Government of Quebec allocates US$36m towards upgrade at Ciment Québec’s Saint Basile plant
04 May 2022Canada: The Government of Quebec says it will allocate up to US$36m towards a US$110m upgrade project at Ciment Québec’s integrated St Basile plant. The plant intends to build a new grinding unit including new reception, storage and raw material handling systems and two mills. The work is intended to reduce the CO2 emissions from the plant. France-based Fives FCB previously said that it had won a contract for the project. Commissioning of the new equipment is scheduled for the beginning of 2024.
Domicem awards upgrade of limestone reclaiming system at San Cristobal plant to Bedeschi
04 May 2022Dominican Republic: Colacem Group subsidiary Domicem has awarded the contract to upgrade the limestone reclaiming system at its integrated Sabana Grande de Palenque cement plant in San Cristóbal province to Italy-based Bedeschi. The original stacking and reclaiming equipment, installed by Bedeschi in 2004, allows clay and limestone handling at the plant. The upgraded machine will improve the limestone reclaiming system, increasing its capacity from 200t/hr to 360t/hr, the capacity needed in order to feed a new production line that is being installed at the plant.
India: ACC’s earnings before taxation, interest, depreciation and amortisation (EBTIDA) fell by 26% year-on-year to US$83.1m in the first quarter of 2022 from US$113m in the same period in 2021. Net sales rose by 3% to US$566m from US$552m. Sales volumes of cement dropped by 3% to 7.71Mt but volumes of ready-mixed concrete grew by 5% to 0.87Mm3. The subsidiary of Ambuja Cement and Holcim said that its costs had been negatively affected by a global rise in fuel costs caused by ‘geopolitical events.’
The cement producer said that its new integrated plant at Ametha in Madhya Pradesh is scheduled to be commissioned in the fourth quarter of 2022. It commissioned an upgrade to its Tikaria grinding plant in Uttar Pradesh in February 2022. Waste heat recovery unit projects at its Jamul and Kymore plants are ‘on track’ and the board of ACC has approved the next phase of similar projects at its Chanda and Wadi plants.
Switzerland: Jura Cement has commissioned a regenerative thermal oxidation system at its Wildegg plant. The air pollution control system, supplied by Dürr, was installed to meet anticipated lower gas emission limits for carbon monoxide, hydrocarbons, and ammonia (NH3).
Titan America to expand Norfolk terminal in Virginia
12 April 2022US: Titan America plans to spend around US$37m towards expanding its Norfolk terminal in Chesapeake, Virginia. The plans at the terminal, run by subsidiary Roanoke Cement Company, include building a 70,000t dome, enlarging truck and railway capacity and enabling the site to import and distribute raw materials such as fly ash, slag and aggregates. At present the unit has a bulk storage capacity of 35,000t. Titan says that the upgrade will enable it to meet growing demand for its products in the Mid-Atlantic region. The project also follows a similar investment in a 70,000t dome currently under construction at Titan's import terminal in Tampa, Florida.
"The major expansion and modernisation of these two marine terminals is another important step toward meeting fast-growing demand for our products and services in critical infrastructure, commercial and residential projects in our communities," said Bill Zarkalis, president and chief executive officer, Titan America.
The dome and associated expansion projects are scheduled for completion in 2023.
Elex starts up electrostatic precipitator at National Cement’s Ragland plant in Alabama
12 April 2022US: Switzerland-based Elex has completed a cold start-up of an electrostatic precipitator (ESP) it has supplied to National Cement’s Ragland plant in Alabama. The ESP will be used for primary dedusting and it has a separation area of approximately 7000m2. The cement plant, owned by France-based Vicat, is currently building a new 5000t/day production line that is due to be commissioned in mid-2022.
India: Aumund Engineering India has been selected by ACC to refurbish a 175.3m high bucket elevator, the tallest in the world. The elevator is installed at ACC’s Wadi Cement plant in Karnataka where it is used for raw meal pre-heater transport at a rate of 600t/hr.
Originally, the machine was fitted with a steel cord belt of width 1320mm and tension rating of 3150N/mm. Aumund has decided to offer an alternative based on its own design concept resulting in a belt width of 1300mm but with higher tension rating of 4000N/mm with a bucket size of 1250mm at bucket spacing of 450mm. The Aumund belt concept will use continuous close pitch longitudinal ropes without rope free bucket mounting spaces. However, it will use additional wire ropes running laterally across the width of the belt adding lateral stiffness without significantly changing the belt longitudinal flexibility. This cross-stabilised construction is intended to improve stability to the belt with improved bucket fixing.
To make the necessary belt punching, Aumund has developed a special punching machine design which gives clean fixing holes that are accurately aligned relative to the belt edge and at precisely the correct pitch. The belt is held in a cassette and advanced automatically under the punching frame using a precision encoder to measure the pitch. The belts are prepared at the Aumund production in Rheinberg, Germany and shipped to site at the exact required dimensions including a prepared joint and the required clamping connection.
In addition to the new belt the elevator will also be fitted with new drive pulley including friction linings and rubber bucket mounting strips. The casings, inlet and outlet plus the complete drive unit remain unchanged.
No commissioning date for the project has been announced.
Russia: SibCem subsidiary Angarskcement has restarted kiln four at its plant in Angarsk after a decade of inactivity. The kiln was last used in 2010. The decision to restart the kiln was made in 2021 due to growing demand for building materials in the Irkutsk region and an increase in cement sales. Kiln four was first lit in 1960 and was later upgraded in the early 1980s. It has a clinker production capacity of 720t/day. All four kilns are now running at the cement plant.
Ghana: Denmark-based Investeringsfonden for Udviklingslande (IFU) and Norway-based Norfund have invested US$27.9m in CBI Ghana. The funding will support the cement producer’s upgrade of a clay calcination unit at its 0.6Mt/yr Tema grinding plant in Accra. Denmark-based FLSmidth is supplying the equipment for the project.
CBR completes Antoing cement plant upgrade
08 April 2022Belgium: CBR has successfully completed an upgrade of systems connected to the kiln of its 0.8Mt/yr Antoing cement plant. The company says that it has modernised the kiln gas cycle, reducing the plant’s power consumption by 2.5%.
The Antoing cement plant previously underwent a capacity expansion and alternative fuels (AF) substitution-increasing upgrade to its kiln line in late 2020.
