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.
Loesche completes work on world’s largest slag mill for Shanxi Taigang Stainless Steel Co
21 July 2014China: Loesche GmbH has completed work on the largest slag mill in the world for Shanxi Taigang Stainless Steel Co (TISCO) in Taiyuan, China achieving a new record product rate of producing 255t/hr blast-furnace slag meal. The Loesche type LM 63.3+3 vertical mill for grinding granulated blastfurnace slag was originally ordered by the Taigang Group International Trade Co in September 2011. It started operation in March 2014.
At the TISCO steelworks the LM 63.3+3 has now been used for the pure grinding of granulated blast-furnace slag for the first time. The mill is driven by a motor with an output of 7400kW, the most powerful motor to have been installed so far by Loesche in a mill. The projected guarantee values of 255t/ hr granulated blast-furnace slag at a fineness of 4400 Blaine are reliably attained here. This is also ensured by the newly developed Loesche LDC classifier, used in the grinding plant and ideally customised to the Loesche mills.
The first Loesche LM 63.3+3 mill started production at Nallalingayapalli, India in 2009. It attains a peak value of 367t/hr ordinary portland cement at 3000 Blaine or 371t/hr portland pozzolana cement at 3400 Blaine.
Turkey: Gebr. Pfeiffer SE has received another order from Bolu Cimento Sanayii A.S., Turkey. In addition to the three MPS mills that Bolu Cimento ordered in December 2013 for the Kazan, Ankara Province plant, this order will see Gebr. Pfeiffer supply an MPS 4500 BC mill for the grinding of granulated blast furnace slag, which will be set up at Bolu Province plant. The mill will be identical to the cement mill that will be installed in Kazan.
The mill is designed to reach a throughput rate of 85t/hr of slag, ground to a product fineness of 4500 - 4750cm²/g. Gebr. Pfeiffer's scope will include the core components of the mill and classifier as well as the mill gearbox. The required drawings and parts lists for the local manufacture of housing and steel parts as well as documents for quality control will also be produced and supplied.
The delivery of the mill scheduled to start at the end of 2014 and will have been completed by early 2015.
British watchdog to force HeidelbergCement to sell slag plant
20 January 2014UK: Britain's competition watchdog has asked HeidelbergCement to sell one of its three plants that produces ground granulated blast furnace slag in the UK. The Competition Commission said the move is intended to increase competition.
UK Competition Commission to create new cement producer
15 January 2014UK: The Competition Commission (CC) has demanded that Lafarge Tarmac sell one of its cement plants in the UK to create a fifth cement company in the country to increase competition in the market. The CC also intends to increase competition in the supply chain for ground granulated blast furnace slag (GGBS) by forcing Hanson to sell one of its GGBS production facilities. The CC is also introducing measures to limit the flow of information and data concerning cement production and price announcements.
"We believe that the entry of a new, independent cement producer is the only way to disturb the established structure and behaviour in this market which has persisted for a number of years and led to higher prices for customers," said CC Deputy Chairman and Chairman of the Inquiry Group, Professor Martin Cave.
The measures follow a two year investigation which found that both structure and the conduct in the cement sector restricts competition by aiding coordination between the three largest producers: Lafarge Tarmac, Cemex and Hanson. Competition problems also arose from the UK having only one domestic producer of GGBS in the UK (Hanson) with exclusive rights to use the output of Lafarge Tarmac, the single domestic producer of granulated blast furnace slag (GBS), which is the main raw material input into GGBS. The CC estimates that the lack of competition for both of these issues may have cost UK customers up to Euro60m/yr.
The final report follows the publication of the CC's provisional findings in May 2013 and an Addendum to the provisional findings and its provisional decision on remedies in October 2013.
Loesche installs dry-processing plant for stainless steel slag
27 November 2013Belgium: Loesche has developed a dry refining process for stainless steel slag (EDS), with CALA Aufbereitungstechnik GmbH & Co. KG, to obtain a high-purity metallic portion and a valuable, metal and mineral-free filler material at the same time. Belgian company RECOVAL assigned Loesche with the engineering and delivery of a turnkey processing plant primarily for stainless steel slag.
In the recovery process, and purely by the addition of CO2 to the EDS, finished components with structural properties like those of concrete are produced without the use of conventional cement. A Loesche Vertical Mill type LM 15.2M will be at the centre of a newly-built processing plant for the manufacture of such components in the district of Charleroi, Belgium. Around 20t/hr of stainless steel slag will be processed in this specially designed mill.
UK Competition Commission talks tough
09 October 2013Well, it seems like they were serious.
The UK Competition Commission has provisionally decided that Lafarge Tarmac should sell off one of its cement plants in the Midlands. The Commission also wants the sale to exclude buyers from any pre-existing UK cement producer. The door is open from Holcim or CRH downwards to enter the UK market. Although if the enforced Lafarge sale of Hope to Mittal Investments in 2012 is indicative, it may well be to an industry outsider.
If the move goes ahead it will open up the Midlands and north of England from four cement producers - Hope Cement, Lafarge Tarmac, Hanson and Cemex - to five. Lafarge Tarmac's cement production capacity lead of nearly 4Mt/yr will be knocked down to nearer 3Mt/yr, putting it level with Hanson Cement's production capacity.
Unsurprisingly Lafarge Tarmac is not best pleased, putting out the following in response to the commission's announcement. "The Commission's assumptions and reasoning have serious flaws and the biggest loser in this process will be the customer. There is strong evidence to demonstrate there is effective competition in the sector – with new players having recently entered the marketplace."
The Commission also wants to increase competition in the supply chain for ground granulated blast furnace slag (GGBS). According to the Commission findings Hanson dominates the UK GGBS market and Lafarge Tarmac controls the market for its precursor, granulated blast furnace slag (GBS). So production facilities may need to be sold by both Hanson and Lafarge Tarmac.
As an aside it's worth noting that the Belgian Competition Council recently imposed fines due to anti-competitive practices also related to GGBS. Also, elsewhere in the news this week Irish GGBS cement producer Ecocem is aligning itself with the EU carbon roadmap to 2050, partly at least because its product produces less CO2 per tonne of cement. Whoever or whatever controls the supply of GGBS in the UK has implications for how emissions are lowered in the cement sector.
Other suggested measures from the Commission such as restricting the publication of UK cement market data seem problematic. Although it may make it more difficult for UK cement producers to collude it will also make it harder for related businesses (including press and industry analysts like Global Cement) to understand what is happening at any given time.
Finally, we have to ask what the effects of the Commission's suggestions might be at the start of an uncertain recovery in the UK construction market might be. According to the Minerals Production Association cement production fell from 8.5Mt in 2011 to 8Mt in 2012, the first decrease since 2009. 2013 seems set for modest growth on 2012. The implications of Commission's plans - if they happen – could be huge.
Ecocem releases carbon roadmap
09 October 2013Ireland: Ecocem has accused the Irish cement industry of failing to align its CO2 emissions with the European Union carbon 2050 roadmap. The producer of GGBS (Ground Granulated Blastfurnace Slag) cement made the comments in a document detailing its response to the Irish government's Climate Action and Low-Carbon Development Bill 2013. The EU carbon roadmap suggests cutting emissions in Europe by 80% below 1990 levels by 2050.
In its document Ecocem also attacked the European Union's Emissions Trading Scheme (ETS), saying that it provided strong incentives against promoting decarbonisation of the cement sector. It added that a transition to a low-carbon cement and concrete industry could create up to 1200 new jobs within five years.
Ecocem says its product has a carbon footprint of 19kg of CO2 per tonne of cement, compared with about 750 kg of CO2 per tonne it says is produced by the traditional Irish cement sector.
UK Competition Commission planning to create new cement producer
08 October 2013UK: The UK Competition Commission (CC) has provisionally decided that Lafarge Tarmac should sell a cement plant to increase competition in the UK cement market. The CC is also proposing to limit the flow of information and data between cement producers and to increase competition in the supply chain for ground granulated blast furnace slag (GGBS).
"The best way to disturb the balance of a market where producers have focused on retaining their respective market shares rather than competing is to create the opportunity for a major new entrant," said CC Deputy Chairman and Chairman of the Inquiry Group Professor Martin Cave.
In detail the CC has provisionally decided that Lafarge Tarmac should be required to choose between divesting either its Cauldon or Tunstead cement plant. The purchaser of the divested cement plant should be able to acquire a limited number of ready mixed concrete plants from Lafarge Tarmac subject to the purchaser's total internal cementitious requirement being capped at 15% of the acquired cement production capacity. The buyer would have to be approved by the CC and not be one of UK's existing cement producers.
Data currently published by the Minerals Products Association (MPA) and the Department for Business, Innovation & Skills should be delayed by no less than three months from the time period to which it refers before it can be made public. UK cement producers will also be prohibited (with a small number of specific exceptions) from providing their sales and production data to any other private sector organisation.
UK cement suppliers will be prohibited from sending generic price announcement letters to their customers. Instead, they should send letters that are specific and relevant to the customers receiving them.
Subject to further consultation on the GGBS supply chain, Hanson should divest two of its GGBS production facilities and Lafarge Tarmac should divest two of its granulated furnace slag production facilities, again to a suitable purchaser approved by the CC but not to another UK cement producer.
Responses to the CC's suggested measures will now be gathered before it publishes its final report by 17 January 2014.
