Name and Location
Cement clinker projects, Saudi Arabia.

Client
Yamama Saudi Cement Company.

Project Description
The project involves the construction of two turnkey cement clinker production lines.

The two 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 main components include two mobile primary crushers for limestone, each with 1 800 t/h throughput; three crushers each with a 500 t/h throughput, for additives; two crushers for correctives, each with 100 t/h capacity; and 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 will comprise six-stage and two-string preheaters with calciner, rotary kilns with clinkering zone burners, and clinker coolers.

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

Four combigrinding units, consisting of high-pressure grinding rolls, ball mills and separators, as well as downstream cement 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.

Quality control and monitoring will be handled by process control and laboratory automation systems.

Value
SR4.2-billion.

Duration
Both lines are scheduled to start operation in 2018.
