Yamama Saudi Cement Company will start up two clinker production lines, at a new site to the south west of Riyadh, in 2018. With a combined capacity of 20 000 tpd, the two lines are being built by thyssenkrupp Industrial Solutions. In 2016, AUMUND Fördertechnik GmbH won the order to supply the clinker conveying equipment for both lines.
The supply package includes 29 chain bucket elevators and 18 belt bucket elevators, in heavy-duty and lighter designs. AUMUND belt bucket elevators will be used for raw meal, while filter dust will be conveyed using AUMIND chain bucket elevators designed for low capacity.
Two AUMUND double chain bucket elevators, with a 2300 tph capacity, have been ordered per line as recirculating bucket elevators in the cement mill. Double chain bucket elevators have been specially designed by AUMUND for capacities over 1300 tph by combining two standard central chain bucket elevators. Both bucket strands run over the same drive shaft which is held by pillow block bearings and driven by double drive units. The symmetrical distribution of weight means that the chain and drive shaft will have long lifetimes. There is no mechanical connection between the two bucket strands. The chain wheels and tension shafts have separate bearings so that any lengthening of a chain that might occur after a long running time can be adjusted independently of the other.
Supply also includes six AUMUND pan conveyors as well as various flat gates, silo discharge gates, telescopic chutes and cleaning conveyors.
“We won the order among other things because of AUMUND’s expertise in advising on concept and design”, says AUMUND MD, Robert Gruss happily, when speaking of the trust of the customer. “Our strategy is to put our focus on a close relationship with our customers, accompanying them from the initial planning stages right through until after commissioning, and it is gratifying to reap the rewards.”
