Robtek working on refurbishment project at Khayah Cement
05 February 2025Zimbabwe: South Africa-based Robtek is working on a ‘refurbishment’ project at Khayah Cement’s integrated plant in Harare. The project work on the kiln includes replacing 10 planetary coolers, installing 23m of kiln shell sections and refurbishing eight support rollers. Work on the raw mill includes replacing trunnion bearings, overhauling raw mill bearings, upgrading the internal diaphragm and head wall liners and installing a new double-flap valve to replace the star feeder.
Spain: Votorantim Cimentos Spain will invest €3.2m in a new clinker cooler at its Málaga plant, according to Alimarket. The upgrade will reportedly reduce thermal and electrical energy consumption and avoid approximately 11,000t/yr of CO₂ emissions. The project will receive a €725,960 subsidy from the regional government of Andalusia.
Claudius Peters launches Eta 5.0 clinker cooler
09 December 2024Germany: Claudius Peters has launched its Eta 5.0 clinker cooler. According to the company, Eta 5.0 offers energy savings, lower maintenance downtime and reduced environmental impact. It also features efficiency improvements, such as a new low-pressure-drop system and reduced friction in the transport system. The new cooler can be retrofitted to existing installations with minimal intervention.
Eagle Materials awards contract to thyssenkrupp polysius for modernisation of Laramie plant
28 November 2024US: Eagle Materials has awarded thyssenkrupp Polysius a contract for the modernisation and expansion of its Laramie, Wyoming cement plant. The modernisation project will result in an expansion of the plant's manufacturing capacity to approximately 1.1Mt/yr of cement. The project also includes the installation of an alternative fuel substitution system. The modernisation of the cement plant is expected to deliver benefits such as cost reductions, achieved with lower-cost alternative fuels and natural gas, simplified maintenance and improved operational efficiencies. The production expansion from the new finish mill will supplement the grinding capacity of the existing plant, which already operates with an integrated polysius booster mill. The polytrack ECO cooler will facilitate heat recovery and clinker cooling while improving process reliability. The project, which has received primary regulatory approvals, is slated to commence immediately [in November 2024], with construction scheduled for completion by the second half of 2026.
Turboden launches ORC plant in Saudi Arabia
02 October 2024Saudi Arabia: Turboden, a subsidiary of Mitsubishi Heavy Industries, has announced its first project in Saudi Arabia — a 13MW organic rankine cycle (ORC) power plant at Riyadh Cement Company. This marks the first ORC plant in the Kingdom and the largest globally.
The plant will capture residual heat from the cement plant's clinker coolers and pre-heaters (2 kilns of 5000t/day each), offering high energy efficiency and eliminating water consumption. Sinoma Energy Conservation serves as the project's engineering, procurement and construction contractor.
General manager Andrea La Gioia said "Turboden is honoured to spearhead this groundbreaking project in collaboration with Riyadh Cement Company. With around 460 ORC plants in 52 countries, 50 in ‘waste’ heat recovery application, our ORC technology represents a game-changer in the global energy landscape, and we are proud to support the Kingdom of Saudi Arabia in its transition towards cleaner, more sustainable energy sources."
Holcim invests in new energy projects at Mannersdorf plant
01 October 2024Austria: Holcim is set to significantly reduce its carbon footprint with the installation of a new clinker cooler system and a large-scale photovoltaic system at its Mannersdorf cement plant. The clinker cooler project is valued at approximately €10m, and aims to cut heat consumption and reduce CO₂ emissions by 18,000t/yr. Completion is expected in early 2025. The solar project will be fully operational by 2025, and will cover approximately 15% of the plant’s energy needs and reduce CO₂ emissions by an additional 12,700t/yr. 2.7MW of solar panels were erected at the site of the former chimney on the plant’s premises.
Plant manager Helmut Reiterer said "Sustainability requires decarbonisation, i.e. continuously reducing the CO₂ emissions from our production activities. We are placing an investment focus on energy-efficient production by modernising our machinery, but also on expanding green energy."
India: Adani Cement is upgrading its facility in Himachal Pradesh by installing a new 7800t/day double-stage cooler grate. This upgrade aims to increase efficiency, lower power consumption and clinker temperature and enhance waste heat recovery system performance, according to the company. The project involves replacing the first and second grates of the existing IKN pendulum cooler.
Holcim Deutschland upgrades Beckum cement plant
09 January 2024Germany: Holcim Deutschland has announced for the ‘most extensive’ modernisation of its Beckum cement plant to date. Local press has reported that the modernisation will commence with the installation of a Euro20m pendulum cooler to replace the plant’s existing tube cooler. The new cooler will reduce the plant’s CO2 emissions and make separated CO2 better suited for capture, according to the producer. The Beckum cement plant is the site of an on-going carbon capture trial.
General manager Jan Kristof Peters said “We want to implement all construction work as quickly as possible and with as little noise pollution as possible for the neighbourhood. As in previous years, we ask for our neighbourhood’s understanding.”
Romania: Holcim Romania has successfully upgraded pyroprocessing and cement grinding equipment at its Câmpulung cement plant in Argeș County. Germany-based KHD Humboldt Wedag supplied equipment for the upgrade. For the plant’s pyroprocessing line, this included a downcomer duct, water injection system and induced draught fan, as well as an upgrade to the clinker cooler. Meanwhile, the grinding line has received a new SKS Z 2500 dynamic separator, cyclones, process ducts and separator fan. The supplier says that the upgrade has increased the Câmpulung plant’s clinker capacity and the efficiency of its operations. The work took 14 months to complete from the signing of the contract in mid-2023.
ThyssenKrupp Polysius wins CIMPOR flash activator contract
13 October 2023Ghana: CIMPOR has appointed Germany-based ThyssenKrupp Polysius to build a 1280t/day flash activator for clay. The activator will supply calcined clay for use in the production of cement with a clinker factor as low as 50%. This can reduce the cement’s CO2 emissions by 40% compared with ordinary Portland cement (OPC). The supplier’s contract covers engineering, supply of core equipment and supervision of the project. The equipment includes parts for clay handling, a hammer mill, a flash dryer and preheating and cooling equipment, as well as storage silos. The activator will be natural gas-fired.
Polysius Activated Clay product owner Leo Fit said "Our technology is not only more environmentally friendly, but also creates cost benefits for our customers like CIMPOR. In many regions, limestone is scarce and clinker has to be imported at high cost. At the same time, suitable clay sources are available. The increasing pressure to reduce greenhouse gas emissions is leading cement manufacturers to rethink. They need an alternative that is cost-efficient and at the same time provides high-quality cement. This is exactly what Polysius activated clay offers."
