Nigeria: Dangote Cement will use two vertical roller mills (VRM) from Germany’s Loesche for a new production line at its Obajana plant in Kogi State. The order comprises a six-roller mill for raw cement meal with a capacity of 580t/hr, the largest roller mill for raw material in the Loesche range, and a three-roller mill with a modular design featuring a drive power range of 1000kW for grinding hard coal and lignite with a throughput of up to 70t/hr.

The scope of delivery also includes a LDC classifier for the raw cement mill and a LSKS ZD classifier for the coal mill, which is characterised by individually adjustable grain size separation. The raw material mill is equipped with metal-matrix-compound (MMX) technology. The two mill gear units are equipped with state monitoring and remote access for remote monitoring. Loesche is also contributing to the design and planning of the entire plant as well as the engineering for the electrical measurement, control and regulation technology and complete automation. The delivery date is scheduled for the third quarter of 2018.

The contract partner for this project is China’s Sinoma International Engineering, which has previously installed a seven clinker and cement raw meal VRMs for the Obajana plant. The site has a cement production capacity of over 12Mt/yr and it is the largest cement plant in Sub-Saharan Africa.

India: Commissioning of the new 3000t/day production line at Tancem’s Ariyalur plant in Tamil Nadu is expected to take place in the second quarter of 2018. Construction work is reported as almost complete. Larsen & Toubro (L&T) is the lead contractor on the project with Denmark’s FLSmidth hired by L&T to provide the design, engineering, manufacturing and supply of all equipment. FLSmidth’s scope of supply includes providing key components for the line including raw material crushing equipment, limestone storage, raw and coal grinding, single-string ILC pyro processing system with cooler, cement grinding and packing and loading systems.

Malawi: Shayona Cement plans to more than double production at its integrated plant at Kasungu in Lilongwe. The unit has a clinker production capacity of 1200t/day and this will be increased to 3000t/day. The cement producer is also considering expansion to other countries in the continent.

India: Wonder Cement has ordered two vertical mills from Germany’s Gebr. Pfeiffer for its Nardana plant in Rajasthan. The order includes a MVR 6000 C-6 mill for grinding slag cement and a MPS 3070 BK mill for grinding fuel. Delivery is scheduled for early 2019 and mid-2019 respectively.

The MVR mill will feature a total drive power of 5820kW. Mixed cements will be be ground to a fineness of up to 5% R 45µm. The grinding plant will be designed to process granulated blast-furnace slag with a target fineness of approximately 4500 cm²/g Blaine and blast-furnace cements with different proportions of granulated blast-furnace slag, fly ash and gypsum and different product fineness degree. Wonder Cement has requested the option to grind relatively hot clinker in the mill while at the same time being able to reduce the cement temperature, and alternatively to use cold clinker from stockpiles.

The core components such as the tension system and the grinding rollers will come from Gebr. Pfeiffer in Germany. The grinding bowl and the gearboxes for the mill and classifier will also be delivered from Europe. Gebr. Pfeiffer’s subsidiary, Gebr. Pfeiffer India, will provide the housing parts, the foundation parts and supports of the rollers as well as almost the entire high-efficiency classifier type SLS 5600 BC. Gebr. Pfeiffer India scope of supply will incorporate most of the equipment to complete the grinding plant including the plant fan.

The MPS mill will grind petcoke with a capacity of 40t/hr to a product fineness of 2% R 90µm. It will come with a SLS BK classifier, allowing both coal and petcoke to be ground in the mill, dried with process gases and then classified in the integrated classifier. Due to the high abrasiveness of Indian coal, the mill will be designed with appropriate wear protection.

Most components of the coal mill will be supplied by Gebr. Pfeiffer India. The housing and foundation parts, the grinding bowl and a large part of the power-transmitting parts will be manufactured in India. Setting up the new MPS mill is planned to coincide with the commissioning of the entire kin line.

Vietnam: Fico Tay Ninh Cement (Tafico) plans to start building a new production line at its plant Tan Hoa, Tan Chau District in mid-April 2018. The US$212m project will have a clinker production capacity of 4000t/day, according to the Viet Nam News newspaper. The project is scheduled to be completed in 2020.

Egypt: Khaled Fahmy, the Minister of Environment, has opened a new production line at Arabian Cement Company’s Ain Sokhna plant in Suez. The line uses FLSmidth’s Hotdisc combustion device to allow it to use high levels of alternative fuels, according to the Watani newspaper. The opening was attended by Muhammad Shehab Abdel-Wahab, chief executive of the Egyptian Environmental Affairs Agency, Nahed Youssef, head of waste management organisation, as well as a number of representatives of the financiers, and director of the European Investment Bank.

In 2015 Arabian Cement Company commissioned another Hotdisc installation. At the time is said it had a designed fuel mix of 70% coal and 30% alternative fuels, using a mixture of agricultural wastes, municipal sludge, and refuse-derived fuel (RDF).

Cuba: The Nuevitas cement plant will test LC3 cement, according to the Adelante newspaper. LC3 is a blend of limestone and calcined clay that reduces the amount of clinker used. The plant is one of three units in the country earmarked for upgrades in 2018.

Kenya: The International Finance Corporation (IFC) has committed US$96m to invest in National Cement towards upgrading a cement plant and building new grinding plants. National Cement’s chairman and chief shareholder Narendra Raval is also expected to invest US$102m into the expansion project, according to the Daily Nation newspaper. The company intends to build two grinding plants in Kenya and Uganda and a new 5500t/day clinker production line at its existing integrated plant in Merrueshi in Kenya. It also plans to build a 8MW captive power plant at Merrueshi.

Bangladesh: HeidelbergCement Bangladesh and China National Heavy Machinery have signed a deal to expand the Kanchpur plant near Dhaka, according to ENP Newswire. HeidelbergCement Bangladesh operates two cement grinding plants in the country.

Poland: LafargeHolcim has celebrated investing over Euro95m at its Kujawy cement plant since 2008. As part of the Pomeranian Special Economic Zone, the plant has had a number of upgrades over the last decade and has created over 60 jobs.

Projects at the site have included spending Euro24m on environmental improvements such as installing new filters, building a new clinker silo and four cement silos, and converting the plant to process alternative fuels. Euro56m has been invested on production upgrades including a new cement grinding mill, a new calciner and new constant monitoring systems. Euro18m has been spent on two bulk loading terminals, a new weighbridge and self-loading systems and a new laboratory.
