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.

Belgium: 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.

Greece: Titan Cement Group has secured an EU patent for its robotic remote preheater system, previously installed at the company’s Kamari cement plant in Viotia. Titan Cement Group designed the system to maximise operational efficiency and safety.

The company carried out a Euro25m precalciner installation at the Kamari plant in 2021 – 2022.

UAE: Switzerland-based ABB has carried out an upgrade of the control system for UltraTech Cement subsidiary Star Super Cement at the company's Dubai grinding plant. The supplier says that it installed its ABB Ability 800xA distributed control system (DCS) across three grinding units at the facility. The DCS will communicate between the plant and the company's Ras Al Khaimah clinker plant. ABB previously supplied electric and automation engineering services for the Ras Al Khaimah plant in 2012.

ABB Process Industries global cement lead Max Tschurtschenthaler said that Star Cement's operations will benefit from improved operator visibility, easier maintenance and reduced downtime due to the new systems.

France: The European Commission (EC) has awarded funding under its Innovation Fund 2021 for CRH subsidiary Eqiom’s upgrade to its Lumbres, Hauts-de-France, cement plant. The work includes the replacement of a kiln and the installation of a carbon capture, utilisation and storage (CCUS) system at the plant, in collaboration with Air Liquide. The producer says that the project is one of seven selected under the EC’s K6 programme of innovation funding in line with the EU Green Deal.

Japan: Tokuyama Corporation has signed a memorandum of understanding (MOU) with Mitsubishi Heavy Industries Engineering (MHIENG). Under the agreement, MHIENG will install a carbon capture demonstration plant at the producer's 4.7Mt/yr Nanyo plant in Yamaguchi Prefecture. It plans to commission the trial plant in June 2022 and operate it until March 2023. The supplier hopes to contribute to the early realisation of carbon neutrality in cement and other industrial fields through its work.

Ghana: FLSmidth has secured a contract for the supply of a clay calcination plant at CBI Ghana's 0.6Mt/yr Tema grinding plant in Accra. The supplier says that it will also install a complete grinding station to more than double the plant's production capacity. FLSmidth says that the entire project will reduce the Tema facility's CO₂ footprint by 20%. When commissioned, the new clay calcination plant will be the largest in the world, according to the supplier.

CBI Ghana chief executive officer Frédéric Albrecht said “Ghana is the perfect location for using clay as an environmentally friendly alternative to clinker. West Africa is traditionally a clinker and cement-importing region due to the lack of suitable limestone reserves. Developing countries with their young populations and a growing need for infrastructure and housing represent the future in cement consumption. Calcined clay cements are the most sustainable alternative to traditional clinker-based cement."

India: Shiva Cement's board of directors has approved the launch of a shareholders' vote over plans to increase its Odisha cement plant's capacity by 2Mt/yr. The plan also involves the expansion of the same plant's clinker capacity by 3Mt/yr and the installation of a 12MW waste heat recovery (WHR) plant. In addition to this, the company is seeking to open two new limestone mines with a combined capacity of 1.9 - 3.1Mt/yr at Khatkurbahal, also in Odisha. The company has received Ministry of Environment, Forest and Climate Change approval for all of the plans.
