Pfeiffer SE for the supply of an MPS 3070 BC cement mill for Readymix in Saudi Arabia. The 1100kW drive power mill will grind 30t/hr of granulated blast-furnace slag and 46t/hr of Ordinary Portland Cement to a fineness of 4000cm²/g and 3600cm²/g, respectively. Delivery of the equipment is scheduled for 2015.
US: Essroc Italcementi Group has signed an agreement with Holcim to purchase its slag cement grinding facility in Camden, New Jeresy. As part of the transaction, Essroc will also obtain Holcim's cement terminal in Everett, Massachusetts. The acquisition will finalise when the pending Holcim and Lafarge merger completes later in 2015.
"The acquisition of the Camden slag grinding facility reiterates Essroc's commitment to the northeast market," said Francesco Carantani, Essroc's president and chief executive officer. "With the focus on sustainability and durability, there is a projected growth in the demand and usage of slag cement."
The Camden facility can produce upwards of 700,000t/yr of slag cement. Essroc currently produces slag cement at its Picton, Ontario, and San Juan, Puerto Rico, cement plants and at its slag grinding facility in Middlebranch, Ohio. With the addition of Camden, Essroc has a combined annual production capacity in excess of 1Mt/yr. Holcim's staff in Camden and Everett will join Essroc once the transaction completes.
Korea develops cement from reduced metal slag
13 March 2015Korea: Korean researchers have developed a new cement-producing technology using reduced iron and steel slag.
On 11 March 2014, the Korea Environmental Industry & Technology Institute (KEITI) and the R&D Centre for Valuable Recycling announced that they have succeeded in producing rapid-hardening cement from metal slag reduced during the scrap metal recycling process, adding that the technology is suitable for commercialisation immediately.
Korean authorities bury 720,000t/yr of reduced metal slag in landfills. Using the new technology, Korea will be able to save US$3.79m in reduced slag disposal costs and produce US$254m of rapid-hardening cement. Korea has been relying on imported rapid-hardening cement for more than 80% of its domestic use.
The new technology is also expected to result in a 0.5Mt/yr reduction in CO2 emissions, as it doesn't require the high-temperature melting of slag that is used in the current rapid-hardening cement manufacturing process. The two organisations added that the world could be supplied with US$6bn of cement if the technology was applied to the 17Mt/yr of reduced metal slag produced globally.
