The supplier says that the 65t/hr-capacity plant will grind cement to a Blaine fineness of 3750cm²/g. The planned MVR 2500 C-4 represents the medium size of the portfolio of the supplier’s modular mill range. Due to the planned installation in the vicinity of a steelworks, blast furnace slag, steelworks slag from an induction furnace and fly ash from an in-house power plant will also be considered as supplementary cementitious materials addition to clinker and gypsum. The mill will be equipped with a 1270kW main drive and an integrated SLS 2650 VC high-performance classifier.
US: Energy company Luminant has awarded Charah Solutions a fly ash management contract extension for its Miami Fort and Zimmer coal-fired power plants in North Bend and Moscow, Ohio. Charah Solutions says that it will pass on the ash for use in concrete production. It will continue to manage the onsite landfill and impoundment operations under its existing contract with Luminant, including material loading, hauling and disposal of approximately 180,000t/yr. In addition, Charah Solutions will be responsible for the beneficiation and utilisation of approximately 400,000t/yr of fly ash. The contract ends in 2027, when both power plants are expected to close.
President and chief executive officer Scott Sewell said “We have been proud to partner with Luminant on its sustainability efforts for many years and are delighted to extend our relationship at these Ohio sites through 2027. We have dramatically reduced the need to landfill fly ash at Miami Fort and Zimmer through our on-going partnership, saving Luminant both expense and valuable landfill space while lowering their risk.” He added “As a result of this expanded agreement, Charah Solutions will continue to provide a reliable supply of high-quality fly ash to ready mix concrete producers in the Midwest, Northeast and deep South through our MultiSource network.”
US: Australia-based Boral Limited says that as part of the review of its North American Fly Ash business, it is considering options such as a potential joint venture, a strategic alliance, divestment to a third-party or continued ownership. Boral has appointed advisors to support an assessment and intends to release an update by August 2021 or earlier if appropriate.
“We have conducted a detailed study of the US fly ash industry and remain confident in the long term demand dynamics for the industry, including significant incremental demand growth potential from the US Government’s proposed new infrastructure program,” said Boral’s chief executive officer and managing director Zlatko Todorcevski. “New opportunities for supply exist from harvesting landfills, imports and natural pozzolans, which we expect will more than offset the decline in fresh fly ash supply as the US transitions away from coal fired power generation.”

STET is supplying the separation equipment, engineering and commissioning services, and an exclusive technology operating license for Salt River Materials. Operations are schedule to start in mid-2021.
Pozzolan business senior vice president Dale Diulus said "Salt River Materials and STET have been working closely to develop a commercially effective beneficiation process improving the quality of the fly ash." He added "We look forward to many years of fly ash sales into the southwestern US markets."

Australia: Boral’s group net sales fell by 9% year-on-year to US$2.10bn in the first half of its 2021 financial year from Euro2.78bn in the corresponding period of its 2020 financial year. Earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 1% to US$376m from US$381m. Net profit after tax remained consistent with previous first-half levels at US$121m. The group noted good value creation from its sale of its 50% stake in USG Boral to Germany-based Knauf for US$1.02bn, which it expects to conclude in the second half of the 2021 financial year.
Chief executive officer and managing director Zlatko Todorcevski said, “While market conditions across the sector remain uncertain, we have made strong early progress to reset our portfolio of businesses, in line with our commitment to shareholders to transform Boral into a more agile, resilient and profitable company. Much work remains to be done but we are well on our way. Our half-year results were impacted, as we expected, by a decline in multi-residential and non-residential construction activity in Australia, particularly in New South Wales, and the completion of a number of major projects ahead of materials demand from new projects coming through. We are in a good position to supply demand when activity in Australia picks up.” He added that housing demand in the North American region strengthened throughout the first half of 2021.
Cement sales revenue and earnings from the group’s Boral Australia subsidiary were reported as stable. The group has also conducted a study of the US fly ash market as part of its ongoing portfolio review. It plans to strengthen its fly ash business in the long term due to expected demand growth.
