China: KHD has reported NO_x emissions consistently below 50mg/Nm³ at Tianrui’s 2.0Mt/yr Weihui integrated cement plant in Henan province, where its Pyroredox gasifying reactor has been installed between the kiln inlet chamber and preheater calciner. The NO_x reduction after several months of operation was 66%, while reagent usage fell by 78% compared to with the plant’s selective non-catalytic reducer without a Pyroredox fitted. No extra power or fuel was used and production was unaffected. The Pyroredox requires two to four weeks’ downtime for its installation and is now operational at multiple cement plants across China.

US: Humboldt Wedag, a subsidiary of Germany’s KHD, has signed a contract with Lehigh Cement to supply a cement plant for a cost of more than Euro100m. The contract includes engineering, supply of equipment and structural steel as well as advisory services related to erection and commissioning of the unit. Lehigh Cement, a subsidiary of HeidelbergCement, has separately announced that it is currently preparing for a US$600m upgrade to its integrated Mitchell plant in Indiana. Construction work on the project is scheduled to start in 2020.

North America: Humboldt Wedag, a subsidiary of Germany’s KHD, has concluded a non-binding letter of intent with an unnamed customer in North America. The letter of intent for the engineering, supply of equipment and structural steel as well as advisory services related to erection and commissioning covers a potential order volume of more than Euro100m. The customer and Humboldt Wedag intend to enter into negotiations with the aim of concluding a corresponding engineering and procurement contract. Most of KHD’s orders come from the cement sector.

Germany: The executive board of Humboldt Wedag (HWG), a subsidiary of KHD Humboldt Wedag International (KHD), is preparing to cut approximately 80 jobs. It has made this decision in response to a ‘difficult’ business environment in cement plant construction industry in the near future. It said that in light of this, ‘personnel capacities cannot be sufficiently utilised.’ The measures required to implement the reorganisation will be discussed with the works council soon.

Germany: Gerold Keune has resigned as the chairman of the management board of KHD. He cited personal reasons. His resignation takes immediate effect. 

He will be succeeded by Yizhen ‘Mario’ Zhu. He will hold the post until the end of December 2019. In addition, Tao Xing has been appointed as an additional member of the management board. Zhu already served on KHD’s Management Board from 2011 to 2017. Xing served as member of KHD’s Supervisory Board in 2015 and as member of the Management Board in 2016.

Nepal: Germany’s Gebr. Pfeiffer has received an order via KHD to supply an MPS 225 BK vertical mill to grind coal for Samrat Cement. The cement company is building a new integrated production line at a plant in the Dang region.

The mill, with a drive power of 370kW, will grind 35t/hr of coal to a product fineness of 15% R 90µm. At the same time, the coal, which may have a feed moisture of up to 10%, is dried in the mill. An SLS 1800 BK integrated classifier will separate the ground coal into fine product and coarse product, with the latter being returned to the grinding zone to be again. The classifier will also allow petroleum coke to be separated to fineness degrees of <1% R 90µm.

The order was received via Gebr. Pfeiffer’s subsidiary in India. It will supply the main equipment for the mill and associated equipment for the grinding plant.

Germany: KHD has been awarded a contract to upgrade Thomas Zement’s grinding plant in Erwitte. The engineering, procurement and construction (EPC) contract includes process, mechanical, electrical and civil engineering services.
Mechanical and electrical equipment supply includes a roller press for raw material grinding, a static v-separator, an SKS dynamic separator and a KHD HKF process fan.

The deal also includes structural steel supply, erection and installation services for mechanical and electrical equipment as well as structural steel and supervision services for erection, installation and commissioning. KHD is also responsible for the tie-in of the new equipment to the existing raw material and product transport, as well as gas handling and treatment systems.

The erection and installation of the new grinding plant will be carried out during operation of the production line followed by a minimal possible switch over period. No value for the deal has been disclosed.

Russia: Filaret Galchev, the chairman of Eurocement, and Vladimir Sushkov, the chairman of the government of the Republic of Mordovia, has officially opened a Euro65m grinding unit at the Mordovcement plant. The new grinding unit includes two ball mills with a production capacity of 2.6Mt/yr, a 50,000t clinker warehouse and rail and truck despatch silos. Eurocement used equipment from Christian Pfeiffer, Claudius Peters, Aumund and KHD for the upgrade project at its subsidiary.

There have been quite a few new cement plant project announcements in the past week, with expansions announced in Mexico, Nigeria, Bangladesh, Indonesia, India and Uzbekistan. 11.8Mt/yr of new capacity has been announced in just a week, mostly from a whopping 9.0Mt/yr project in Central Sulawesi, Indonesia, the first in that Province. Notable in this project, as well as two of the others, is the involvement, once again, of large Chinese-based cement plant manufacturers and / or finance and associated influence from Chinese parties.

Of course, this trend is nothing new. The rise of Chinese cement plant manufacturers, particularly into Africa and other developing cement markets, has been covered in previous Global Cement Weekly columns. However, it does appear to be stepping up a notch in 2018 compared to previous years. So far this year we have reported on 21 confirmed Chinese cement plants being built in 15 countries other than China, from the planning stage to ‘up-and-running.’ A total of 37.2Mt/yr, more than the capacity of Germany, is being built across Algeria, Cambodia, Cameroon, Indonesia, Kyrgyzstan, Namibia, Nepal, Nigeria, Pakistan, Russia, Tajikistan, Turkey, Ukraine, Uzbekistan and Zambia. That’s not including a similarly large number of news stories where the supplier is not explicitly stated. This is seen a lot in Indian projects, as well as in Vietnam, where the cement sector appears to still be expanding, despite the government’s pronouncements. In many of these cases, and elsewhere, these unidentified suppliers are likely to be Chinese.

The driver for this increase in Chinese-led cement sector investment is, of course, the severe overcapacity in China’s domestic cement sector. The government is currently undertaking its most drastic capacity reduction measures so far. The ongoing integration of Sinoma and CNBM is one example of the lengths it will go to to reduce the current inefficiencies in the sector. This week the Chinese government reiterated its strict prohibition on new greenfield cement plants. It also warned that any producer that wants to upgrade its plant with a new line must only install the same capacity as the line that will be replaced, amid concerns that some were flouting this rule. This comes as the profits of major producers have been rising. Presumably the government would like them to climb further still.

So where does this leave the more established (read ‘European’) cement plant manufacturers such as Fives, FLSmidth, KHD and thyssenkrupp Industrial Solutions, some of which are fully or partly-owned by Chinese companies? Well, with fewer full-line projects available in developing regions due to the rise of the Chinese, they have become increasingly specialised in specific areas. Those that want European equipment will increasingly specify a pyro-line from Supplier A, a mill or two from Supplier B, conveyors and storage from supplier C, and so on. Arranging this, as it turns out, is something that Chinese plant manufacturers are quite keen to do. Take, for example, FLSmidth working for Sinoma (China) alongside Atlas Copco (Sweden) and Kawasaki Heavy Industries (Japan) on a cement plant in Indonesia. Indeed, FLSmidth signed a framework with CNBM on future collaborations in July 2018. FLSmidth and CNBM already have an extensive ‘back catalogue’ of joint projects. FLSmidth has valuable expertise that Chinese firms need to complete these kinds of projects.

Of course, another European supplier, Germany’s KHD, is mostly owned by China’s AVIC. In a forthcoming interview in the September 2018 issue of Global Cement Magazine, KHD’s CEO Gerold Keune states that the Engineering, Procurement and Construction (EPC) scene is now ‘completely dominated’ by Chinese suppliers. KHD fits in by providing a wide range of equipment but, crucially, great expertise in pyroprocessing and crushing solutions. It itself relies on smaller firms to provide their knowledge to specific parts of a larger project, be it conveyors, feeding systems or silos. Everyone is getting better and better, but in a smaller and smaller area.

Also in the September 2018 issue of Global Cement Magazine will be a report from the VDMA’s Large Industrial Plant Manufacturer’s group (AGAB) in Germany, which highlights another advantage for the Europeans: Digitisation. According to a VDMA survey, the industry anticipates a positive influence from digitisation activities on sales and earnings and expects to see margins improve by up to 10% as a result of the efficiencies it offers over the next three years. In this regard they are ahead of the Chinese mega-suppliers.

The conclusion from this wide-ranging column? The integration of Chinese weight and European know-how is stepping up a notch and will only accelerate from here. Can everyone be ‘winners?’ The next few years may reveal some of the answers.

Turkey: YD Madencilik, part of Üstyapi Insaat Group, has ordered a 5000t/day clinker production line from Germany’s KHD Humboldt Wedag. The plant will be built at Yiglica, Düzce in the Marmara region. KHD will be responsible for engineering and equipment supply, as well as the supervision of erection and commissioning. It will also provide its Simulex plant simulation software to mirror the operation of the new plant.

The new production line will consist of the following KHD core components: a six-stage preheater with Pyroclon LowNO_x AF calciner, equipped with a Pyrotop compact mixing chamber, tertiary air duct and the Pyrobox calciner firing system; a three tyre rotary kiln, with a diameter of 4.8m; a Pyro-Jet kiln burner; and a Pyrofloor clinker cooler equipped with a Pyrocrusher system.

After commissioning, KHD says that YD Madencilik’s plant will operate its most efficient six-stage preheater in Turkey. It added that close to 70% of Turkish cement production units have been designed and installed by KHD. Commissioning of the plant is scheduled for the third quarter of 2019.
