Pakistan: Germany-based Menzel Elektromotoren has revealed work on a replacement motor it has built for an unnamed cement plant in Pakistan. As part of the project it has designed a motor to fit a limited installation space that could drive the unit’s raw mill, another cement mill or a fan.
The engineering company’s solution was a compact slip ring motor in frame size 710 with the cooling system tailored to fit around a steel girder in the cement plant. To accommodate the existing couplings in two different sizes, Menzel designed the replacement motor with two shaft ends with different diameters. The motor output is configured to ensure efficient continuous operation in each of the three applications. The machine has a rated output of 4600kW and a rated voltage of 6300V. It complies with protection class IP55. At the customer's request, it was designed in cooling type IC 666, with permanent external ventilation of the inner and outer cooling circuit. Before delivery, Menzel also ran a load test in its in-house test field with the end-user attending via video streaming.
Ssangyong Cement orders equipment from KHD for Donghae plant
31 August 2022South Korea: Ssangyong Cement has ordered equipment from Germany-based KHD Humboldt Wedag as part of an upgrade to clinker production line five of the Donghae plant. The scope of supply for the contract includes: a Pyroclon R type calciner with Pyrotop mixing chamber; a Pyrorotor type alternative fuel combustion reactor; a Pyrobox type coal firing system for process start-up and operation balancing; replacement of stage four cyclones with new high-efficiency cyclones for calciner connection and an overall pressure drop reduction; a new kiln inlet chamber with orifice, kiln hood and tertiary air ducts; and a new Pyrofloor PFC 738AW type cooler with a Pyrocrusher PRC 420-4ES.
This project will be the fourth Pyrorotor installation at the Donghae plant. KHD’s scope includes the engineering and supply of mechanical equipment for the clinker production as well as electrical equipment for the overall modernisation of the production process. The project scope is the same as the modernisation contract of line four of Donghae plant, which was signed in February 2021 and currently is in commissioning. The commissioning of the modernised line five is scheduled for the fourth quarter of 2023.
India: UltraTech Cement has commissioned a 1.3Mt/yr upgrade at its Dalla plant in Uttar Pradesh. Following the work the plant now has a total cement production capacity of 1.8Mt/yr. The cement producer said that the project was the first part of a capacity expansion drive previously announced in late 2020. It added that with this latest upgrade its total cement production capacity in India is just under 116Mt/yr.
Cemex to expand Rockfort cement plant in Jamaica
30 August 2022Jamaica: Mexico-based Cemex plans to expand production by up to 30% at its integrated Rockfort cement plant near Kingston. The first phase of the upgrade project will cost around US$40m and be completed during 2024. Cemex’s chief executive officer Fernando A Gonzalez made the announcement during a visit to the plant. Andrew Holness, the Prime Minister of Jamaica, also attended the event.
Gonzalez said “We are in the final stages of the engineering phase and in obtaining permits from the local authorities.” He added, “Very soon we will begin to procure the equipment needed for this initial phase of the project, designed to not only expand our capacity, but also allow us to optimise our heat consumption in the manufacturing process, and therefore, reduce the carbon footprint of our cement facility in Jamaica.”
The event also included the unveiling of a mural at the plant which commemorates the 60th anniversary of Jamaica’s independence. Titled ‘Reignited for Unity’, the mural measures around 15m tall by 50m wide. It was painted by Mexican artists Irving Cano and Freddie Herrera and Jamaican artists Anthony Smith, Yanque Yip and Jordan Harrison. The mural is part of a local government initiative to use art to promote different communities in Kingston.
Dominican Republic: Cemex says it is planning to start using hydrogen technology at its integrated San Pedro De Macoris cement plant. It inaugurated the project during a visit by chief executive officer Fernando A Gonzalez. It is part of the company's Future in Action program that seeks to achieve carbon neutrality by 2050.
The group currently uses the technology by injecting hydrogen into cement plant kilns to optimise the combustion process and to increase the use of alternative fuels. It ran a trial at its Alicante cement plant in Spain using hydrogen in 2019 and says it rolled the process out to all of its European cement plants in 2021. Other hydrogen-based projects the cement producer is working on include a partnership with Hiiroc, a gas-to-hydrogen plant producer, and the creation of a renewable hydrogen industrial plant in Spain in collaboration with Acciona and Enagas.
Halla Cement awards upgrade project to KHD
30 August 2022South Korea: Halla Cement has awarded a supply and engineering contract to Germany-based KHD Humboldt Wedag for an upgrade of line 2 at Okke plant. KHD will supply a new Pyroclon R type calciner, with a Pyrotop type mixing chamber, and a 4.2m x 15m Pyrorotor type combustion reactor. Other equipment being provided includes: a Pyrobox type coal firing system for process start-up and operation balancing; replacement of stage five cyclones with new high-efficiency cyclones; and a new kiln inlet chamber with orifice. Erection and commissioning of the modernised production line is scheduled for the first quarter of 2024.
This latest project marks the second installation of a Pyrorotor at Halla Cement’s Okke plant. The installation of line 3 at the site is currently ongoing with commissioning scheduled for the first quarter of 2023. Overall, this will be KHD’s ninth installation of a Pyrorotor in South Korea.
The Pyrorotor has been promoted to cement plants as a way of using low-quality alternative fuels with minimal pre-processing. It offers a thermal substitution rate of over 85% and will also allow the Okke plant to reduce its NOx emissions. The installation of the new Pyroclon R type calciner and the high-efficiency cyclones in the lowest preheater stages will also provide the production line with an increase in efficiency due to an overall pressure drop reduction in the entire preheater.
Fuel costs in India, August 2022
17 August 2022Fuels procurement and costs have been weighing on the minds of Indian cement producers since the start of the Russian invasion of Ukraine in February 2022. Two news stories this week show some of this. The first concerns recent imports of petcoke from Venezuela. The second covers the closure of captive power plants due to domestic shortages of coal.
At the same time, as the financial results for cement companies for the first quarter of the Indian 2023 financial year have been released, one constant has been hefty hikes in power and fuel costs. Graph 1 below gives a rough idea of the jump in costs major producers have been contending with. One point to note is that, possibly, the larger cement companies may have been better at slowing down the cost inflation from fuel. However, the prevalence of waste heat recovery installations and alternative fuels usage may also be a factor here. Finally, the company approved to buy Ambuja Cement and ACC, Adani Group, also runs India’s biggest coal trader. It will be interesting to see in the medium term how this might affect the fuel costs for its new cement division.

The Venezuelan story demonstrates the greater lengths that Indian cement producers are now going to secure fuel supplies. Reuters reports that cement companies imported at least 160,000t of petcoke from the South American country between April and June 2022 and that more was on the way. JSW Cement, Ramco Cements and Orient Cement are among them. The Venezuelan oil industry has been under US economic sanctions since 2019 but byproducts such as petcoke are not covered by this. Its petcoke has apparently been discounted by 5 - 10% below the price of US alternatives.
Indian cement producers have been prepared to risk US sanctions further by importing coal from Russia. The Business Standard newspaper, using data from Coalmint, reported that Russia became India’s third largest source of coal imports, at 2.06Mt, in July 2022. Before the war it was the sixth-largest source of coal to the country. Again, Reuters covered how cement companies were doing this in July 2022, when it revealed that UltraTech Cement had used India-based HDFC Bank to purchase coal using Chinese Renminbi, not the US Dollar as is more common for international purchases of commodities. In a conference call for the release of its first quarter results, UltraTech Cement’s chief financial officer Atul Daga confirmed the purchase and described it as “opportunistic.” He added that, “If something more surfaces, we will pick it up.” As the data for July 2022 shows, it may or may not be UltraTech Cement that is buying Russian coal right now but other parties in India certainly are.
Some of the wider economic implications about India buying Russian coal in the face of US and European sanctions include whether any retaliation might be forthcoming and a general sign that the dominance of the US Dollar as the world’s reserve currency is not guaranteed. The former seems doubtful given the size of India’s markets. Yet if the sanctions against Russia drag on then a shift in the global economic status quo becomes more likely, especially if opportunistic purchases become regular ones.
The situation facing captive power plants illustrates one more turn of the screw on energy costs for industrial manufacturers. 30% of captive power plants in India are reportedly closed due to the high cost of coal or an inability to even import it. Although it is worth noting that it is unclear whether, proportionally, more or less of these are serving cement plants. As N Srinivasan, the vice-chairman and managing director of India Cements told the Business Standard newspaper, “Most of our plants have coal based captive power generation. The cost of captive generation is now more than the grid cost. Hence, we shut down all captive power units and resorted to grid power.”
The International Energy Agency (IEA) forecast in July 2022 that Indian coal demand would grow by 3% year-on-year to 1.16Bnt in 2023 due to expanded electrification and economic growth. In its view, global coal demand will be driven principally by China but also by India to a lesser extent. However, unhelpfully, it added that uncertainty was also rising with ongoing developments in the war in Ukraine having a prominent effect. This is unlikely to assist Indian cement producers and their fuel buyers who will be asking themselves: how long will the current situation last and can the prices be passed on to consumers? There is one small silver lining in the current group of economic storm clouds hanging over cement producers at least. The second quarter of the Indian financial year is monsoon season, when economic activity slows down. It won’t slow the trend down but it may reduce the fuel bill a little.
New Zealand: Fletcher Building Materials recorded consolidated sales of US$5.37bn during its 2022 financial year, up by 4.7% year-on-year from US$5.13bn in the previous year. Its net earnings also rose by 42%, to US$273m from US$193m.
The group's concrete division, which includes Golden Bay Cement, contributed US$556m-worth (9%) of group sales. The figure represents an 8% increase from 2021 financial year levels. The business recorded 'strong performances' across all key product segments, underpinned by 'robust' demand and pricing. It made capital expenditure investments of US$51.1m, including in a waste tyre recycling system upgrade at the Golden Bay cement plant. The latter increased the plant's alternative fuel (AF) substitution to 50% from 35%. The company also continued to focus on developing low-CO2 concrete binders.
Fletcher Building Materials chief executive officer Ross Taylor said "The 2022 financial year has not been without its challenges. Global and national supply chain disruptions have continued into the third year of the Covid-19 pandemic." He added "The New Zealand Commerce Commission recently published its interim market study report into residential building supplies. The final report and recommendations will be published in December 2022 and in the meantime we will continue to work collaboratively with both the commission and the government."
KÇS Kipaş Çimento orders Pyrorotor from KHD Humboldt Wedag
17 August 2022Turkey: KÇS Kipaş Çimento has placed an order with KHD Humboldt Wedag for a Pyrorotor for its Kahramanmaraş cement plant. The supplier says that the equipment will enable the plant's calciner to achieve an alternative fuel (AF) substitution rate of 90%. It will additionally restrict NOx emissions to 800mg/Nm3. After a short shutdown for assemblage of gas duct connections, KHD expects to commission the upgraded system in mid-to-late 2023.
The company says that the KÇS Kipaş Çimento contract represents its 11th Pyrorotor order globally and the first in Turkey.
Lafarge Cement ends Čížkovice cement plant's natural gas reliance through alternative fuels use
17 August 2022Czech Republic: Lafarge Cement says that it has achieved an alternative fuel (AF) thermal substitution rate of 95% at its Čížkovice cement plant. The plant's fuel mix includes contaminant fractions from local plastic recycling. As a result of the move, the plant no longer uses any natural gas in its cement production.
In 2022 as a whole, the producer plans to increase its share of reduced-CO2 cement sales, increase construction waste recycling in its products and reduce its cement's water consumption.
