Russia: Cemros has started a US$3m upgrade project on cement mill five at its integrated Katavsky plant near Chelyabinsk. The work will see the introduction of a new closed-loop system with a separator. Following its installation, the mill will have a cement output of 114,000t/yr. The upgrade should also deliver an energy saving of up to 30%. Just under half the funding for the project was supplied in the form of a loan from the government. The upgraded mill is expected to be operational in September 2023.

Kenya: Savannah Cement has hired China-based Sinoma International Engineering for construction of its upcoming 2.92Mt/yr Kitui clinker plant in Eastern Province. The plant will additionally have a 900,000t/yr grinding unit, a 35MW fossil fuel-fired captive power plant and a 13MW waste heat recovery (WHR) system. Savannah Cement chair Benson Ndeta said that the plant will convert to 100% solar and WHR-powered production by the end of 2029.

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.
