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.
