Thyssenkrupp wins contract from Yamama Saudi Cement
26 November 2015

Thyssenkrupp has won a contract from Yamama Saudi Cement Company, one of Saudi Arabia’s biggest cement producers, to build two turnkey cement clinker production lines.

The two lines, with an overall capacity of 20,000tpd cement will be built at a new site around 80km east of the capital Riyadh. The value of the contract, in the higher three-digit million euro range, is the largest cement contract ever secured by thyssenkrupp.

The main components include two mobile primary crushers for limestone (each 1800tph throughput), three crushers for additives (each 500tph), two crushers for correctives (each 100tph) as well as two circular blending beds for limestone, each with a capacity of 80,000t and various additive storage facilities. Four QUADROPOL QMR2 roller mills with a throughput of 425tph and two 35,000t capacity homogenising silos will be used to grind and store the raw material.

The kiln lines comprise six-stage and two-string preheaters with PREPOL AS-MSC calciner, rotary kilns with POLFLAME-VN clinkering zone burners, and POLYTRACK clinker coolers.

Clinker will be stored in three 10,000t capacity clinker silos and two 100,000t capacity clinker storage facilities. Four combi grinding units consisting of POLYCOM high-pressure grinding rolls, ball mills and SEPOL separators as well as downstream cement coolers will each produce 300tph of cement.

The cement will be stored in six cement silos each with a capacity of up to 25,000t. The line will also feature six cement packing and loading stations. Quality control and monitoring will be handled by a POLCID process control system and POLAB laboratory automation system.

Yamama Saudi Cement and thyssenkrupp have been working together since the 1960s when the company placed an order for an initial 300tpd rotary kiln. Six more, ever bigger cement production lines were added in the years that followed.

Jens Michael Wegmann, CEO of the Industrial Solutions business area of thyssenkrupp: “Our partnership with Yamama is built on a longstanding tradition and dates back many decades. We are delighted that Yamama is once again putting its faith in our comprehensive experience in the turnkey construction of complete cement plants worldwide.”
