Combining performance with productivity
“The use of the Hitachi range of mining equipment at the Nuh Çimento jobsite located in Turkey has earned the brand positive feedback from this extremely satisfied customer, Hitachi Construction Machinery, Istanbul Branch Office.”
Located 80 miles (129km) east of Istanbul at Hereke, Nuh Çimento Sanayi A.Ş. is a Turkish company founded in 1966 that is engaged in the production and supply of cement, clinker and allied products. It established its first furnace clinker, production line clinker and grinding plants in 1969. Half a century later, Nuh Çimento’s integrated cement plant has increased production capacity to around 5.5 to 6 million tonnes per year and with a workforce of 500 plus employees, it has come to be regarded as one of the top industrial enterprises engaged in cement industry in Turkey thanks to its production capacity, product quality, improved management and organization structure, and rooted company culture. To meet customers’requirements in the market in a timely manner, the company has made large investments in its facilities, systems and processes, continually updating and expanding the plant in the years since. Most recently, in 2012, it commissioned a refuse-derived fuel (RDF) feeding system that is fed with mixed refuse from the surrounding neighbourhood to fire the cement ovens in the factory. The waste is first processed and then burned in the cement ovens, which is an alternative to using coal. In addition to alternative fuels, the company has also invested in an 18-MW waste heat recovery (WHR) plant, which helps in increasing efficiency and saving fuel costs over a relatively short period of time. At its onsite quarry in Hereke, Kocaeli, Turkey, Nuh Çimento mines marl and limestone together. Other materials such as coal, clinker, iron ore, truss, bauxite and gypsum are also handled here. The jobsite is an open pit mine located just next to the cement factory. The main goal is to dig the raw material and carry to the crusher which feeds the cement factory. The raw material mainly consists of marl and limestone.
According to Ahmet Gitmez, the manager responsible for the mine operation and mobile equipment at Nuh Çimento Sanayi AŞ, “The new Hitachi EH1700-3 Dump Trucks carry more material and consume less fuel when compared to the existing Euclid fleet. We are also very happy with the new features introduced by this product, especially the EDSC (Electronic Downhill Speed Control) System which controls the speed of the truck while going downhill.” The Nuh Çimento jobsite is positioned in such a way that the trucks have to go downhill loaded with an average of 18-20% grade ramps, he explains, as compared to general mine applications where the trucks go uphill loaded. “Hence, downhill speed control is a crucial factor for dump trucks at the Nuh Çimento jobsite and the new EDSC feature of Hitachi EH1700-3 truck enables the operator to go downhill without touching the brake pedal which adds to the operator’s comfort,” said Ahmet Gitmez.
Operators driving the new fleet of Hitachi trucks are also quite happy with the product and have no complaints, he added. “I would also like to point out that Enka’s fast response for service and spare parts have further heightened our overall satisfaction with these new machines.” As the distributor of HCM products in Turkey since 1982, Enka Pazarlama AS has been providing timely and efficient after sales service and spare parts to Nuh Çimento since many years. The delivery of four new units of EH1700-3 units in August last year has further cemented the fruitful relationship with Nuh Çimento bringing about a qualitative improvement not only in Enka’s business strategy but also boosting the activities of its sales and parts departments.
