The material that holds the world together
Beckum, 19. July 2018

BEUMER Group supplies tailor-made solutions designed to make the production of cement more energy-efficient and eco-friendly:

Cement is the most commonly used building material worldwide and is continuously growing. Cement manufacturers are however faced with challenges: complying with ever stricter environmental regulations, in an industry with some of the highest carbon dioxide emissions. They are also faced with permanently increasing cost pressures due to excess capacities, especially from China. Many countries therefore import the material, instead of producing it. BEUMER Group supports cement manufacturers with systems and machines that are adapted to the market, increasing the efficiency of their systems and their competitiveness.

As the saying goes in the building industry: "Somewhere someone is always building something". Whether it is in North America, Asia or Africa: large infrastructure projects require more and more material for buildings, streets, airports, bridges or dams. Since 1990, global cement production has almost quadrupled. About 4.17 million tons were produced worldwide in 2016. This growth is mainly coming from the development of the Asian markets, especially China. Despite growing cement sales, cement manufacturers worldwide face production overcapacities that have been built up during recent years especially in China. This decreases global cement and clinker prices. Due to these overcapacities, some countries focused more on the export of cement and clinker, an intermediate product when producing cement. At the same time, an increasing number of countries decide to import cement or clinker, instead of producing it domestically. In 2016, more than 150 countries imported cement and clinker.

One of these countries is Australia. Brisbane for example, the metropolis on the Pacific coast, is one of the fastest growing cities on the continent. Its population of about 2 million inhabitants is expected to double by 2056. Construction sites all over the city centre are witness to this progress. Skyscrapers are springing like mushrooms. Due to their strict environmental regulations and price pressures, Australia imports an increasing part of their demand for cement and especially clinker. The clinker is imported and then ground down to cement in Australia. The imported materials are coming from multiple countries including Indonesia, China and Vietnam. The cement and clinker imports are increasingly replacing the local production. In 2016, the utilisation of the domestic cement production capacities was only at around 57 percent.

Reduce environmental impacts, increase energy efficiency

When producing cement large quantities of carbon dioxide is emitted worldwide. These emissions occur during various processes, but the majority comes from emitting the CO2 from the limestone used to produce cement clinker.

Depending on the processes used, the carbon dioxide emissions from producing cement are at 0.6 - 0.99 t of CO2 per ton of cement. The CO2 emissions from producing cement are estimated to account for seven to eight percent of the overall global carbon dioxide emissions. Manufacturers can reduce these large quantities for example by partially substituting the cement clinker with alternative materials such as fly ash, clay or granulated blast-furnace slag.

Another approach to sustainably reduce greenhouse gas emissions and production costs is to increase the use of alternative fuels for the cement production. The alternative fuels are used as sources of energy instead of fossil fuels like coal and gas. Besides liquid materials like waste oil or solvents, the majority of the solid alternative fuels are composed of municipal and industrial waste, such as plastic, paper, composite material or textile mixes. Whole or shredded waste tyres are also used and made up 6 % of the alternative fuels used in Germany for the production of cement in 2016. The calorific value of the rubber from waste tyres is comparable to that from hard coal, and the iron from the reinforcement can be incorporated mineralogically into the cement. This minimises the addition of ferrous corrective substances.

Systems adapted to the production

As a system supplier, BEUMER Group develops tailor-made solutions perfectly adapted to meet cement plant requirements: conveying systems such as troughed belt conveyors and pipe conveyors, different bucket elevator types and clinker transport systems, loading systems and complete packaging lines. BEUMER Group provides these solutions throughout the entire material flow chain from unloading the delivery vehicle to storing, taking samples, conveying and control feeding solid alternative fuels. BEUMER Group also provides fully automated systems that can control feed, singulate and convey large and heavy tyres to the inlet of the rotary kiln. BEUMER Group provides innovative intralogistic solutions to international cement companies who are looking for sustainable and cost-efficient ways to modernise their plants.

Aalborg Portland A/S relies on these solutions for example. BEUMER Group provided a complete solution so the cement manufacturer can recover energy from different types of waste at its plant in Denmark. Different types of alternative fuels are used in the calciner and in the main burner. These fuels are made of varying compositions and are efficiently stored, conveyed and fed. The customer received all equipment from one source, thus having only one contact.

The oven-ready alternative fuels are delivered in moving-floor trailers. They are unloaded and then temporarily stored at the receiving station. Both lines receive the transported material from the storehouse via the moving floors that have been modernised by BEUMER Group. To enable the transport of the pre-processed fuels from the storehouse to the calciner and to the main burner, BEUMER Group supplied and installed one Pipe Conveyor as the heart of this system. Using the Pipe Conveyor to transport the fuels is quiet and low-maintenance; and the enclosed system is also emission-free and energy-efficient. The enclosed construction prevents material from falling and dust and odours from escaping into the environment. With an ability to navigate curves, the Pipe Conveyor requires considerably less transfer points compared to other belt conveyors. This allows for substantial capital cost savings for the customer and BEUMER Group can customise the system to the individual routing.

Transport - low on energy and environmentally friendly

The BEUMER Group belt conveyors, Pipe Conveyors and open troughed belt conveyors, are particularly suited for transporting bulk material through rough terrain. The overland conveyors come with horizontal and vertical curves, depending on the topography, and can be over 10 kilometres long. Angles of inclination of up to 15 degrees are possible, depending on the characteristics of the material to be transported. The throughput capacity of BEUMER Group conveying systems can be up to 10,000 tons per hour.

Trucks are still frequently used for greater distances. Depending on the nature of the terrain, however, they can rapidly reach their limits as they require well-developed roads and fuel, for example. The costs arising for construction, maintenance and possible extension of these roads are not insignificant. In addition, all of this implies serious landscape changes. The emissions caused by truck traffic are high, both with regard to toxic substances and to noise and dust.

The BEUMER Group belt conveyors are provided with environmentally safe electric drives and low-energy belts. Therefore, especially in times of climate change and increasing greenhouse gas emissions they are considered a 'preferred option'. The motors - which, depending on the topography are run in motor-driven and regeneration mode - are mostly adjustable. This permits an optimum load distribution on the drive unit in different operating conditions. If the belt conveying system conveys downhill, the system works in generative operation. The generated electric energy is fed back into the public network by a regenerative feedback unit. This way the operating costs of the complete system can be further reduced.

Straight up

BEUMER Group provides different types of bucket elevators with low investment costs, a long service life and easy maintenance to ensure a cost-efficient production. The buckets are mounted either to a belt or a central chain, depending on the application. Thanks to consistent developments in the field of vertical conveying technology, BEUMER Group can provide each customer with the perfect solution, whether with belt or chain bucket elevators.

Until recently, the use of belt bucket elevators was generally limited to transporting fine bulk material, because there was a risk on the older models that coarse-grained bulk material could get stuck between the bucket and the belt and damage the belt. Through the consistent advancement of their belt bucket elevators, BEUMER Group developed the innovative high-capacity belt bucket elevator type HD (heavy duty), that makes it now possible to also efficiently transport coarse-grained material such as clinker. This bucket elevator designed to eliminate the space between the individual buckets and the belt. This prevents coarse material from getting stuck during the scooping and filling process and from damaging the belt. At the same time, it holds the same proven advantages of belt-based bucket elevators for the customer, such as the very high conveying capacity, prolonged service life of the belt and less noise generation. BEUMER is also well-positioned in the field of chain-based bucket elevators and its central chain bucket elevators offer highly-efficient technology for the vertical transport of coarse, hot or abrasive bulk material.


Until the final completion of cement in the silo, the greatest part of the costs is associated with the transport. Cement is transported in bulk and in bags. The majority of cement worldwide is loaded in bulk via terminals on road and rail vehicles or on ships. Another not insignificant part of the material is transported bagged, palletised and packaged and then transported to the customer, often over large distances. For this BEUMER Group provides entire packaging lines. They consist of the BEUMER fillpac R which operates according to the impeller filling principle. The weighing electronics make it unique. The product is filled according to the gross weight principle, i.e. the bags are weighed during the filling process. The weighing electronics of the system ensure exact filling degrees of the bags. The system is complemented by the BEUMER bag placer and a state-of-the-art ream magazine. The fully automatic BEUMER paletpac layer palletisers then stack the bags reliably with a capacity of 5,500 bags per hour. The systems can be equipped with a twin-belt turning device, so the bags can be turned to the required position fast, gently and without affecting their dimensions. Its intelligent control involves the dimensions and weights of the bags in order to achieve an exact positioning preset by the respective packing pattern. The finished bag stacks are then transported over roller conveyors to the BEUMER stretch hood A packaging system.

Loading and palletising in one

To further reduce the costs, the trend goes towards higher degrees of automation in the fields of packaging and loading, also on emerging markets like India for example. The goal is to reduce personnel, especially in emerging countries, where the transhipment of bagged bulk goods is increasing and labour costs are climbing. In order to fully automatically load the bagged bulk material on trucks, BEUMER Group offers the loading and palletising system BEUMER autopac, that can load up to 3000 bags per hour without any problems. The machine simultaneously loads and stacks bagged goods directly on trucks, pallets are not necessary. This system makes the loading of bags on trucks particularly efficient and cost-effective.  Using the BEUMER autopac can help save labour during the otherwise labour-intensive loading of cement bags. BEUMER products are also suitable for loading waggons and ships. BEUMER Group machines and systems help cement manufacturers worldwide to produce efficiently despite increasing cost pressure and strict environmental regulations.

Prepared for peak times
Beckum, 11. July 2018

Österreichische Post AG relies on new BEUMER Group high-capacity sorter:

Österreichische Post AG built its new distribution centre in Wernberg, in the southernmost Austrian state of Carinthia. Up to 30,000 packages are handled on a daily basis. The sortation system is at the heart of the logistics centre: it handles the sortation demands reliably and responds quickly during peak times. The BG Sorter is BEUMER Group's latest system development. It is powerful and energy-efficient yet runs so quietly that the working environment remains pleasant. The managers were also impressed by the trouble-free handling of the project.

Parcel shipping is growing worldwide, and Austria is no exception of course. One of the reasons for this growth is the enormous increase in online orders. Customers want their orders to arrive ideally on the same day, delivered right to their doorstep. Logistics and parcel services must be able to react accordingly to those demands, because the competition is fierce. The Austrian postal service has responded to this tough task and opened a new distribution centre in Wernberg, in the state of Carinthia. Put into operation in the summer of 2017, it distributes and delivers packages in Austria's southernmost state and East Tyrol. "The move to Wernberg was necessary, because the site in St. Magdalen no longer met our requirements," explains the new branch manager Kathrin Fischer. "The old distribution technology was no longer capable of handling the increasing volume and the hall was too small to install a new system." While the St. Magdalen site will remain operational for the distribution of letters, the most modern sortation and distribution system for packages, with a footprint of 5,000 square metres, is now operating for the Austrian postal service in a facility with 12,000 square metres of total space.

High technology, small footprint

The site is conveniently located between two big cities, Villach and Klagenfurt, easily accessible from the autobahn. On average, approximately 30,000 packages are handled per day, increasing to up to 50,000 during peak times such as leading up to Christmas. That means up to 6,000 packages per hour. "The various parcels must be handled with care and distributed quickly and accurately," said Fischer. The sortation system must meet these high demands. BEUMER Group provided the necessary technology, with its new high-capacity BG Sorter at its core, designed as a tilt tray sorter. "Our components have been installed, from goods receipt to goods issue," reports Frank Niemietz, Sales Manager Logistic Systems at BEUMER Group. Wernberg is a comparatively small site of the Austrian postal service. BEUMER Group had to install the entire system in the already existing hall with very little space.

BG Sorter: adjustable, quiet, reliable

When a truck docks at the hall for unloading, an employee places the packages on a horizontally and vertically adjustable telescopic belt conveyor. It transports the packages, which vary in shape and weight onto a BEUMER Parcel Belt Conveyor. The weight of each package is precisely calculated. The shipments are then dispatched onto the BG Sorter. The system can assign the parcels to the right destination because it is equipped with barcode recognition and with a laser system that continuously detects the parcel's volume and reports the result to the superordinate data processing system. If the packages cannot be read then they are sent to a special destination. An employee inspects and processes the parcels, then returns them to the BG Sorter.

"Our BG Sorter is based on tried-and-tested technologies," explains Frank Niemietz. "This includes the sorter frame made out of steel and the contactless energy supply instead of the typical contact lines, which are commonly used by the competition." The tilt tray sorter design is capable of conveying items of up to 60 kilograms. Wireless communication enables real-time data transmission, unlike infrared communication where data are transmitted only when an infrared sensor is passed. This reduces the communication time to milliseconds. "Different operating modes are also easily implemented. This allows us to respond better to sensitive products," explains Niemietz. "The items are discharged at different speeds and with high precision." Users can handle items of different sizes with more flexibility. "This machine allows us to handle a large mix of product with precision while being cost effective; and distribute to other logistics centres in Austria and our distribution units in Carinthia and East Tyrol," says Fischer.

Energy-efficient drive

The new BEUMER system is equipped with energy-efficient drives. The servo drive-based OptiDrive reduces power consumption and CO2 emissions. The contact pressure of the drive wheel is automatically set depending on the required driving power – even for braking, which makes this solution highly efficient and force-fitting. This boosts efficiency to up to 90 percent and enhances the service life of the drive wheels. The BG Sorter is equipped with carrying wheels that are larger than those used in comparable systems. They reduce the rotation frequency by 25 percent. This has a positive effect on the wear and tear and the noise. "One very important aspect for our 40 employees," says Fischer. "It stays very quiet in this hall, you can easily talk to each other, the operating volume remains very pleasant, which means it causes no additional stress for the employees."

The packages are transferred via chutes onto telescoping belt conveyors. The items are taken off the conveyors and transferred into swap bodies. They are then transferred onto trucks that carry them to one of the other six distribution centres in Austria.

Smooth project handling and reliable service

After the successful completion of the project, BEUMER Group continues servicing the customer. Österreichische Post has signed a hotline contract with BEUMER customer support. This allows the customer to contact a service engineer whenever necessary. If the machines come to a standstill, BEUMER Group can dial in directly to the machine via a VPN connection, examine the situation and solve the problem directly or come up with a solution together with the customer.

"This project was carried out extremely professionally and our communication with BEUMER was honest and direct the entire time," says Gert Haas, Technical Director at Österreichische Post AG, Region West. "We were able to stay on schedule and the entire system was commissioned on time. Quite extraordinary for a project of that size." Branch manager Kathrin Fischer is very satisfied. "The BG sorter operates very quietly, is highly reliable, and extremely precise and fast when it comes to sorting the products." And speed is a valuable asset in this industry, on top of the list for the customers. "We are the only parcel service in Austria that delivers six days a week, from Monday to Saturday," says Fischer.
