Russia: VostokCement subsidiary Teploozersky Cement has reported the successful completion of scheduled maintenance work on the rotary kiln at its 0.8Mt/yr integrated Teploozersky cement plant in Birobidzhan Oblast. Esmerk Russian News has reported that the work consisted of adjusting furnace units’ positions replacing worn sections of the lining.

Algeria: Fives has reported that it has installed and produced a batch of clinker with a new 6000t/day FCB kiln line at Entreprise des Ciments et Dérivés d'El Chellif (ECDE)’s integrated 1.0Mt/yr Chlef cement plant. When commissioned, the line will bring the plant’s capacity to 3.2Mt/yr.

Tanzania: Manyara Cement has shared plans for a 0.2Mt/yr integrated cement plant in Hanang district, for which it has already acquired limestone and pumice extraction licences for sites around Mount Hanang. The plant will use a vertical shaft kiln.

The plant will sell cement on the northern Tanzanian and southern Kenyan markets.

Russia: Eurocement subsidiary Kavkazcement has installed and commissioned a dry kiln to replace its reserve kiln at its plant in the Republic of Karachay-Cherkessia. The new kiln is part of a Euro5.79m investment which will increase the current 3.1Mt/yr integrated plant’s capacity by over 40% to 4.4Mt/yr when commissioned in mid-2020. Oleg Lopatin, Kavkazcement director general, said “A significant increase in the plant’s workload was made possible by the high demand for our cements.”

Egypt: Germany-based HeidelbergCement subsidiary Egyptian Tourah Portland Cement has said that it will accept offers for some items proposed for sale under auction of equipment from its decommissioned 1.0Mt/yr Tourah plant in Tura near Cairo, from which it expects to raise a total of Euro1.71m. The company said it had received ‘several bids.’ It stopped production in June 2019 due to its inability to cover costs.

US: Ragland Town and St. Clair County administrators have approved France-based Vicat’s US subsidiary National Cement’s plans for a second kiln at its 1.9Mt/yr Ragland cement plant in Alabama, construction of which will begin in early 2020. Birmingham Business Journal has reported that National Cement, which has had legal permission to build a second line since 2006, has announced that the new kiln will enter clinker production in 2022 following a total investment of US$250. National Cement is Ragland’s largest employer, with a staff of 132 at the 111-year-old Ragland plant.

Switzerland: Maerz has reported the successful installation of two Maerz PFR lime kilns with a capacity of 200t/day and 300t/day at Daesung MDI in South Korea, which was commissioned on 19 October 2019. The company also installed a 150t/day E2 two-shaft lime kiln at Easternbulk Lime Products Private Ltd in July 2019. Three further new plants with Maerz kilns are scheduled to enter operation in 2020 in China, Mexico and Russia and a second kiln will increase production of petcoke at Caleras’ San Juan plant in Argentina beginning in mid-2020.

US: California-based Heliogen has developed concentrated solar-thermal plants (CSPs) with the ability to focus sunlight to generate temperatures over 1000°C by micro-adjusting mirrors using computer technology. It has now engaged Parsons Corporation to build arrays of its CSPs for installation in cement pre-calciners. Requiring 900°C heat, these represent the largest part of the industry’s CO₂ output. The technology will firstly reduce this by replacing fossil fuels with a clean heat source, which moreover entirely bypasses the electrical grid. Heliogen CEO Bill Gross says that the installations will make carbon capture and storage (CCS) of the remaining CO₂ emissions from the conversion of limestone to lime easier by removing other pollutants. Heliogen is now targeting 1500°C from its CSPs, which would enable them to supersede cement fuels in kilns.

Russia: Vostokcement subsidiary Spasskcement received a ninth belt to serve as a back-up for conveying materials into one of its two kilns at its Spasskcement plant. The belt is 7.65m wide and was manufactured in Louyang, China.

Cuba: Following 18 months of reduced operations in which time maintenance and repairs on its grey cement kilns were carried out, Corporacion Cementos Cubanos’ 0.7Mt/yr Siguaney plant is once more fully operational across its four wet lines.
