A 4000 TPD clinker production line: turnkey execution of all works from piling and excavation to silos, a 130 m reinforced concrete chimney and around 5,500 tons of steel.

At the Aşkale Cement 4000 TPD plant in Gümüşhane, as part of converting the existing grinding and packing facility into a clinker production line, SİBA executed all reinforced concrete and structural steel works — from piling and excavation onward — on a turnkey basis, including design. This case study addresses the conversion of the existing facility, the multi-structure EPC scope, and the combined use of slipform and conventional methods.
The project involves converting an existing grinding and packing facility into a clinker production line. Such conversion projects require the new structures to be positioned in harmony with the existing plant layout and operation, and an execution plan suited to the site conditions.
The scope includes raw meal and clinker silos, bottom clinker and storage silos, a 130-metre tapered reinforced concrete chimney, preheater, cooler and filter structures, rotary kiln supports, mill foundations, and crusher and preblending structures. Approximately 5,500 tons of structural steel was fabricated across the project.
A cement line is not a single structure but a whole in which dozens of interconnected reinforced concrete and steel structures work in harmony.
The high-volume industrial structures were built using slipform and conventional formwork together. Slipform was preferred for continuous shell structures such as silos and the chimney, while conventional formwork was used for the geometrically complex process structures.
The Aşkale Cement Gümüşhane project is a multi-structure clinker-line conversion that combines all works — from piling to commissioning — within a single EPC scope, taking its place among SİBA's turnkey references in the cement sector.
