Beckum, Germany – Sichuan Yadong Cement has been relying on a 12.5 km overland conveyor from BEUMER Group in order to convey limestone from their quarry to their silo. When constructed in 2009 it was the longest belt conveying system in BEUMER history (The company installed a longer system in 2016). In a second project BEUMER installed two additional overland conveyors, with an overall length of 13.7 kilometres, transporting limestone to the cement plant. Unlike the first project, the task here was to build the conveyor across inhabited areas. Noise emission limitations set forth by the government also needed to be considered.
Barnetby, UK — A global provider of quicklime and chalk products has resolved a significant fugitive material problem by implementing state-of-the-art containment and dust suppression on one of its primary limestone conveyors. After finding that an estimated 10 to 20% of the material load was spilling along the belt path, Singleton Birch implemented a control strategy from Martin Engineering that included a rebuilt transfer point as the material takes an approx. 6 metre (20-foot) drop from one belt to another.
“Reliability of operation is clearly the number one target for us. With our new Nordberg® GP330™ cone crusher we have secured a trouble-free, continuous secondary crushing process that enables us to produce daily some 4,000 tons of high-quality aggregates.” This is how Production manager Kurt Schön of Basalt-Actien-Gesellschaft (BAG) Rammelsbach quarry describes the company’s new GP330 cone crusher from Metso – the first of its kind in Germany.
