In July 2010 Rulmeca Tianjin Co completed the delivery of rollers for the second phase of China Resources Cement’s (Huarun Group) important project in Fengkai, China, – the longest belt conveyors ever built in Asia. Rulmeca Tianjin received the order at the beginning of 2009 for more than 180,000 rollers for two belt conveyor lines of 40 km.
The conveyors provide the limestone handling to link the mine to the cement plant in Fengkai, China. The two lines of parallel, long-distance curved belt conveyors feed one of the biggest cement plants in the world with limestone at 30,000 t/d.
Each line comprises three curved overland conveyors (11, 12 and 17 km) powered by a total of 19 units of 750 kW, with a belt speed of 5 m/s. The curved conveyors were designed to cross over 25 mountains but also roads and rivers.
