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.”

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.

Pakistan: Askari Cement has awarded a contract to Germany-based Gebr. Pfeiffer for the supply of three of its MVR vertical roller mills to replace the existing mills at its Nizampur cement plant.

The other mill, an MVR 5000 R-4 raw meal mill, will grind 520t/hr of clinker to a fineness of 12% R90µm. The Chinese contractor Hefei Cement Research & Design Institute will install an SLS V high-efficiency classifier on each of the mills. The upgraded plant is scheduled for commissioning in mid-late 2022.
