Project Yanbu PL 5 / Saudi Arabia

ZEMDES GmbH received an order from Yanbu Cement Co. (Saudi Arabia) in 2016. Yanbu Cement Co. operates several kiln lines at their location in Yanbu. For the kiln line 5, with a guarantee capacity of 10.000 t/d, we received the order to reconstruct the top cyclones of the 2-string preheater. The separation efficiency of the existing cyclones was only 82%.


Due to the spatial circumstances it was not possible to use cyclones from the ZEMDES standard series. The challenge was to implement an optimal technical solution for the customer under using of existing lower cyclone parts. ZEMDES supplied 4 new upper cyclone parts with the corresponding dip tubes. The assembly was carried out from Partner Teknik. The converted plant went into operation at the end of 2016. The performance test was carried out successfully in April 2017. With an achieved clinker production of approx. 11.500 t/d and a separation efficiency of 94,6%.
