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.

UK: Hanson is considering spending around Euro23m on building a new clinker mill and other improvements at its Padeswood Cement plant. At present the site use four mills that are only able to grind about 40% of the kiln’s output, according to the Daily Post. A second phase of the upgrade project, dependent on production levels being increased, is planned to rebuild a railway link to the plant.
