Latvia: Germany-based Christian Pfeiffer says that it has successfully commissioned the new Broceni grinding plant for Schwenk Latvija. The supplier said that the plant is able to produce cement up to a fineness of 5600 Blaine and is one of the most sustainable grinding plants in Europe.

Schwenk Latvija previously announced a planned investment of Euro34m in a new 170t/day mill and a 12,500t silo at the site of its former Broceni integrated cement plant.

Azerbaijan: Turkey-based Dal Machinery & Design has successfully delivered a ball mill and drive set to Holcim Azerbaijan’s Garadagh cement plant. The supplier says that the equipment will serve cement grinding operations at the plant.

Zimbabwe: Lafarge Zimbabwe’s cement volumes fell by 55% year-on-year in the first quarter of 2022. The company restarted grinding units at its Manresa grinding plant in February 2022 following a roof collapse in October 2021. In a trading update, Lafarge Zimbabwe said that the disruption impacted its profit in the quarter. The producer took the opportunity to decommission one of its ball mills for replacement with a new vertical roller mill in mid-2022.

Chief executive officer Geoffrey Ndugwa said “The company is confident that volumes will recover and grow as the availability of cement stabilises, especially after the new vertical roller mill start-up in the second quarter of 2022.”

Uzbekistan: United Cement Group (UCG) has successfully completed the modernisation of the grinding units at its Kuvasay cement plant in Fergana. The work consisted of installation of protective armour on the inner surface of mill drums and mill ends and the replacement of bar partitions between chambers with sectional partitions. This increased the total mass of the cylpebs to 43t from 39t and improved the mills’ efficiency. UCG also upgraded the units’ dust removal equipment, replacing their original electrostatic precipitators with RIF–0500–03 K and FRKI 360 bag filters. The group carried out the modernisation in collaboration with the Uzsanoatkurilishmateriallari Association and the Fergana Regional Committee for Environmental Safety.

India: UltraTech Cement has successfully commissioned a second clinker line with a capacity of 2.7Mt/yr at its Hirmi cement plant in Chhattisgarh. The company says that it is on track to also commission a new 1.3Mt/yr grinding unit at the plant in mid-2022.

Austria: Lafarge Zement has announced the successful commissioning of a new raw meal mill at its Mannersdorf cement plant in Lower Austria. CEO Berthold Kren congratulated process engineer Nina Wolf and the Mannersdorf plant team for carrying out the Euro23m project.

Argentina: Loma Negra has inaugurated the second production line at its L’Amalí cement plant. The El Cronista newspaper has reported that the InterCement subsidiary invested US$350m in the line, which expands the plant’s capacity by 40%. It previously started up the new line’s kiln in June 2021 but was later forced to suspend all clinker production at the plant due to a union dispute. It previously said it was close to commissioning the grinding mill and despatch unit for the line in August 2021.

Canada: France-based Fives FCB has secured a contract to upgrade the grinding unit at Ciment Québec’s Saint Basile integrated plant in Quebec. The supplier will install two FCB Horomill grinding workshops with FCB TSV 5000 THF classifiers, FCB aerodecanters and flash dryers and Fives TGT process filters. It said that its mills met the customer’s specifications: namely zero water use; minimum power consumption; data processing; and full automation with rapid recipe change.

Ciments Québec president and chief executive officer Luc Papillon said “After a thorough technical review of the various technologies available today for cement grinding, we have selected the Horomill, being confident that it is the best adapted solution for our multiple cements portfolio and our quest to reduce our cement environmental footprint.”

Tanzania: Huaxin Cement has commissioned the grinding system at its Maweni Limestone plant near Tanga. The China-based company acquired the company from Athi River Mining (ARM) Cement in mid-2020. It then invested US$145m on an upgrade to the unit and started trial clinker production in June 2020. The upgraded plant has a production capacity of 1.6Mt/yr. Huaxin Cement says this is the first time it has directly produced cement in Africa rather than exporting it there.
