Chile: The Servicio de Evaluación Ambiental (SEA), the country’s environmental body, has approved the environmental impact assessment for a new 0.5Mt/yr grinding plant that Melón is planning to build in Punta Arenas. The unit will have an investment of US$45m, according to the Diario Financiero newspaper. Spain’s Cemengal will supply the mill for the project.

Kuwait: ACICO Cement has ordered a second cement grinding mill from Spain’s Cemengal. The main equipment to be included in the contract includes a 5200 Kws ball mill with all the peripheral equipment from Cemengal and a fourth generation classifier from Magotteaux XP4i-130 for high strength cements. The projected grinding capacity will be 1Mt/yr of cement and the plant will be commissioned within the first half of 2020.

The project scope will include full engineering and complete supply of mechanical, process, electrical and automation equipment as well as the steel manufacturing from the raw materials handling areas up to the cement silos discharge. Site supervision, training and& commissioning will also be provided by Cemengal.

Peru: Chile’s Cementos Bío Bío plans to build a US$20m grinding plant at the Port of Matarani near Arequipa. The cement producer has all the necessary permits in place and it intends to open the unit in the first half of 2020, according to the Diario Financiero newspaper. Spain’s Cemengal will supply a Plug & Grind mill for the project. The plant will have a production capacity of 0.2Mt/yr, although there are plans to double this if the market supports it.

Chile: Spain’s Cemengal has been confirmed as the supplier of a mill for Cementos Melón’s grinding plant at Punta Arenas. The unit will use a Plug & Grind Xtreme modular grinding plant. The contract includes all the mechanical, electrical and automation equipment required for a 0.3Mt/yr modular ball mill and a classifier. Cemengal will deliver the mill by the end of 2019 to allow first cement and commissioning of the plant in the first quarter of 2020.

El Salvador: Guatamala’s Cemento Regional has ordered a Plug&Grind modular grinding unit for a project in El Salvador. The project includes a Plug&Grind Classic, a modular packaging and palletising system, raw material and cement storage halls and silos for bulk dispatching. The new unit is scheduled to be commissioned in the first half of 2019. It will have a production capacity of 12t/hr.

UK: The planning department of East Lothian Council in Scotland has granted planning permission to an upgrade of Tarmac’s Dunbar cement plant. The work will include building a new cement grinding mill, a new cement storage silo and a rail loading facility. The work will also include a shed, belt conveyors pneumatic pipelines and associated works.

In its supporting statement the company said that the new cement mill was necessary to produce new grades of cement required for modern construction and the cement market. The proposed mill will replace two existing mills on the site and is intended to be more energy efficient and quieter than the existing mills. It added that the plant would benefits from rail sidings on both the south and north side of the East Coast Mainline railway line. At present trains are fed only on the south side using adjacent silos where train capacity is already fully used. Additional products are exported by road.

There is lots to mull over for the cement industry from last week’s Global Slag Conference that took place in Prague.

One striking map from Michael Connolly, TMS International, showed the status of slag and steel products in the US. It was a multi-coloured patchwork of different regulatory statuses from approval to be used as a product to regulatory exclusion. This won’t come as a surprise to many readers but even within one country the way slag can be used legally varies.

As this column reported last year after the Euroslag Conference, the European Union can be presented in a similar way. The irony here is that increased use of slag and other secondary cementitious materials (SCM) is exactly the kind of change the cement and concrete industries need to make to decrease their carbon emissions. Constant quibbles over whether slag is a product or a waste undermine this. Happily then that Connolly was able to report progress in the US as lobbying by industry and the US National Slag Association have led to more states legally accepting slag as a product.

However, cement producers have other concerns in addition to environmental ones when it comes to slag usage as Doug Haynes from Smithers Apex explained. Haynes, a former UK steel industry worker turned consultant, spoke around a market report on the future of ferrous slag. His take on Basic Oxygen Furnace (BOF) slag was that despite fuel savings, decreased CO₂ emissions and the benefits of embodied iron when it is used as a raw material for clinker production, it is in the interests of cement producers for slag to be a waste because they then get it for free or at a reduced rate. It’s a similar story to the use of waste-derived fuels powering cement plant kilns where producers want lower fuel costs but waste collectors want value for their product. Unsurprisingly, Haynes wanted cement producers to accept the value embodied in BOF slag.

Charles Zeynel of ZAG International, an SCM trader, then laid out the situation where global SCM supplies are remaining static but cement demand is growing. Coal-fired power station closures are reducing supplies of fly ash, another SCM, placing pressure on existing granulated blast furnace slag (GBS) slag supplies. The message was very much in a slag trader’s favour but instructive nethertheless. If slag is in demand then the price will rise. Anecdotally, the increased number of cement producers at the conference seemed to indicate increased interest of the cement industry in the product.

Lots more speakers followed on topics such as slag beneficiation, grinding advances and new innovations. On grinding, one surprise that popped up was that Spain’s Cemengal has sold a Plug & Grind Vertical mill to CRH Tarmac’s cement plant at Dunbar in Scotland. It is the first such sale of this product in Europe. The last speaker, Jürgen Haunstetter of the German Aerospace Centre, stuck out particularly with his presentation on using slag as a thermal energy storage medium in a concentrated solar power (CSP) plant. This may not seem connected to the cement industry but it is along similar lines to Italcementi’s project at the Aït Baha cement plant in Morocco, which uses a CSP process that can be used with the plant’s waste heat recovery unit.

The Global Slag Conference will return in April 2019 in Aachen, Germany.

UK: Spain’s Cemengal is supplying a 0.5Mt/yr Plug & Grind Vertical mill to Tarmac’s Dunbar cement plant. Work started in April 2018 and the project is expected to be completed by July 2019. The unit follows the Plug & Grind product line’s modular format and it includes a FLSmidth OK Mill 37.3. The mill will be used to grind clinker at the cement plant although the subsidiary of CRH may also use the mill to grind slag. The order is Cemengal’s first Plug & Grind Vertical in Europe.

Honduras: Cementos Argos has ordered two Plug&Grind XL modular grinding units for a project in Honduras. Each mill has a production capacity of 220,000t/yr. The ball mills are 3.0 x 9.5m and they have a power of 1100kW. They also include 50,000m³/hr bag filters and classifiers. The scope of supply includes new cement storage silos for finished product, packing and dispatching equipment. The cement producer announced in early February 2018 that it was planning to spend US$20m on building a new cement grinding plant at Choloma.

Kenya: Ndovu Cement is set to start up a new modular grinding station Plug&Grind XL from Cemengal in the summer of 2017. Installation of the portable grinding plant at the site in Nairobi was completed in June 2017.
