The required limestone is mined from a nearby quarry and reduced there by two mobile thyssenkrupp crushers. The new Yamama cement plant has its own power plant, a residential complex for permanent staff and a modern operating infrastructure. All operating situations are controlled via the polcid® process control system, while the automated polab® quality control system ensures optimum process and product control.
We have a partnership with Yamama Cement going back almost sixty years. Both sides know that they can rely on each other, even in difficult situations.

Line 1 is already producing clinker and cement
Together with the utilities, line 1 is running in Normal Operation Condition Period (NOCP) mode, meaning that the line is fully operational but thyssenkrupp still needs to conduct various performance tests. The next step is for the line to pass these Performance Guarantee Tests (PGT) and finally be granted the Provisional Taking-Over Certificate (PTO) by the customer.
Line 2 close to completion
Line 2 is currently in the cold commissioning phase, with cement production already having started in December 2020. The thyssenkrupp commissioning team from Germany is currently preparing the kiln for the planned start of hot commissioning in mid-February. The NOCP, PGT and PTO will then also follow for line 2 during spring 2021.
Around 120 people from 16 countries are currently still working on site for thyssenkrupp Saudi Arabia Contracting to complete the remaining commissioning activities for the cement complex.
