Australia: Germany-based Christian Pfeiffer has received an order for a grinding circuit comprising a 16.3m-long ball mill and a QDK T 250-Z type separator from Hallett Construction Materials. The circuit will have a capacity of 84t/hr, according to the supplier. Hallett Construction Materials plans to use the equipment at its upcoming Port Augusta slag cement grinding plant. The plant is scheduled for commissioning in January 2024.

Hallett Construction Materials chief executive officer Kane Salisbury said, “For us, the sustainability of the plant is the highest priority. That’s why we manufacture cement containing 100% slag.” Salisbury added “The Christian Pfeiffer process experts convinced us that the ball mill, in combination with a high efficiency separator, is the best system to serve our requirements.”

Australia: Hallett Group plans to establish a slag cement grinding plant in Port Augusta, South Australia. Magnet News has reported the cost of the project as US$83.9m, towards which the producer has received US$13.4m in government funding. The plant will produce cement using South Australian ground granulated blast furnace slag (GGBFS) from Nyrstar’s Port Pirie and Liberty Primary Steel’s Whyalla steel refineries and fly ash from the site of the former Port Augusta power plant. Its operations will be 100% renewably powered. An accompanying new distribution facility at Port Adelaide will ship the cement to markets. The project will create 50 new jobs.

When the Port Augusta grinding plant becomes operational in 2023, its products will reduce regional CO₂ emissions by 300,000t/yr, subsequently rising to 1Mt/yr, according to the company’s expansion plans.

Hallett Group chief executive officer Kane Salisbury said "We're talking about 1% of the entire country's 2030 [CO₂ reduction] commitment, delivered through this project." Salisbury added "We're looking at turning South Australia into a global leader in manufacturing green cement."

UK: A team of Hanson employees has produced a sign from recycled materials from around the company’s 1.0Mt/yr Purfleet slag cement grinding plant. The 6m-long luminous sign, which reads ‘NHS Thank You,’ has been installed at the plant on the mill three tower overlooking the QE2 Dartford Crossing. Hanson Purfleet plant manager Warren Scott said, “The team wanted to show their appreciation for the NHS and key workers and came up with and executed this idea in their own time.”

Hanson has kept ‘a number of key sites’ open through the coronavirus outbreak in order ‘to supply key national infrastructure projects or to provide maintenance materials to critical sectors.’ Hanson has furloughed part of its staff under the government’s Coronavirus Job Retention Scheme.

India: Gebr. Pfeiffer has announced that it has received an order for one MVR 6000 C-6 roller mill for Chettinad Cement Corp. Pvt. Ltd.’s upcoming 2.0Mt/yr Vishakapatnam granulated blast-furnace slag (GBFS) and slag cement
Grinding plant in Andhra Pradesh. Gebr. Pfeiffer said the mill will grind slag and cement to a fineness of between 3000 and 3800 blaine at a rate of between 235t/hr and 340t/hr. It says the mill improves plant availability by the active redundancy of the grinding rollers, enabling mill operation with reduced rollers in the event of maintenance work or a malfunction.
