Turkey’s cement industry has continued to grow, despite the global economic crisis. The country’s clinker capacity has exceeded 64 million t, while its cement capacity is over 105 million t, with 48 integrated plants and 20 grinding stations as of 2010.
For decades, Somer International, an agent in Turkey, has been representing many European machinery and equipment manufacturers focusing on the cement market; namely Pillard Feuerungen GmbH, Fives Pillard, Vecoplan, Brokk AB, Bricking Solutions, Di Matteo, Standard Industrie and HGH. The company has started to cooperate with Bricking Solutions (a division of Brokk AB/Sweden), whose products include brick lining machine, safety cages/tunnels, ramps, etc., which are made of high quality aluminum (6061 T6). The modern designs meet international standards for engineering fabrication and safety standards, which means they have a relatively high initial price compared to steel products. Although it can be difficult to change the habits of Turkish cement manufacturers, especially when using higher priced alternatives, Bricking Solutions can provide training to help raise awareness of safety cages, safe and fast brick lining machines and Brokk remote control demolition machines. Ahmet Somer, the General Manager of Somer International, who has successfully completed three full days training, believes that safety issues will increasingly determine the type of product and process used in the country’s cement industry. It is believed that some recent fatal accidents will also speed up this change in the industry.
Another trend in the Turkish cement industry is the use of alternative fuels. This was first realised at the Akcansa/Buyukcekmece plant (a HeidelbergCement joint venture with Sabanci Group), where Vecoplan supplied the preparation (primary shredder, density separator, secondary shredder), conveying and storage of RDF (refused derived fuel). The plant is planning to increase the amount of alternative solid waste used.
Cementir/Cimentas has also made some RDF preparation investments in the Aegean region, while Vecoplan has installed a TULS (truck unloading station) for prepared RDF and a storage system to the Cimentas/Izmir plant.
Vecoplan also installed a complete system to Bursa Cement, including a 25 tph primary shredder, magnetic separator, density separator, 10 tph secondary shredder, storage and Vecobelt (the conveyor is specifically designed for RDF transportation), and automatic sampling station.
Besides the use of RDF in some plants, dried sludge has been successfully used as an alternative fuel in NUH Cement. Here, 70 - 80% wet sludge is dried down to less 10% and transported by a silobus to the system installed by Di Matteo. Dried sludge in the silobus is compressed to the silos and, after the weighing system, pneumatically conveyed through the pipes and burned by a Pillard burner in the calciner. The system has a capacity of 5 tph.
OYAK Aslan Cement (previously Lafarge Aslan Cement) has also recently completed its investment in RDF with a new generation NOVAFLAM burner from Pillard, while Ankara Bastas (Vicat Group) is another plant that has used RDF for several years.
