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.
