Turkey: Germany’s KHD Humboldt Wedag plans to increase its field staff at its office in Istanbul. They will primarily work on site in supervision for assembly and commissioning. The engineering company added that it intends to continue to increase its workforce in the country and that ‘experienced and well-trained cement experts’ should apply proactively.

Argentina: Germany’s KHD has been awarded a contract by Holcim Argentina for the upgrade project of a clinker production line at its Malagueño cement plant near Córdoba. Holcim Argentina intends to recommission its mothballed 1650t/day production line, which originally was supplied by KHD Humboldt Wedag in the early 1980s. Commissioning for the updated line is planned for mid-2019.

KHD’s scope includes the engineering and supply of mechanical equipment for raw material preparation and clinker production as well as electrical equipment in order to modernise and recommission the currently mothballed production line no 1.

Core equipment for the project includes: tertiary raw material crusher with a capacity of 250t/hr; ball mill drive for existing ball mill and new feeding equipment for raw meal preparation; separator for raw material grinding plant; kiln feed dosing system; four-stage preheater; rotary kiln 4.4m x 64m and drive system; revamping of existing clinker cooler with ‘fourth generation’ walking floor grate; main bag house for kiln/mill and clinker cooler; and main process fans.

Austria: Rohrdorfer Group has awarded an engineering, procurement and construction (EPC) contract to Humboldt Wedag, a subsidiary of KHD, for the modernisation of the kiln line at its cement plant operations in Gmunden. The upgrade will enable the flexible usage of a wide range of waste fractionally pre-treated derived fuels on a high substitution rate.

The modernisation project comprises the design and supply of KHD’s world´s first ever Pyrorotor Calciner Technology, as well as the replacement of the existing satellite cooler with a new generation Pyrofloor PFC2 clinker cooler. The existing three station rotary kiln will be fitted with a new kiln drive and a new kiln hood as well as kiln inlet and outlet.

With the installation of the new Pyrorotor Calciner Technology from KHD the Gmunden plant will be able to burn very coarse waste derived fuels including whole rubber tires, which will lead to drastically reduced requirements in regard to waste pre-treatment. Therefore, the kiln modification will also emphasise on pollutant emission reduction.

The contract includes: three new preheater cyclones; a new preheater ID-fan; a tertiary air duct; a Pyrotop compact calciner mixing chamber; Pyrorotor Calciner burning chamber technology, a Pyroclon Calciner Burning System; a new kiln bypass unit; a multi-fuel Pyro-Jet kiln burner for primary and secondary fuels; a new kiln drive and kiln hood; a Pyrofloor PFC2 clinker cooler equipped with a Pyrocrusher roller type clinker crusher; and Simulex plant simulation software.

KHD services include the dismantling of existing equipment parts as well as the engineering, design, supply and erection of new equipment including commissioning services. Commissioning of the new system is scheduled for April 2019.

Nepal: The German vertical roller mill (VRM) producer Loeshe GmbH has gained a new customer in Nepal. The cement division of Chaudhary Group, based in Kathmandu, has placed an order for a 25t/hr vertical roller mill for coal grinding for the 3900t/day (1.3Mt/yr) integrated cement plant that it is building in the Palpa region.

Loesche received the order though KHD, the lead bidder at the plant. The LM 26.3 D mill will be in operation during 2018 with a throughput of 50t/hr, 15% R on 90μm.

Turkey: Soma Cimento has ordered a 4000t/day clinker production line from KHD for its plant at Soma near Manisa. The contract includes engineering, equipment supply, and supervision of erection and commissioning, including KHD’s Simulex plant simulation system, which will simulate the operation of the plant. Commissioning of the plant is scheduled for the spring of 2018.

The core components of KHD’s new line are: a five-stage KHD Preheater with Pyroclon-R LowNO_x AF calciner, equipped with Pyrotop compact mixing chamber, tertiary air duct and Pyrobox calciner firing system; a Pyrorapid two-tire rotary kiln, with a diameter of 4.6m; a Pyro-jet kiln burner; and a Pyrofloor clinker cooler equipped with a Pyrocrusher System.

This project will be the third commissioning of KHD’s Low-NOx calciner with Pyroloop Technology in Turkey. It will be KHD’s 51st kiln line in Turkey. No value for the order has bee disclosed.

Africa: Humboldt Wedag, a subsidiary of KHD Humboldt Wedag International (KHD), has signed contracts worth over Euro80mfor the supply of equipment and execution of civil and erection works as well as supervision services for a cement plant in the western Sub-Sahara region of Africa. The contracts will be booked as order intake as soon as the pre-conditions for commencing project execution are fulfilled. No further information regarding the client or the country has been disclosed.

Angola: Cimenfort has inaugurated the start of its clinker kiln project. Industry minister Bernarda Martins presided at the event that marks the second phase of its ongoing upgrade scheme at its cement grinding plant in Benguela, according to the Angola News Agency. The first phase of its upgrades saw its production capacity rise to 0.7Mt/yr through an upgraded grinding system. Equipment for the project is being supplied by Germany’s KHD Humboldt Wedag.

Turkey: KHD has been awarded the contract to upgrade Nuh Çimento’s existing ball mill grinding unit in Hereke-Kocaeli located in Marmara. With this upgrade, the plant will increase the grinding capacity from 212t/hr to 408t/hr at 4000cm³/g according to Blaine. This will be the largest upgrade project to date for KHD. Commissioning is scheduled for the start of 2018.

NUH Cimento’s plant contains one of the largest ball mills in the world with a diameter of 5.8m, a length of 17.84m and a 10.4MW drive unit. The mill has been used for around nine years at the site. For the upgrade, KHD will install two new identical Comflex grinding systems next to each other, which can be operated independently, in addition to the existing ball mill system. The new compact system will allow for a significant reduction in the installation height of the Complex system.

The contract includes: two Comflex SC16-3250 clinker grinding units; two roller press RPM 16-170/180 with Rolcox system for control and monitoring; two VS 620 type cascade separators as static classifiers; two Sepmaster SKS-VC 3250 type efficiency separators as dynamic classifiers; two HKSK 190/265 system fans; and a two years spare parts package including one spare roller.

Germany: Eliza Suk Ching Yuen has decided to step down from the position of Supervisory Board Member of KHD Humboldt Wedag International (KHD). The resignation will take effect from the end of the next Annual General Meeting on 23 May 2017. Yuen was elected to the board in 2012.

Guinea: Guinee Industries Ciments (GIC) has awarded KHD Humboldt Wedag a contract to upgrade its cement grinding plant located in Conakry. GIC will integrate a Comflex system into GIC’s existing ball mills. The system will be the third Comflex system with roller press technology that has been installed in West Africa. The new system is expected to double the production capacity of the grinding line.

KHD’s scope includes the engineering and delivery of mechanical and electrical equipment, as well as the supervision of erection and commissioning for the new Comflex SC16-3500. The core equipment includes a RPS 16-170/180 roller press with Rolcox system for control and monitoring, a VS 620 cascade separator as a static classifier, a SKS-VC 3500 Sepmaster separator as a dynamic classifier and a HKSK 212-275 system fan. Commissioning of the Comflex system is scheduled for the end of 2017.
