India: Shree Cement has ordered two vertical roller (VR) mills from Germany-based Gebr. Pfeiffer for the upcoming clinker line at its Raipur cement plant in Chhattisgarh. The supplier says that one of the mills will grind raw materials and the other will grind coal.

A MVR 6000 R-6 type raw mill will grind 800t/hr of raw material and have a drive power of 8700kW. Gebr. Pfeiffer said, “The grinding rollers of this mill can be equipped with roller tires for raw meal grinding as well as for cement grinding, provided that they have been designed according to the same force module. This saves money, because the identical components of rollers, tensioning system, roller arms, etc. mean that customers can reduce their spare parts inventory, since the same spare parts can be used for a raw meal mill and for a cement mill.” The mill will be equipped with an SLS 6000 VR high-efficiency classifier.

A MPS 2800 BK type mill will be used to grind coal with a capacity of 28t/hr, a drive power of 720kW and be “equipped with the latest design of the integrated SLS 2900 BK high-efficiency classifier optimised for MPS mills.”

The supplier said, “While the core components of the mills as well as the drive units will be supplied by Gebr. Pfeiffer from Europe, the Indian subsidiary Gebr. Pfeiffer (India) will provide components such as the mill and classifier housings, the steel foundation parts as well as internal parts of the classifiers.”

Japan: Taiheiyo Cement has installed three BWZ bucket elevators and a Louise TKF drag chain conveyor supplied by the Hong Kong-based subsidiary of Aumund at its new power plant at Ofunato. The cement producer uses both biomass and coal at the plant.

Two elevators and the drag chain conveyor are used to transport palm kernel shells (PKS) and palm empty fruit bunches (EFB), which are used as alternative fuels in the power plant. Each has a capacity of up to 150t/hr. The conveying concept is designed so that the different materials are kept apart and enter the silo buffer tanks separately. The third bucket elevator is used for coal handling. It is a gravity discharge type BWZ-S elevator with a capacity of up to 35t/hr.

UK: Germany-based Loesche has joined a network of expert companies that “share relevant information and results regarding the reduction of environmental impact and the use of coal and enhanced energy security globally” in becoming an IEA Clean Coal Centre knowledge partner. The company said, “We are excited to be part of this renowned group of companies that aim to improve the environmental impact by use of green technologies, renewable resources, and alternative use of energy sources for more sustainable engineering projects.”

Vietnam: US-based FCT Combustion has published details of a new contract with Vietnam National Coal and Minerals Industry Holding Group (Vinacomin) for the supply of an FCT Turbo-Jet burner to Vinacomin’s 0.6Mt/yr La Hiên plant in Thái Nguyên province. The upgrade aims to enable the use of lower calorific coal while maintaining clinker strength and specific fuel consumption, in order to reduce fuel costs.

FCT Combustion previously provided burners at Vinacomin’s 0.8Mt/yr Quan Trieu cement plant in 2019 and 1.5Mt/yr Quang Son cement plant in 2020, both in Thái Nguyên province.

Zimbabwe: China-based Sino-Zimbabwe Cement Company and LiveTouch Invest, owner of Diamond Cement Zimbabwe, have acquired a six hectare site in the coal mining area of Hwange, Matabeleland North Province, and announced a planned investment of US$30m in the construction of a grinding plant which will grind clinker with waste materials from coal extraction to produce cement.

LiveTouch Invest had previously mooted the idea of a Zimbabwean clinker plant joint venture with South Africa-based PPC in July 2019.

US: Charah Solutions has secured a contract with energy supplier Entergy for provision of environmental services to three coal-fired power plants in Louisiana and Arkansas. The gives Charah Solutions the right to dispose of or market 0.9Mt/yr of coal combustion residuals (CCR), including to cement producers in the region for use as a cement additive.

India: Sagar Cement’s consolidated production volumes at its integrated 2.4Mt/yr Mattampally, Telangana, and 1.0Mt/yr Tadipatri, Andhra Pradesh, plants in January 2020 were 317,000t, up by 4.7% year-on-year from 303,000t in January 2019. Accord Fintech News has reported that consolidated sales in the period fell by 1.6% year-on-year to 315,000t from 320,000t in January 2019.

On 29 January 2020 the Indian Ministry of Environment, Forest and Climate Change granted environmental clearance to Sagar Cements for and upgrade to all three dry lines of its 2.4Mt/yr Mattampally plant to raise its capacity to 5.0Mt/yr. Its clinker capacity will rise from 2.0Mt/yr to 4.8Mt/yr. The expansion also includes a 36MW coal-fired power plant and a 22MW waste heat recovery (WHR) power plant.

India: Udaipur Cement Works has applied for environmental clearance to the government of Rajasthan for the construction of a 5.0Mt/yr integrated cement plant in the state. It plans for the plant to have an additional 2.0Mt/yr grinding capacity, a 30MW waste heat recovery (WHR) power plant and a 25MW coal-fired power plant. Project Today has reported a conjectured value for the project of US$224m.

Pakistan: Pioneer has announced the completion of a new 3.7Mt/yr integrated cement plant with a 12MW waste heat recovery (WHR) power plant and 24MW coal-fired power plant. It said that production and dispatch would start ‘in due course.’ It commenced construction of the facility in 2017.

India: The state government of Maharashtra has granted Aditya Birla Group subsidiary UltraTech Cement environmental clearance for a planned 16MW waste heat recovery (WHR) generator at its 3.6Mt/yr integrated Awarpur plant in Chandrapur district. Projects Today has reported that the state’s Environmental Impact Assessment Authority has also cleared the company’s plan to expand its Korpana coal-fired power plant in Chandrapur to 15MW from 10MW. The producer will place orders for construction contracts in February 2020.
