Autonomous haulage in the cement sector
10 November 2021Volvo Autonomous Solutions and Holcim Switzerland announced this week that they are testing and developing the use of autonomous electric haulers in a limestone quarry. It’s a two-part project, as being able to run electric dump trucks will help Holcim to meet its sustainability goals by switching to renewable energy supplies. Automating the control of the trucks then lets Holcim work towards its digitisation targets as part of its ‘Plants of Tomorrow’ initiative. Holcim Switzerland has also been running a drone programme at the plant (see GCW520) and has been using a few electric concrete mixer trucks since early 2021.
The use of autonomous haulage systems (AHS) in quarries by the cement industry seems to mark the start of something new. As far as Global Cement Weekly can tell, the Volvo Autonomous Solutions - Holcim Switzerland project is the first one in the cement sector that has been announced publicly. Most of the examples of AHS to date have been for heavy mining applications such as iron ore, copper, oil sands and coal. Automation in limestone and aggregate extraction has been slower. One recent example in the aggregate sector was announced in late 2020 when Norway-based technology company Steer said it had signed a contract with Romarheim to supply three autonomous dump trucks for use in a stone quarry. Previously Steer has used its vehicles to clear unexploded ordinance for the Norwegian army.
AHS have been around commercially since the mid-2000s when Komatsu tested and then deployed one at a copper mine run by Codelco in Chile. By September 2021 Komatsu said it had commissioned over 400 trucks with its autonomous system and that these had hauled over 4Bnt of materials. For its part Caterpillar says it started its first automated vehicle research program in 1985 and was even testing a pair of Cat 773 dump trucks in the 1990s. However, it then took a pause before resuming after 2000 and starting its commercial projects in the 2010s. In April 2020 it hit 2Bnt of hauled materials by AHS using its MineStar Command product. Hitachi, Liebherr and Belaz have also been working on their own AHS products in conjunction with third party technology providers and these were developed later in the 2010s. Most of these products are complimentary control systems that have been added to existing models or can be added to new ones. Autonomous vehicle company ASI is the other big name in the field with its Mobius product. Unlike the other systems, this is purely a retrofit product. ASI does not make its own vehicles. Komatsu and Caterpillar have also developed retrofit kits for their systems.
Most of the products above look mostly like normal trucks with the addition of extra kit. Volvo and Scania have also been working on AHS but their products have been taking it further by removing the cab entirely. Scania launched its AXL product in September 2019. Volvo launched its Volvo Autonomous Solutions subsidiary in 2020 and its Tara system electric dump truck the same year. Volvo had previously planned to run a pilot for its Tara truck with Harsco Environmental carrying slag at the Ovako Steelworks in Hofors, Sweden. Unfortunately the pilot was disrupted by the start of the coronavirus pandemic shortly after it started.
It’s early days yet with the use of autonomous vehicles in the quarries of the cement and aggregates sectors. Obvious advantages are additional operational hours, better worker safety and reduced costs. As ever with automation, cutting out human jobs would be one disadvantage for the current workers at least. There is also the possibility that an experienced human driver using efficiency software tools might be better than a fully AHS. A challenge in the field is developing open standards or methods to allow autonomous machines to communicate or work with both products by the same manufacturer and its rivals, as well as with conventional human-driven ones. Another challenge is for the mining and quarrying industry to determine how flexible it wants its heavy vehicles to be. One thought to end with this that an autonomous vehicle with a cab and a steering wheel can still be driven by a human. The cab-less vehicles being tested by Volvo and Scania would be rather less useful if they get into a situation where the software can’t cope. Lots to consider.

Exclusion of Indian mining activities reduces cost of FLSmidth’s acquisition of ThyssenKrupp Mining to Euro280m
06 September 2021India: Denmark-based FLSmidth has agreed with Germany-based ThyssenKrupp to exclude the latter’s mining activities in India from the final deal in its acquisition of ThyssenKrupp Mining. This reduces the total cost of the transaction by 14% to Euro280m from Euro325m. FLSmidth said that the exclusion of the Indian business will not affect the transfer of its key intellectual property and technologies to the supplier as part of the overall transaction.
Australia/UK: InterGroup Mining has secured just under Euro60m from Luxembourg-based investment group GEM Global Yield as part of a share subscription facility. The Australia-based mining company says it will use the funds primarily for the ongoing development and commercialisation of its Brilliant Brumby kaolin and gold project in Queensland. The company hopes to sell the kaolin for use in cement and concrete production or as a feedstock for high purity alumina (HPA). It says it will be able to drawdown the funds over a 36-month term following a public listing of its common stock.
Neil Miller, the chairman of InterGroup said, “The GEM facility provides a major accelerator for InterGroup as we continue to prove up the scale of our Brilliant Brumby project and the optimal development path for the co-mining opportunity of kaolin and gold. It likewise enables us to continue our important research and development work into the new carbon reduction markets of potential scale that our minerals serve and which complement their existing known end markets.” InterGroup is currently working towards a potential stock market flotation in the second half of 2021.
Denmark/Germany: FLSmidth has agreed to buy ThyssenKrupp Industrial Solutions’ mining business (TK Mining) for Euro325m. FLSmidth says it hopes that the acquisition will allow it to create a global mining technology provider with operations from pit to plant. The purchase is also expected to benefit FLSmidth’s aftermarket business. The transaction is expected to complete in the second half of 2022 and it will be subject to approval by competition authorities.
TK Mining is a supplier of solutions for mining systems, material handling, mineral processing and services. It is present in 24 countries with engineering and global service centres, and has close to 3400 employees. In 2020 it reported sales of around Euro780m with around one-third deriving from services.
“TK Mining and FLSmidth are a perfect match, and I am proud to announce this agreement to join forces. This is a truly transformational deal allowing us to accelerate our growth ambitions in mining by creating a stronger talent pool and one of the world’s largest and strongest suppliers to the mining industry. Our complementary customer base and improved geographic coverage will offer a strong value proposition to our customers. There is a significant opportunity in transforming TK Mining towards FLSmidth’s business mix and model in which higher margin service business makes up about 60% of revenue. I look forward to welcoming TK Mining’s management team and talented staff to our organisation,” said Thomas Schulz, group chief executive officer of FLSmidth.
Australia: Fortescue Metals Group subsidiary Fortescue Future Industries has announced plans to enter green cement production. The company plans to make use of waste from green iron ore processing and ‘other easily-sourced materials’ in production.
Chief executive officer Elizabeth Gaines said “At Fortescue, we are leading the heavy industry battle against global warming, transitioning from being a major fossil fuel importer to a significant green and renewable energy and product exporter.” The group is targeting net-zero CO2 emissions by 2030.
India: The state government of Telangana has renewed The India Cements’ mining licence for two sites in Guntur district until 2037. These are the Pondugula and Pulipadu mines, which supply the company’s Vishnupuram cement plant in Nalgonda district. The Times of India has reported that the producer first received its licence for the mines in 2000 and applied for the recent extension a decade later.

This move supports FLSmidth’s ever-growing focus on customer service and aftermarket.”
ThyssenKrupp’s gambit
27 January 2021There have been two developments from ThyssenKrupp’s ongoing restructuring worth noting by the cement sector in recent weeks. The first is that the Germany-based engineering and steel producer has stopped trying to sell its cement plant division. The second is that Denmark-based FLSmidth is holding serious talks about buying its mining division.
ThyssenKrupp first announced plans for a major restructuring in mid-2019 with an anticipated reduction of 6000 jobs across the business. The sale of its elevator business for Euro17.2bn to private equity was announced in February 2020. Later in May 2020 it then revealed plans to divide its previous business areas into core, dual and multi track segments. Core - including Materials Services, Industrial Components (Forged Technologies and Bearings) and Automotive Technology – would be kept as before. Dual-track – including Steel and Marine – would either be kept as before or considered for consolidation. Multi-track - including cement plant engineering, mining and more – would be sold, added to a partnership or closed. By size, core reported sales of Euro16.1bn (53%) in the company’s 2019 - 2020 financial year, dual-track reported Euro8.8bn (29%) and multi-track reported Euro5.5bn (18%).
Volkmar Dinstuhl, formerly in charge of mergers and acquisitions, was put in charge of Multi-track. By October 2020 he was publicly admitting that the division was planning to “find a solution for all our businesses within the next two years” including cement plant engineering. In the same interview he described the Multi-track division as an internal private equity fund. However, the elevator business sale has been seen by several commentators as giving ThyssenKrupp more freedom around how to conduct its restructuring. Three months later and Handelsblatt, a German business newspaper, reported this week that ThyssenKrupp’s cement plant division may have avoided its multi-track fate. It cited internal communication to employees about what’s been happening with the sale. Principally, orders have picked up in the company’s new financial year, since October 2020, and although a sale has not been ruled out, it won’t be pursued until late 2021 at the earliest. This is potentially good news for the sector as a sign that the market may be improving and definitely good news for those employees working for the division.
As a competitor, FLSmidth would have been expected to be potentially interested in buying either ThyssenKrupp’s mining or cement plant division, or both. So, the only question was, when it made a point of saying publicly that it was in non-binding negotiations to buy mining, what about cement?
Looking at the numbers shows that FLSmidth’s mining division did better than its cement one in the first nine months of 2020 with order take up year-on-year and the mining industry described as being relatively resilient during the coronavirus crisis, with the majority of mines operational across regions. By contrast it pointed out that the cement market was still ‘severely’ impacted by the coronavirus pandemic and that future cement demand was dependent on general economic growth. Acquisition activity in mining certainly seems like the safer bet at the moment. Yet the temptation to neutralise a competitor may have been a strong one. With the mining deal still in progress and the cement sale possibly ended for now, we’ll just have to wait and see. Other buyers for both divisions are no doubt waiting in the wings should circumstances allow.
One final fun fact to consider is that the man put in charge of selling both of ThyssenKrupp’s mining and cement plant divisions, Volkmar Dinstuhl, just happens to be a World Chess Federation (FIDE) recognised International Master. Being good at chess doesn’t automatically confer skill at anything else. Just look at former world champion Gary Kasparov’s political ambitions in Russia for example. Yet, ThyssenKrupp’s elevator division sale has been seen as one of the largest leveraged European buyouts in recent years and has appeared to have bought it some time to mull its options over its cement plant division. With this in mind, any potential buyers for the rest of Multi-track may be wondering just how many moves ahead this seller is thinking.
