Turkey: Dal Teknik Makina has completed an upgrade project on Kiln Line 1 at Nuh Çimento in Kocaeli. Key features of the project included increasing the line’s production capacity, decreasing its energy requirements, making savings on power consumption and lowering the exit temperature of the clinker. The work has increased the plant’s production capacity to 3400t/day from 2800t/day. Other benefits of the update include decreasing the specific heat consumption of clinker to 740kcal/kg clinker from 870kcal/kg clinker, reducing electrical power consumption by 7kWh/t and increasing the raw mill capacity to 185t/hr from 160t/hr. The exit temperature of clinker was also reduced to 55^oC plus the ambient temperature.

This project involved the design, manufacturing and erection of the pre-heater tower cyclones group, kiln feed transport system, clinker cooler, kiln hood, removing of dust cyclone at tertiary air duct, cooler vent fan modification, main bag filter duct modification and kiln inlet seal and commissioning of the system.

The first part of the upgrade project was the modification of the pre-heater tower, which as a result reduced the pressure drop, improved heat transfer and separation efficiency, and heat consumption. The second part of the project was the retrofit of the grate cooler. The clinker cooler, kiln hood, cooler fans and cooler vent fan were replaced by Fons Technology International. In this part, kiln hood, cooler vent, exit pipe of waste heat recovery (WHR) unit and tertiary air duct were modified as well. The third part was to replace the horizontal duct of main bag filter inlet with an inclined one in order to avoid dust accumulation. The last step was the replacement of the pneumatic kiln feed by bucket elevator.

The project followed Dal Teknik Makina’s Filter-To-Filter Pyro-Process Concept.

France: Fives FCB has been awarded an engineering, equipment supply and supervision of works contract for the replacement of a kiln at the Lumbres cement plant. The work covers replacing the downstream shell of the 42.2m kiln, including the tyre. The project is part of the cement producer’s plan to adapt Kiln 5 at the site for the installation of a new clinker cooler.

Burkina Faso: Cimburkina has started upgrading its Kossodo cement grinding plant. The US$2.85m project will centre on the installation of a new mill. This will double its production capacity to 2Mt/yr, according to the Sidwaya newspaper. Other works will include a new 2000t limestone silo and a new bagging unit. The new mill is scheduled to start production in December 2018.

The plant, a subsidiary of Germany’s HeidelbergCement, produces two types of cement: CEM II 42.5 R and CEM II BL 32.5 R. Clinker for production comes from the group’s Scantogo plant in Togo.

Ivory Coast: Jean-Claude Brou, the Minister of Industry and Mines, has inaugurated a new mill at LafargeHolcim Ivory Coast’s plant at Abidjan. The new mill has increased the unit’s production capacity to 2Mt/yr, according to the Agence Ivoirienne de Presse. LafargeHolcim Ivory Coast re-used a ball mill from a Spanish cement plant that was dismantled and shipped to Abidjan. The mill uses a 4.5MW motor and the cement producer says it is the largest horizontal ball mill in French-speaking West Africa. The project cost US$28.5m.

India: JK Cement has received approval for an upgrade at its Mangrol cement plant near Chittorgarh in Rajasthan. The plant will have an investment of US$312m, according to Accord Fintech. Following the expansion the plant will have a cement production capacity of 4.2Mt/yr. Cement grinding will be supported by units in Uttar Pradesh and Gujarat.

US: United States Lime & Minerals grew its sales revenue in 2017 due to higher business from its oil and gas services and industrial customers. Total revenue grew by 4% year-on-year to US$145m in 2017 from US$139m in 2016. The producer raised the price of its lime and limestone products in 2017.

“Demand for our lime and limestone products in the fourth quarter and full year 2017 remained steady. In addition to the St Clair replacement kiln project, we continue to seek innovative ways to enhance efficiencies at all of our facilities so we can compete in what remains a challenging pricing environment,” said Timothy W Byrne, president and chief executive officer of United States Lime & Minerals.

Algeria: Biskria Cement has started the kiln on its second new production line at its plant in Biskra. The 6000t/day line was supplied by China’s Sinoma. The Chinese plant builder announced the US$267m order in 2015. It included two production lines from raw materials to despatch. The cement producer operates three cement production lines at its plant with a production capacity of 4Mt/yr.

Pakistan: Lucky Cement’s profit after tax fell by 2% year-on-year to US$77.6m in the half year to 31 December 2017 from US$79m in the same period in 2016. The cement producer said that its cost of sales had increased by 21% due to rising coal and other fuels prices. Its sales revenue grew by 5.2% to US$297m from US$283m. Its cement production rose by 5.4% to 3.68Mt from 3.49Mt.

The company completed a new 1.25Mt/yr production line at its Karachi cement plant in December 2017. It is currently seeking government approval to build a new 2.3Mt/yr plant in Punjab Province. However due to the delay it is considering expanding its Pezu plant by 2.3Mt/yr instead. The cement producer also expanded its grinding plant in Iraq by 0.87Mt/yr to 1.74Mt/yr.

Pakistan: The Industries, Commerce and Investment department of the Government of Punjab has confirmed that it is banning the construction of new cement plants and the enlargement of existing plants. The decision follows approval by chief minister Shehbaz Sharif, according to the Nation newspaper. It is in response to a number of environmental issues allegedly caused by cement production in the province including damage to water tables and increased air pollution. Final confirmation of the ban came in response to the Supreme Court enforcing a similar ban near the Katas Raj Temples in the state.

Finland: Engineering equipment supplier Metso has upgraded its Tampere plant to focus on track-mounted crushing units. The new assembly line has increased mobile crushing plant production by 25%. It says it can build a 50t track-mounted crushing plant in two working days.

"Demand for mobile Lokotrack crushers for aggregates took an upward turn 18 months ago, so the timing of our investment in capacity growth was right. We want to ensure that our production capacity can meet customers' growing needs," said Markku Simula, President, Aggregates Equipment business area at Metso.

The new assembly line has six assembly stations instead of the previous five. Currently, the line is used for assembling the company’s most popular crusher models. Assembly of larger and more complex models will begin in the spring of 2018.
Aggregate crushing plants have been built in Tampere for 98 years. The first jaw crusher was completed at the Lokomo workshop in 1921. Production of track-mounted crushing plants began in 1985.
