Colombia: Cementos Argos recorded sales of US$642m in the first quarter of 2022, up by 11% year-on-year from first-quarter 2021. The company’s earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 18% year-on-year to US$88.6m. Cement volumes remained level year-on-year at 3.9Mt. Cementos Argos said that higher inflationary pressures impacted costs associated with raw materials, energy, freight and maintenance, but noted its ‘very good price performance’ across all of its regions. It expects the rise in cement prices to a contribute to a reduction in inflationary cost impacts in the rest of 2022.

CEO Juan Esteban Calle said "Demand for our products and solutions remains very healthy and dynamic in all regions. We are operating at full capacity, despite a challenging environment due to global supply chain disruptions and inflation in energetics and raw material costs. In this environment, we are focused on maximising production at our integrated cement plants to meet our customers' growing needs and on executing a pricing strategy that mitigates the impact of inflation.”

Russia: Eurocement has started an initiative to reduce its reliance on spare parts purchased from outside of the country. The programme is designed to start a phased transition to in-house production of components. One of the first examples of the scheme has been the development and installation of a clutch for a mill at the Sengileevsky cement plant.

The cement producer hopes to source at least 90% of the parts it requires domestically. At present it says that around 30% of the equipment used in the local cement sector is imported. The estimated economic effect will be around Euro14m.

The company has also announced an unscheduled indexation of staff wages to over 7000 workers at 16 cement plants. Indexing of wages is typically used to compensate for inflation. Other measures have also included food support. Vyacheslav Shmatov, the general director of Eurocement, said ““We have decided to increase our support measures for our employees during this difficult time in order to strengthen our work teams. Eurocement is, first of all, people, so the company will continue to take care of its employees.”

International economic sanctions were implemented upon Russia by European and North American countries in response to its invasion of Ukraine in February 2022.

India: An explosion at a cement plant in Gujarat’s Rajkot district has killed three workers. The Times of India newspaper has reported that police have detained two engineers on suspicion of criminal negligence.

US: Conveyor Components has announced the launch of its SBR belt cleaner, a smaller version of its original brush-style belt cleaner. The cleaner uses an electric motor to drive a helical shaped, open face brush. Its hanger rail mounting allows for field customisable mounting on most conveyors. The supplier says that the product efficiently removes fines and carry-back material without clogging or loading.

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.

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.

Japan: Taiheiyo Cement says that the cost of producing its cement has increased throughout 2021. The company said the coal prices have risen due to increased coal demand in China and a reduction in exports from coal-producing countries. It anticipates further rises in the price of coal. Additionally, it foresees a rise in maintenance costs as the equipment at its plants nears the end of its service life. The producer says that it is endeavouring to improve productivity and reduce costs.

Germany: Aumund has announced the launch of its PREMAS 360° packages. The three packages – basic, advanced, premium - combine quality Aumund all-around maintenance and inventory management support, extended warranties, physical inspections, cutting-edge Industry 4.0 monitoring of Aumund and other conveying equipment, technical training, emergency remote support and consultation programmes.

Managing Director Pietro de Michieli said “With PREMAS 360°, Aumund puts customer service to the forefront. Our goal is to reassure machine availability and reliability through the simplicity and flexibility of a fully bundled maintenance solution, to be a partner to our customers assisting them to reach operation excellence.”

Nigeria: Finland-based Wärtsilä has extended its operation and maintenance agreement with Lafarge Africa by another five years. The agreement covers the 100MW Ewekoro power plant, which provides a dedicated supply of electricity to the company’s concrete and cement manufacturing processes. The extension of the deal was signed in July 2021 and it follows a previous 10-year agreement. The scope of the agreement includes the operating crew, performance guarantees, plant availability and spare parts.

The captive Ewekoro plant was supplied and commissioned by Wärtsilä in 2011. It consists of six Wärtsilä 50DF dual-fuel engines, operating primarily on gas, but with the flexibility to automatically switch to liquid fuel in case of a disruption to the gas supply. The engines are also designed to function efficiently with a low-pressure gas supply, a necessity given the region’s vulnerability to supply interruptions.

“We have benefited significantly from the efficient way by which Wärtsilä has operated and maintained this plant for the past 10 years, and we had no hesitation in extending the agreement for a further five years. An uninterrupted reliable supply of electricity is essential to our production, and having our own power plant, built, operated and maintained by Wärtsilä, gives us this assurance,” said Lanre Opakunle, Strategic Sourcing Director, Power & Gas, Middle East & Africa, Holcim.

Wärtsilä has also supplied Lafarge Africa with another 100MW power plant located in Mfamosing.
