Ghana: Denmark-based Investeringsfonden for Udviklingslande (IFU) and Norway-based Norfund have invested US$27.9m in CBI Ghana. The funding will support the cement producer’s upgrade of a clay calcination unit at its 0.6Mt/yr Tema grinding plant in Accra. Denmark-based FLSmidth is supplying the equipment for the project.

African cement producers have confirmed their interest in calcined clay over the last month with two new projects. The big one was announced last week when FLSmidth revealed that it had received an order from CBI Ghana. This follows the launch of a Limestone Calcined Clay (LC3) project in Malawi in mid-March 2022 in conjunction with Lafarge Cement Malawi.

FLSmidth says that its order includes the world’s largest gas suspension calciner system and a complete grinding station. The kit will be installed at CBI Ghana’s plant near Accra in the south of the country. The new clay calciner system is expected to substitute 30 - 40% of the clinker in the final product, resulting in a reduction of up to 40% CO₂/t of blended cement compared to Ordinary Portland Cement (OPC). Overall the equipment manufacturers reckon that the grinding plant will reduce its CO₂ emissions by 20% compared to its current output. There has been no indication of how much the order costs but CBI Ghana expects energy and fuel savings, as well as lower overheads from clinker imports.

The public announcement of the Ghana project was also foreshadowed by the visit of Professor Karen Scrivener to the Ghana Standards Authority in February 2022. This was significant because Scrivener is the head of the Laboratory of Construction Materials at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and has been one of the key instigators of the LC3 initiative since the early 2000s. Other calcined clay cements are available such as Futurecem or polysius activated clay (see below) but LC3 is arguably the most famous given its promotion in developing countries.

The Malawi project is at a much earlier stage. The government launched the public private partnership LC3 project in mid-March 2022 in conjunction with Lafarge Cement Malawi and Terrastone, a brick manufacturer. The Ministry of Mining is currently developing a memorandum of understanding with the Gesellschaft für Internationale Zusammenarbeit (GIZ), a Germany-based development agency. India-based Tara Engineering has also been linked to the scheme.

One thing to note about the Malawi project is that it is the first calcined clay project in the cement industry based in East Africa. All the other African ones are based in West Africa. The other two projects in this region are run by Turkey-based Oyak Çimento and its subsidiary Cimpor. The first of these is a 0.3Mt/yr calcined clay and a 2400t/day cement grinding production line that was commissioned in mid-2020. This plant is based at Abidjan in Ivory Coast. The second is a new plant that Germany-based ThyssenKrupp Industrial Solutions is building for Oyak Çimento at Kribi in Cameroon. This unit has a 720t/day calcined clay and a 2400t/day cement production capacity and it will use the supplier’s ‘polysius activated clay’ technology. ThyssenKrupp’s involvement came to light in early 2020 and commissioning was scheduled for late 2021. However, no update on the state of the project has been issued so far in 2022.

As the above examples show, Sub-Saharan Africa has at least one live calcined clay plant, two plants are being built and there’s one more at the development stage. This puts the region neck-and-neck with Europe, which has a similar mixture of current and developing projects. This column has been covering the wider trend of the growing usage of various types of blended cements recently, particularly in Europe and the US, with slag cements, Portland Limestone Cement (PLC) and more. With PLC, for example, note the transition of another two North American cement plants to PLC this week alone. As for calcined clay cement, it is fascinating to see the focus move to a different part of the world. Several commentators have predicted that the future looks set to be dominated by blended cements using whichever supplementary cementitious material (SCM) is most available for each plant. The growth in calcined clay confirms this view.

Ghana: FLSmidth has secured a contract for the supply of a clay calcination plant at CBI Ghana's 0.6Mt/yr Tema grinding plant in Accra. The supplier says that it will also install a complete grinding station to more than double the plant's production capacity. FLSmidth says that the entire project will reduce the Tema facility's CO₂ footprint by 20%. When commissioned, the new clay calcination plant will be the largest in the world, according to the supplier.

CBI Ghana chief executive officer Frédéric Albrecht said “Ghana is the perfect location for using clay as an environmentally friendly alternative to clinker. West Africa is traditionally a clinker and cement-importing region due to the lack of suitable limestone reserves. Developing countries with their young populations and a growing need for infrastructure and housing represent the future in cement consumption. Calcined clay cements are the most sustainable alternative to traditional clinker-based cement."

Denmark: The board of directors of FLSmidth has nominated current vice chairman Tom Knutzen as the new chair of the board and Mads Nipper as vice chair. Knutzen will succeed Vagn Sørensen as chair. Sørensen has decided to step down as chair of the board of FLSmidth since his election in 2011. He has decided not to seek re-election. Both nominations will be voted upon at the company’s annual general meeting in late March 2022.

Knutzen has been a member of FLSmidth’s board of directors since 2012 and is the current vice chair. He is also chair of the Audit Committee and a member of the Nomination and Compensation Committee. His career includes his current role as chief executive officer (CEO) of Jungbunzlauer Suisse, from which he has resigned effective end April 2022, CEO of Danisco, CEO of NKT Holding and non-executive board positions with Nordea Bank, Chr. Augustinus Fabrikker and Tivoli.

Nipper is the current CEO of the multinational power company Ørsted, which develops, constructs and operates offshore and onshore wind farms, solar farms, energy storage facilities, renewable hydrogen and green fuels facilities and bioenergy plants. He brings an international background to FLSmidth including renewable energy, energy efficiency, water management and water conservation. As a member of World Economic Forum's Alliance of CEO Climate Leaders, he leads the Power Working Group. He is also co-chair of the roundtable of hydrogen production under the European Clean Hydrogen Alliance and is vice chair of the international food company Danish Crown.

Russia: Eurocement has completed a Euro3.3m maintenance project on the kiln at its Mordovcement plant in Chamzinsky District. The wet-process kiln was reconstructed as part of a large-scale modernisation program. Work conducted included replacement casing bandages, roller supports, the kiln chain curtain and the welding of cracks along the kiln shell. The project included a major relining of refractory material with magnesia bricks produced by the Magnezit Group and aluminosilicate refractory bricks produced by BKO. Maintenance work was also carried out on the plant’s FLSmidth Cross-Bar cooler.

US: Ash Grove Cement has re-opened its Port Manatee terminal in Florida following the installation of a new Kovako type ship unloader supplied by FLSmidth. The machine was custom built for Ash Grove by the Denmark-based company to meet its specific needs. The cement producer says it is the largest mobile pneumatic ship unloader built, has twin 800hp blowers, 37m suction arm and can offload a dry bulk vessel at a high rate while maintaining maximum efficiency and minimising environmental impact by eliminating dust emissions.

A ribbon-cutting ceremony to celebrate the event was held on 7 February 2022 as a shipment of fly ash was processed at the site. This maiden shipment completes the Phase 1 transformation project at Port Manatee, which began in early 2021. The project is intended to improve the subsidiary of CRH’s capacity to import cement, slag and fly ash for customers in Florida and South Georgia. It is also planning to use the terminal’s existing silo capacity to complement the capabilities of Ash Grove’s cement plants in Sumterville and Branford.

India: Shree Cement has hired Denmark-based FLSmidth to carry out its digital transformation. The supplier will install its ECS/PlantDataManagement monitoring system at Shree Cement’s cement plants. It says that the technology will increase efficiency.

Shree Cement’s joint managing director Prashant Bangur said "We are always looking at ways to optimise production, and the decision to apply FLSmidth's information management system to all our sites is a natural next step." Whole-time managing director Prakash Narayan Chhangani said "FLSmidth is a trusted partner for us, as we demonstrated by the milling and pyro order we announced last year. And we are confident that this next step in our digital transformation will prove to be profitable."

Denmark: FLSmidth’s 2021 full-year sales were US$2.66bn, up by 6.8% year-on-year from US$2.99bn in 2020. The group had previously forecast sales of US$2.42 – 2.57bn in its guidance for the year. Its EBITA margin was 5.9%, in the upper end of the company’s guidance of 5 – 6%. The company said that the result included costs of acquiring Thyssenkrupp’s mining business.

Argentina: Welding Alloys Argentina has manufactured and delivered a key set of wear parts for the classifier section of an FLSmidth OK 36.4 type vertical roller mill installed at an unnamed cement plant. The parts were manufactured at a workshop in San Nicolás near Buenos Aires.

They included a new 5000mm diameter by 2760mm high fine separator section complete with full set of vanes. The section was manufactured in two halves for later assembly on the customer’s site with vanes made from 13 sheets of 6+4 Hardplate 100 and flanges from 16mm 450HB through hardened plate. Also included were the lower cone section manufactured from eight sheets of 8+6 Hardplate 100, the upper cone section from 11 sheets of 10+4 Hardplate 100 and the discharge tube manufactured from 8+5 Hardplate 100, all flanged with 450HB through hardened plate.

Peru: FLSmidth has secured a contract for the supply of a new pyro line for Cementos Pacasmayo’s Pacasmayo cement plant near Lima. The new line will give the plant an additional production capacity of 0.6Mt/yr. The supplier says that it plans to install a Cross-Bar cooler, low-NO_x calciner, Jetflex burner, equipment for dosing and feeding and process automation. FLSmidth says that the upgrade will reduce the plant’s energy consumption and open new opportunities for the use of alternative fuel (AF).

FLSmidth’s head of projects and upgrades and senior vice president Anders Josefsen said “We are very excited to work with Cementos Pacasmayo on this project – not only on growing the business, but doing it in a sustainable way. The new line will be equipped with a state-of-the-art pyro system including several of our MissionZero solutions. With this, Pacasmayo makes a significant investment in future-proofing its production.” He added “The Pacasmayo project is a prime example of our capabilities within process design: ensuring the integration to an existing plant, while also demonstrating our ability to deliver equipment that meets demands for energy and fuel efficiency.”
