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.

Finland: The VTT Technical Research Centre of Finland and Finnsementti have revealed work on the Decarbonate project to test a 12m electrically-heated rotary kiln. Other partners on the initiative included Nordkalk and UPM. Precalcination was tested as well as the projection of quick lime. The eventual goal is to use electricity from renewable sources to power the kiln and then capture the CO₂ released for utilisation.

The Decarbonate project has been exploring CO₂ capture and utilisation concepts that can be commercialised. It has run for two years since late 2019 and has funding of Euro1.2m. It has also looked at oxyfuel and electrolysis experiments.

India: Shree Cement has hired FLSmidth to supply a 11,5000t/day kiln line for its planned Nawalgarh, Rajasthan, cement plant. The line will consist of a six-stage preheater and a three-support kiln. The supplier will also deliver an OK vertical roller mill, which it says has a 5 – 10% lower energy consumption than a standard vertical roller mill. The project focuses on sustainable productivity and emissions control. Shree Cement has opted for JetFlex burners to give the lowest possible nitrous oxide emissions for various fuel types.

Shree Cement managing director Prashant Bangur said “Based on the experience of working with FLSmidth on the installation of a 9,000t/day pyro system at the Raipur, Chhattisgarh, cement plant earlier this year, we felt confident about approaching Carsten Riisberg Lund and his team regarding the Rajasthan project.” He added “Being recognised as a Sustainability Champion by the World Economic Forum is a testament of our emphasis on sustainability at every stage of our operations. The new line will push that agenda even further in terms of lowering the benchmarks on energy consumption and emissions, and thereby reducing our environmental footprint.”

FLSmidth also supplied a second OK mill for Shree Cement’s operations in Kolkata, West Bengal.

India: Gujarat Sidhee Cement has restarted the kiln at its Sidheegram cement plant in Gujarat. Reuters News has reported that full operations will commence at the plant on 25 September 2021. The producer shut down its kiln line for routine maintenance on 7 September 2021.

Canada: Three people, of whom two are in a serious condition, are in hospital in Toronto following an explosion at Lehigh Cement’s Picton cement plant in Prince Edward County, Ontario. The Kingston Whig Standard newspaper has reported that the individuals are believed to be external contractors who were carrying out repairs at the plant. The explosion occurred in a kiln on the morning of 7 September 2021.

The Ontario Ministry of Labour and fire services continue to investigate the incident.

India: Gujarat Sidhee Cement has shut down the kiln line of its Sidheegram, Gujarat, cement plant for 17 – 20 days. India InfoLine News Service has reported that the company will carry out routine maintenance on the plant during the shutdown. It says that grinding and dispatch of cement will continue as usual.

Uzbekistan: Germany-based IKN has secured a contract for process integration and equipment design for a new kiln line at Qizilqumsement’s Qizilqumsement cement plant. The supplier’s remit includes the pyroprocessing line, preheater, kiln and cooler including ID fan, kiln drive and burners. It plans to use a six-stage preheater, the region’s first. Commissioning is scheduled for 2022.

France: Fives has refurbished a rotary kiln at SOKA’s (Société Kaolinière Armoricaine) kaolin plant at Quessoy. Work on the project included: implementing a new nose-ring fitted with a downstream seal, to reduce false air flow and improve brick-lining lifetime; machining the tyres, replacing of the rollers and installing a new lubrication system, to improve the kiln scanning and enable an homogenous wear of the contact areas; and installing a grease spraying system fitted with a new girth gear housing to prevent advanced wear initiated by grease contamination. SOKA specialises in the extraction, processing and calcination of raw kaolin, refined kaolin and calcined kaolin in France and Ukraine.

Philippines: Cemex Philippines Solid Cement plant in Antipolo has lifted a new rotary kiln into position as part of a US$235m installation of a new production line at the site. Once complete the new line will add 1.5Mt/yr to the unit’s production capacity increasing the total to 3.4Mt/yr. The new production line will reuse waste hot gases to dry raw materials and high efficiency bag filters reduce improve emissions control. Cemex is also using its proprietary Low Temperature Clinker technology to reduce carbon dioxide emissions.

"This milestone demonstrates our full commitment to the development of the country and brings us closer to further strengthening our position in providing the infrastructure and building needs for economic development," said Ignacio Mijares, the chief executive officer (CEO) and president of Cemex Holdings Philippines.

China-based CBMI Construction has been contracted to build the new line. It lifted the new kiln in two days. Tong Laigou, chairman and general manager of CBMI Construction, said that the CBMI and Cemex Philippines' teams worked under strict protocols to secure the safety of the site.

France: LafargeHolcim subsidiary Lafarge France has installed a new rotary kiln at its Martres-Tolosane cement plant. The installation is part of a Euro120m project to build a new production line at the site. The work will also increase the plant’s alternative fuels (AF) substitution rate to 80% from 30%.

The company said, “Once completed the work will increase the productivity of the cement plant, while reducing its environmental impact. The plant will be equipped with the latest environmental technologies, thus increasing the share of energy recovery from waste and its use in the production of clinker. The work will reduce energy consumption, reduce the carbon dioxide (CO₂) footprint by 25% - 30% per tonne of cement and create local circular economy loops with partners in the greater South-West.” The on-going upgrade to the plant is on schedule for completion in November 2021.
