Bhutan: A broken gearbox at a coal mill at the Penden Cement Authority plant in Gomtu has reduced its production. The plant has had intermittent mechanical issues with the gearbox in one of its two coal grinding mills since April 2017 leading to a breakdown in May 2017, according to the Kuensel newspaper. Then in June 2017 a similar problem occurred with the main drive gear in its other coal mill. The plant has been producing cement using imported clinker since then although it shut down completely for several days in late June 2017.

So far the cement producer has been unable to procure replacement parts. It has also been reported that the company has had difficulty importing clinker from India following the introduction of the Goods and Services Tax (GST).

Philippines: Eagle Cement has ordered a coal mill from Loesche for its Barangay cement plant in San Ildefonso. The vertical roller mill is intended for the third line at the plant and it is designed for grinding 54t/hr of mixed coal or 34t/hr of pet coke. The grist is ground to a fineness of 12% (coal) or 3% (pet coke) sieving residue with 90µm. The scope of supply also includes an LSKS-classifier and corresponding filters, blowers, an inertisation unit, the gas analysis and the main drives. All components are scheduled to be delivered before the end of 2017.

Algeria: The Saoura Cement Company has ordered a MVR 5000 R-4 mill from Gebr. Pfeiffer for a new cement plant at Bechar. The 350t/hr raw cement mill will grind material to a fineness of 12% R90µm and the drive will have a power of 3800kW. Delivery for the mill is scheduled for the first half of 2018. The MVR mill is the fourth that Gebr. Pfeiffer has received an order for in Algeria.

Germany: Cemtec has successfully transported a 170t cement grinding mill from its headquarters in Enns, Austria to a client in Bavaria. The transported equipment had an internal diameter of 4.6m, an outside diameter of 5.2m and a length of over 17m. Due to the size of the mill the transportation could not be carried out on motorways and the engineering company was forced to use smaller roads and inland waterways include the River Danube. Extra challenges included using additional haulage vehicles to cope with inclines of up to almost 14%, temporarily removing electricity and telephone cables in certain locations, laying road slabs at crossroads and shutting a motorway while the mill crossed it. The total transportation time took eight days.

Algeria: The Saoura Cement Company has chosen a MVR 5000 R-4 mill from Gebr. Pfeiffer for the new production line at its plant in Zahana. The 425t/hr raw cement mill will grind material to a fineness of 12 % R90µm and the drive will have a power of 3500kW. The expected moisture level of the input material will be 13%. The order was placed by CBMI, a subsidiary of China’s Sinoma, that is building a plant upgrade for Groupe des Ciments d’Algérie (GICA).

UK: It is hoped that a Euro23m upgrade project at Hanson’s Padeswood cement plant will be completed in early 2019. A planning application will be submitted to the local government in the summer of 2017 following consultation with local residents. The plant intends to install a new vertical roller mill to grind cement and to build a new rail loading facilities at the site.

“The plan is to mothball three of the old mills and install a new vertical roller mill capable of grinding up to 0.65Mt/yr of clinker. The new mill will be fully enclosed in a building, minimising noise and reducing the potential for escape of cement dust,” said plant manager Steve Hall. The project also includes construction of new cement silos alongside the existing railway line to load trains for delivery. At present the rail link is used to bring in coal to fire the kilns. In future, three trains a week will be despatched to Hanson’s depots in London, Bristol and Scotland or around 15% of total cement production.

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.

Egypt: Arabian Cement has announced three upgrade projects with a budget of US$7m. The projects include the construction of a mechanical crane to feed the kiln of the first production line, a new system to feed the cement mills and a new coal mill, according to the Daily Egypt newspaper. The coal mill project was announced previously in mid-2016.

Ivory Coast: LafargeHolcim intends to double its cement production capacity to 2Mt/yr from May 2017. The increase in production will follow the commissioning of a new 1Mt/yr mill, according to the Fraternité Matin newspaper. The mill has cost US$24.5m to install. LafargeHolcim operates a 1Mt/yr cement grinding plant in Abidjan. The upgrade is expected to raise local production to 5.1Mt/yr.

Qatar: France’s Fives has released further information about its work on the 5000t/day cement production line for Qatar National Cement Company. Fives installed the 6.6MW FCB B-mill of the raw meal grinding plant in March 2017. Installation of the raw mill shell was completed on 29 March 2017. The shell weighs 198t, has a length of 17.2m and a diameter of 6.4m. It was moved and erected using a self-propelled modular transporter. This project step followed the commissioning of the two FCB B-mills at the cement grinding plant in January and February 2017, and the signature of the related provisional acceptance in April 2017.
