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.

India: Mamata Banerjee, the chief minister of West Bengal, has inaugurated JSW Cement’s plant at Salboni. The US$125m grinding plant has a production capacity of 2.4Mt/yr, according to the Press Trust of India. It started commercial production at the site in July 2017 with plans to manufacture Portland Slag Cement. The cement producer is already preparing upgrades at the unit including a US$15.6m captive power plant with a capacity of 18MW and a US$47m production capacity increase of 1.2Mt/yr.

India: KIC Metaliks plans to build a 300t/day slag cement grinding plant at its pig iron plant at Raturia in the Bardhaman district of West Bengal. The project is part of a wider upgrade at the site to turn it into a steel plant, according to Projects Today. Other upgrades a direct reduced iron kilns, a sinter plant, a rolling mill, a pulverised coal injection plant and a captive power plant. The upgrade plans are valued at around US$93m. The company is awaiting environmental clearance for the project.

Russia: NLMK Group has completed hot-testing of its new crushing and screening unit for the processing of steelmaking slag at its Lipetsk plant. The project will double the amount of scrap, or ‘metal inclusions‘, extracted from waste and returned to the production process. The new unit will process 2.4Mt/yr of slag, replacing an obsolete unit, which processed 1.7Mt/yr of slag. Metal extraction efficiency at the new unit will be as high as 95%, which will minimise the consumption of iron ore and scrap in pig iron and steelmaking operations through replacement with recoverables. The project had an investment of US$7.2m.

“The new unit will process the entire volume of our steelmaking slag, which is about 2.2Mt/yr, as well as allowing us to eliminate the need to process slag via third parties. The unit will also help us to recycle previously accumulated waste. This Strategy 2017 project is our next step towards increasing the role of recycling in bringing down steelmaking costs and reducing our environmental footprint,” said Sergei Filatov, the managing director of Novolipetsk.

Recovering production waste is one of NLMK’s priorities as part of its operational efficiency improvement efforts. NLMK Group is currently building a new briquetting plant at the Lipetsk plant. Briquettes will be manufactured from a mix of iron ore concentrate and blast furnace slag formed in the process of wet blast furnace gas cleaning. The plant will recycle more than 350,000t/yr of blast furnace waste.

India: According to local media, Sunvik Steels plans to expand its integrated steel plant in Jodidevarahalli, Tumakuru, Karnataka. The estimated cost of the project is US$86.8m.

The existing plant has three 100t/day direct reduced iron (DRI) kilns, a 12t/hr induction furnace based steel melting shop, a 100t/day roller mill, a 10MW captive power plant, a 2000bricks/day fly-ash brick plant and one 15t/day slag crusher and beneficiation plant. The proposed expansion will see the plant consist of one 200t/day DRI kiln, a 500t/day induction furnace based steel melting shop, a 500t/day roller mill, 5MW and 10MW captive power plants, a 300t/day blast furnace, two 100t/day tunnel kilns, a 2000t/day iron ore pelletisation and beneficiation, a 6000bricks/day fly-ash brick plant, a 100t/day fly-ash beneficiation plant and a 30t/day slag crusher and beneficiation plant. The project is waiting for environmental clearance.
