for the Christmas holidays. BEMA will be closed from December 20, 2024, and will resume operations on January 6, 2025. To facilitate timely deliveries, the final order date is December 18, 2024. We encourage you to place orders as early as possible to avoid delays during the busy holiday period. 

BEMA newsletter, September 2024

The air is getting colder, the shadows sharper – and the fruit trees on the lawn in front of BEMA are starting to bear ripe fruit. All signs that autumn is upon us – and with that, the beginning of new, busy times. Join us for a tour of the news at BEMA and get an overview of where you can meet us at some of the autumn trade fairs.

We are proud to announce that we have just acquired one of our valued colleagues, Anders Pedersen Machine & Special Factory A/S (APMS). With this acquisition, we are creating the country’s largest company specializing in screw conveyor solutions for the industrial market.

The owner of APMS, Arild Pedersen, is approaching the retirement age and wished to transfer ownership of his business. Both he and we quickly recognized that joining forces would be an ideal solution. The screw conveyor industry is small and specialized, requiring significant resources for development and ensuring a modern production setup to meet the needs of even the most demanding industries. With this acquisition, we can streamline production and make optimal use of our combined expertise. This will allow us to create an even stronger platform for developing, manufacturing, and selling both components and complete screw conveyors to the broad industrial market.

Over the next 1 to 1½ years, we will consolidate development, sales, and production at BEMA in Haderslev, where we currently have 65 employees. In the meantime, APMS will continue its operations as usual with its 20 employees in Barrit near Juelsminde, with Arild remaining as director. He will also assist in the upcoming merger process.

We really enjoy attending the different trade fairs through out the year to meet new and existing customers, suppliers, and other partners. That is why we have planned a trade fair tour again this year, and we hope you will stop by our booths.

For one of our customers in Sweden, we have delivered a highly specialized solution that includes three stainless steel screw conveyors. Each screw is between four and five meters long and is designed to meet exceptionally stringent fire safety requirements. The screws will be used for transporting wood fibers, so it is crucial that neither sparks nor friction heat can arise, which could lead to flames or explosions in this flammable material.

The screws are made from AISI 316 steel. Notably, they must be ATEX-20 certified by an external inspection company such as the Danish Technological Institute and must comply with the requirements classified as ATEX zone 20 internally and zone 22 externally in the equipment. ATEX-20 is a regulatory requirement concerning classification and safety in areas where explosive atmospheres may exist.

This necessitates a high level of specialized knowledge and documentation from BEMA, and we are proud to have been selected among several local and international manufacturers.

We are in the process of implementing a new invoicing system, which will bring some changes to how invoices should be sent to us. We will, of course, provide more information directly to all suppliers once everything is up and running. However, we can already announce that a new email address for invoices will be established, and they should be sent as PDFs.

The system can automatically verify if our purchase orders match the invoices. If everything is in order, they will automatically proceed to bookkeeping and payment. In other cases, it will be easier to conduct checks, and the goal is to free up resources so we can become more efficient and increase our capacity, which we will likely need in the coming years.

While others take a break, our installers are hard at work. Everyone at BEMA is fully engaged after a well-deserved summer vacation—production is in full swing and buzzing with activity once again. However, we could not collectively take time off during the summer, as many of our customers often use this period for major renovations of their facilities. It’s often the only time production can be halted, allowing for new parts to be installed or replaced.

During the summer vacation, we dispatched three teams for five different assembly tasks in weeks 27, 28, and 29, both domestically and internationally. So, while customers are on break, we are on site ensuring that everything is ready for when they return.

BEMA Newsletter June 2024

Solar panels on the roofs of our production halls so we can produce our own energy. Electric cars for the sales team. And a wonderful outdoor environment where bees and flowers can thrive.

Does it sound like a fairytale from a distant future? It’s not! Here at BEMA, we have focused in recent years on how we can contribute to the green transition and improve the local environment. The latest initiative is that we will set up beehives on our grounds. We are talking to a local beekeeper about how to do this in the best way possible. In the meantime, we are ensuring that not only bees, but many other insects from butterflies to ladybugs, have something to live from: We are seeding wildflower seeds in the fields and have already planted more than 60 fruit trees and many berry bushes on the grounds in front of our administration building and canteen. The green lawns may be replaced by a more varied outdoor environment with high biodiversity.

BEMA produces in the hardest steel, but we care for the environment and want to help contribute to create a better environment for everyone.

With this little summer story, we at BEMA would like to wish you all a very happy summer. Soon it will be summer vacation for most, and we hope you have the opportunity to relax.

BEMA A/S will be closed for vacation in week 29 and 30, and in the week before (week 28) and the week after (week 31) we will operate with reduced staff. Please order wear parts and other items you know you might need well in advance.

We have just delivered a special solution to the food sector – a good example that innovation is possible even though BEMA is 77 years old. The years bring great experience, and when we combine the experience from all our loyal employees, there are no limits.

We are talking about a so-called malt loosener, which is used in a process where the product sometimes sticks together. When this happened, the material did not progress through the system. In close collaboration with the customer, we developed a solution with screw rotors that move up and down in the vessel through the material to loosen it. This way, the customer avoids production stops.

The best way to compare the solution is to a very large electric mixer with two Ø220 mm rotors as beaters – a good example of thinking outside the box.

No task is too small or too large for our skilled blacksmiths here at BEMA. We have just completed a ‘small’ project with just two screw rotors. On the other hand, they were over 46 meters long – divided into lengths of 22.5 meters and 23.5 meters, respectively.

Such a project takes up some space in our facilities but is not unusual for us. To ensure that the screws can deliver uninterrupted transport of the media they need to move, they are built in sections with hanging bearings.

Contact us if you need a similar transport solution for your upcoming project or have special ideas and needs. We strive to create security for all customers, and we will guide you all the way from the idea phase to the finished product.

When heat and power stations burn waste in their large facilities, it ends up as ash and slag. Sometimes unburned waste, such as styrofoam and microplastics, can pass through the furnace grates. Previously, all this was used, for example, as road fill, but today the rules are stricter, requiring unburned waste to be separated from the rest. 

Our development team got creative, and BEMA has designed a special screw that incorporates a form of water trap. The solution has just been installed in one of the large incineration plants in Denmark. A small transport screw forces the material down into a kind of water lock or water tank. Here it is cleaned and washed, after which it is caught by the solution’s second screw, which rotates in the opposite direction, and transported further to various outlets, so it is correctly sorted into relevant fractions. In addition to being used to wash the waste, the water tank also prevents fake air from returning to the incinerators.

The impressive part of this setup is that the two screws must deliver and transport the waste under a water surface and each in different directions. It is a difficult task to solve, as gravity will work against the desired way the waste should be driven forward –instead, all waste will naturally float upwards.

A solution like this places great demands on BEMA’s knowledge of screw conveyors, material flow, process knowledge, as well as the design and execution.

Contact Ronny Bæk at BEMA A/S if you want to know more about the solution that meets the latest requirements for sorting and treating slag and unburned waste.

BEMA newsletter, March 2024

At BEMA, stagnation is not in our vocabulary. We aim to keep evolving and improving. One notable trend in recent years has been the steady increase in the size and complexity of our projects, compared to our basic products. We take pride in the fact that both new and loyal customers choose us when they need solutions designed and produced, whether it is a standalone project or intergraded into larger systems.

In this newsletter, we will share a couple of these larger projects we have been working on.

To ensure efficient handling of tasks and consistently meet customer demands, we utilize the Stockmaster inventory management system. This system automatically alerts our suppliers and internal production system when inventory levels are low, ensuring that we always have the necessary supplies available. Additionally, Stockmaster will now encompass parts that have worn down in our lathe department, which helps creating a more streamlined production with complete control over all processes.

However, our focus extends beyond inventory management and production efficiency. Ensuring floor safety is equally vital for maintaining a secure workplace and meeting the high standards our customers expect. As part of our commitment to safety, we have participated in a research project focused on workplace health and safety. Following a thorough assessment, we achieved a score of 75 out of 100 points. While this is quite high, we have further improved our score by an impressive +10% throughout the duration of the project.

Many know our Sales and Product Manager, Ronny Bæk, from meetings, customer visits, and trade fairs. He has just reached a significant milestone at BEMA A/S – his 10-year anniversary, but he thankfully aims for at least ten more. We are thrilled because Ronny is not only highly competent and well-liked but also a key driver in the ongoing development of project sales and custom solutions here at BEMA A/S. We congratulate Ronny on his ten years at BEMA!

We have recently completed the production of a large pressure vessel, also known as a boiler, for one of our clients. This boiler will serve as the core component in a larger project solution. While the client provided the boiler design, we at BEMA A/S have handled the complete manufacturing process in accordance with all specifications and test requirements.

A crucial aspect of this project was third-party testing of welds and pressure equipment. Non-Destructive Testing (NDT) was conducted on all welds, and Pressure Equipment Directive (PED) tests were performed on the boiler’s pressure equipment. External certification serves as an additional assurance for the client, confirming that the work has been carried out to meet all requirements and specifications in the field. We went the extra mile by testing the boiler up to 24 bars, surpassing the minimum requirement of 18 bars.

For one of our clients abroad in the energy sector, we have produced no less than 14 conveyors with a diameter of 500 mm and 2 conveyors with a diameter of 600 mm. They are part of a large system for biogas production. The transportation screw conveyors vary in length – the shortest being 6,000 mm and the longest 13,600 mm. These conveyors transport the residual product from the biogas production across multiple levels to a final storage with six silos. From here, the farmer can retrieve the residual product, which is used as fertiliser.

The complete transportation screw system is designed to go around several pillars, along different floor levels, a staircase and in connection with walking decks, among other places. The system is divided into two parts, each with three storage silos, where our transportation also includes mixing screws, ensuring that the residual product is similar and can be immediately returned to the fields as fertiliser.

It has been a demanding design task, but the result is 16 custom-made screw conveyors that can be easily installed on site.

We have delivered screw flights to the other side of the world – 8975 km away, to be exact. Distance is not an obstacle for us, since we have recently dispatched a series of individually tailored crafted screw flight conveyors to a client in Honduras. This addition further enriches our already substantial international clientele.

The screw flights have been crafted from Hardox 450 and stainless steel 1.4301/AISI-304 and made with cut offs on the outer diameter. This requires a special design, showcasing our ability to tackle any winding challenge — even when the client is located on the opposite side of the globe.

In any BEMA transport solution, the most crucial component is the screw flights. For a screw rotor to fulfill its purpose, endure many hours of work, and require minimal maintenance, then the screw flight has to be precisely and perfectly crafted.

We have extensive experience in producing screw flights, covering all aspects from dimensioning to calculating pitch, thickness, inner diameter, and outer measurements. Our screw flights are manufactured through cold pressing, which guarantees optimal durability and strength. Even though it may sound simple, trust us, it is not that simple!

Our engineering department specialises in designing custom screw flights of any configuration, which gets tailored to fit the specific screw rotor. Precise screw flights save countless hours of adjustments during fabrication—and reduces costs! Therefore, we continuously strive to enhance our screw flight production to ensure they seamlessly fit when welded onto the core tube.

One of our specialties includes large screw flights measuring up to approximately a diameter of 2500 mm in Hardox and other abrasion resistant steel types. Here, we utilise sandwich plates that meet the demands of particularly abrasive applications. However, we also cater to smaller requirements if that is what you desire!

BEMA newsletter, December 2023

Thanks to the excellent cooperation with our numerous customers, at BEMA, we can look back on 2023 as a year where most of our business areas were in full swing. We have delivered many exciting projects in the auger transport of various materials. The rapid development of the recycling industry can also be seen at many of our customers’ sites. We are delivering increasingly more projects and transport solutions that are used for recycling customers’ materials or production waste, and we are also seeing increased demand for complete solutions for this. Thank you for the great cooperation in 2023!

This year’s trade show tour has now come to a close. Once again, many visitors stopped by our stands, and we held productive discussions about their needs and the possible solutions. In 2024, you will also see us at the most important trade fairs in the industry – it is going to be an exciting year too!

Like most companies, we have launched a number of initiatives to become a greener company and to achieve a smaller carbon footprint. We have installed solar cells on the roofs of our halls and they help cover as much of our daily electricity consumption as possible. However, now we also want to connect electric car charging stations to our solar panels. We are continuously replacing our fossil-fuelled cars with electric cars for our sales staff, and the first ones will soon be rolling out of the parking lot – charged with electricity we produce ourselves.

This summer, two apprentices passed their exams to become stainless steel mechanics. We have already signed four new apprenticeship contracts and we are in the process of signing another adult apprenticeship agreement. We would like to help train professionals for the industry and thereby help retain highly professional – not to mention exciting! – jobs.

We have delivered a true workhorse for the transport of plastic waste for use in the further processes of one of our customers. The solution consists of two 7,000 mm long rotors (Ø400) mounted in a steel housing. It is painted in the customer-specific RAL color. The auger flights are designed to pack down the transported material, thus making it more uniform for further processing.

To make the installation and maintenance as simple as possible, the rotor is made in two parts, and the solution is designed in a way to minimise ongoing service and maintenance beyond the natural replacement of wearing parts.

We have assisted the customer with capacity calculations for different rotor speeds in order to match the customer’s needs exactly. This is a great example of how we can leverage our engineering department to ensure the optimal design for a specific need. BEMA has the in-house capacity to assist with all the relevant engineering calculations when it comes to designing auger solutions and material transportation.

For one of our loyal customers, we have just installed a 9,000 mm auger, Ø350, which is mounted in a cylindrical housing that is 2/3 full of water when in working mode. The auger transports material mixed with water. In the top 1/3 of the housing, which is not water-filled, the water is drained off. The material then moves on to the processing stage. The auger system is made of 1.4404/AISI 316L stainless steel with an acid-resistant surface.

We developed the complete solution design together with the customer. They greatly benefitted from the fact that we have a full in-house engineering department and can perform all the calculations and drawings required.

Because we know our customer so well, we were able to design and manufacture all the components according to the location, making the installation work as efficient as possible.

The bottom of the auger housing has a plastic coating to provide the best possible support for the shaftless screw conveyor. In addition, we provided a walkway around the plant and equipped it with channels that guide the material to the inlet of the auger.

The end of the year is approaching, but before we start 2024, let’s enjoy Christmas and some nice days off until the New Year. At BEMA, we’re busy getting the last items finished and out the door before the holidays. We’re looking forward to keeping up the fast pace in 2024 and assisting you with exciting solutions and products that can best meet your individual needs.

We wish you all a Merry Christmas and a Happy New Year!

Holidays – closed days

BEMA A/S will be closed from 23 December 2023 to 1 January 2023, both days included. The last date for pickup is Wednesday, 20 December 2023 if the goods are meant to be shipped before the holidays.

At BEMA, we have 75 years of experience in the manufacture of all types of screw flights. It is a field that requires extensive knowledge, a sense of high quality and the utmost care in production.

Our construction department manufactures special flights which are made to fit the given auger rotor. The precision of our flights will save many hours of workshop adjustment during manufacture, thereby highly reducing costs!

That is why we are constantly working to further improve our manufacture of screw flights – to ensure an optimal fit when they are welded to the core housing.

One of our specialties is large flights of up to approx. Ø2500 in Hardox and other types of hardened steel. These are sandwich panels which are able to meet the requirements of particularly abrasive applications. At the other end of the spectrum, we sell small flights which are designed to solve specific tasks.
