KHD wins large upgrade project in Turkey

KHD has been awarded the contract to upgrade NUH Cimento’s existing ball mill grinding unit in Hereke-Kocaeli located in the Marmara region of Turkey. With this upgrade, the plant will increase the grinding capacity from 212 t/h to 408 t/h @ 4000 Blaine. This will be the largest upgrade project to date for KHD.

NUH Cimento has entrusted KHD with the upgrade of their ball mill system. The system contains one of the largest ball mills in the world (Ø 5.8 m x 17.84 m – 10.4 MW motor drive) and has been in operation for approximately 9 years in Hereke/ Turkey. For the upgrade, KHD will install two new identical Comflex grinding systems next to each other which can be operated independently for finish cement grinding or with a ball mill in the semi-finish grinding mode. This project will allow NUH Cimento to strengthen their position as one of the most significant companies in the Marmara region of Turkey.

The contract for engineering and equipment supply includes the following KHD core equipment:

Two Comflex SC16-3250 clinker grinding units:

2 x roller press RPM 16-170/180 with Rolcox system for control and monitoring

2 x Type VS 620 cascade separators as static classifiers

2 x Sepmaster type SKS-VC 3250, high efficiency separators as dynamic classifiers

2 x HKSK 190/265 system fan

two year spare parts package including one spare roller

The concept includes two new Comflex compact systems, in combination with the existing ball mill system. This ­concept, along with the 25 positive references regarding KHD roller presses in Turkey, ultimately won the customer over. Additionally, the new compact system will allow for a significant reduction in the installation height of the Comflex system.

With the installation of the Comflex grinding system in its newest compact design, NUH Cimento will have two identical systems that are equipped with the most advanced grinding technology on the market.

The commissioning is planned for the beginning of 2018.
