Name and Location
Cement clinker production lines project, Saudi Arabia.

Client
Yamama Saudi Cement Company.

Project Description
The project involves the construction of two turnkey cement clinker production lines. The lines, with an overall capacity of 20 000 t/d of cement, will be built at a new site about 80 km east of Riyadh.

The project’s main components include two mobile primary crushers for limestone, each 1 800 t/h in throughput, three 500 t/h crushers for additives and two 100 t/h crushers for correctives, as well as two circular blending beds for limestone, each with a capacity of 80 000 t, and various additive storage facilities. Four roller mills, with a throughput of 425 t/h, and two 35 000-t-capacity homogenising silos will be used to grind and store the raw material. The kiln lines comprise six-stage and two-string preheaters with a calciner, rotary kilns with clinkering zone burners and clinker coolers.

The clinker will be stored in three 10 000-t-capacity silos and two 100 000-t-capacity storage facilities.

Four combi grinding units, consisting of high-pressure grinding and ball mills, separators and downstream coolers, will each produce 300 t/h of cement.

The cement will be stored in six cement silos, each with a capacity of up to 25 000 t. The line will also feature six cement-packing and loading stations. A process control system and laboratory automation system will handle quality control and monitoring.
