The longest belt conveyor in company history
In July 2013, Asia Cement contracted us again for an additional, efficient overland conveyor to replace the trucks transporting the limestone from the bulk loading system to the cement plant. A mass flow of 2,200 tons of limestone per hour was necessary to meet the plant’s requirements. For this project, the first conveyor was to be customised to these requirements. We were planning a second troughed belt conveyor with an overall length of 13.7 kilometres. This is the longest system in our history.
Projects of that size are often unpredictable, so flexibility was needed from the engineers. During the planning phase, the cement manufacturer acquired another plant in Lanfeng, approximately ten kilometres away. Now we had to design the system so that both plants could be supplied with limestone. The team had to divide the overland conveyor in two parts. After 5.4 kilometres, an additional conveyor can be added to be fed to Lanfeng in the future. In February 2015, the system supplier started with the installation of the conveyor frame.
Both overland conveyors have four horizontal curves with radii of 1,200, 1,500 and 1,800 metres. We provided the engineering and the individual parts such as pulleys, motors, drive and control technology and the entire automation. The installation was monitored by a BEUMER supervisor and the wiring of the system was supported by a BEUMER electrical engineer. We were also in charge of the commissioning in May 2016. The troughed belt conveyor is now supplying three kiln lines, a fourth line is planned.
