Saudi Arabia: Yamama Cement has commissioned its second cement plant, with 20,000t/day in capacity across two clinker lines. The producer invested US$1.25bn in the plant's construction, which was carried out by Germany-based ThyssenKrupp. The facility is equipped with seven raw materials crushers, a 3.7km-long limestone conveyor belt, 110,000t of storage capacity, four Quadropol roller mills, two Dopol preheater towers, two Polro rotary kilns, two Polytrack clinker coolers, three 100,000t clinker silos, four Polycom high-pressure roller mills, six 22,590t and 25,000t cement silos and 22,000m³
in water storage basins. The new plant is situated in the eastern Arabian Desert, 80km from Riyadh.

Yamama Cement also operates the 6.4Mt/yr Al Karj Cement plant, 70km from Riyadh.

France: Heidelberg Materials' subsidiary Ciments Calcia has laid the foundation stone for its construction of a Euro285m CO₂ emissions-reducing upgrade to its Airvault cement plant in Nouvelle-Aquitaine. Ciments Calcia first published its plans for the installation of a new 4000t/day production line to replace both existing lines at the Airvault plant in 2021, with commissioning scheduled for mid-2024.

Germany-based ThyssenKrupp secured the order to supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 vertical roller mill, a 10,000t raw materials tangential blending silo, a single-string, five-stage Dopol cyclone preheater with integral calciner for alternative fuels (with the possibility of conversion to oxyfuel), a Polytrack clinker cooler, a solid recovered fuel preparation line and dedusting systems for the project.

US: National Cement Company of Alabama has reported that the new kiln line at its Ragland cement plant will reduce the plant’s CO₂ emissions by 40%. Its energy consumption will also fall by 30% as a result of the upgrade. The new line includes a 78m-high homogenisation silo, vertical crusher, five-stage preheater and automated clay storage system. AF used in the kiln will include waste tyres, woodchip and sawdust. The new kiln will help in the Ragland cement plant’s transition to 100% Portland limestone cement (PLC) production by 2023, further diminishing its carbon footprint.

Vicat CEO Guy Sidos said "Our ambition is to use AF in all our cement plants around the world. In addition to eliminating fossil fuel energy and replacing it with recycled regional waste, our investments contribute directly to local development. We are proud of the modernisation and transformation of our Ragland site, which was our very first acquisition outside France in 1974."

Asia: FLSmidth says that it has won a contract to supply its low-NO_x ILC preheater, an OK raw mill, an OK cement mill and other equipment to a cement plant in Asia. FLSmidth will deliver the equipment in 2023. The total value of the deal is US$56.1m.

FLSmidth’s cement industry president Carsten Riisberg Lund said "This project showcases FLSmidth’s ability to deliver energy efficient technologies across the full cement flowsheet, and thereby support our customers in both increasing capacity and their sustainability efforts.”

Greece: Titan Cement Group has secured an EU patent for its robotic remote preheater system, previously installed at the company’s Kamari cement plant in Viotia. Titan Cement Group designed the system to maximise operational efficiency and safety.

The company carried out a Euro25m precalciner installation at the Kamari plant in 2021 – 2022.

Mexico: GCC has signed an engineering, procurement and construction (EPC) contract with ThyssenKrupp Polysius for an upgrade to its integrated Samalayuca plant to increase clinker production capacity, raise the usage of alternative fuels and reduce emissions. The project includes the engineering, supply and modification of the preheater, including cyclones, and an extension to the calciner, with the installation of a Prepol SC-S type system to increase the utilisation of alternative fuels. The work also includes fitting a Polytrack type clinker cooler and the installation of a bypass system. The project will begin in 2022 with operations scheduled to start in the second quarter of 2023.

Senegal: France-based Fives has detailed the equipment that it will supply for its construction of a new 6500t/day kiln line at SOCOCIM Industries’ Rufisque cement plant in Dakar Region. The company says that it will supply a preheater, in-line Preca calciner, kiln, TGT filter and Pillard Novaflam burner.

SOCOCIM Industries’ parent company Vicat’s chair and chief executive officer Guy Sidos said “Vicat Group renews its partnership with Fives Group through this major project of building a new line with a strong local dimension, employing local workers and contractors.” He added “This plant will eventually eliminate the use of fossil fuels, reduce our energy consumption and support Senegalese local development, making a higher quality product while doubling our production capacity.”

France: Germany-based ThyssenKrupp has won a contract for the installation of a new 4000t/day clinker line at Ciments Calcia’s Airvault cement plant in Poitou-Charentes. The supplier expects the new line to double the plant’s clinker capacity while also reducing its CO2 emissions. It is intended to replace the two existing lines at the site.

ThyssenKrupp will supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 type vertical roller mill and a 10,000t tangential blending silo to process raw materials for the line. A single-string, five-stage Dopol type cyclone preheater with integral calciner will be supplied that is suitable to use with alternative fuels, with the possibility of conversion to oxyfuel in future. ThyssenKrupp plans to preassemble the preheater, reducing anticipated construction time ‘by several months.’ The plant also includes a Polytrack clinker cooler, a solid recovered fuel (SRF) preparation line and dedusting systems. Commissioning is scheduled for mid-2024.

No value for the project has been disclosed by Ciments Calcia or ThyssenKrupp. However, Ciments Calcia previously announced a proposed investment of Euro300m in January 2021.

Nepal: Udayapur Cement has commenced a US$4.2m upgrade and capacity expansion of its cement plant at Jaljale. The work includes replacing the shell of its 20m rotary kiln by the end of February 2021 and installing a reinforcement suspension preheater system, according to the Kathmandu Post newspaper. It will expand the plant’s capacity by 38% to 0.4Mt/yr from 0.29t/yr. The plant’s current equipment dates to 1988. Company spokesperson Laxman Pokharel said "Since the machines are old, we face frequent problems." He added that this has led to increased costs.

The Nepal government has agreed to loan Udayapur Cement US$34.4m, 80% of the project’s budget.

South Africa: Sephaku Cement has reported a second unexpected kiln stoppage at its integrated Aganang plant in Lichtenburg. It attributed the second delay on the need for a repair to the inside of the kiln. The second stoppage started on 16 October 2021 and was expected to be completed by 26 October 2021. Previously, the kiln was stopped from 30 September 2021 to 6 October 2021 due to preheater refractory material damage caused by a corrosive element in one of the raw materials being used. The producer said that the raw material was subsequently replaced with an alternative option. The subsidiary of Nigeria-based Dangote Cement said that the outages were expected to reduce its sales volumes.
