This case study investigates the factors behind the ignition of a combustible dust cloud during a manual powder processing operation. In this example a process operator was tasked with manually tipping approximately 18 kg (40 lbs) of powder from a plastic drum, constructed from polyethylene, into a metal process vessel. The plastic drum contained a combustible powder that had a minimum ignition energy of 12 milli-joules. A metal chime was positioned around the circumference of the top of the plastic drum to provide it with impact protection from daily usage in the plant.

Cologne, Germany – During mining and subsequent storage of bauxite, a sedimentary rock for the production of aluminium oxide, a lot of dust is thrown up, which is a major challenge especially for the moving machine parts of the conveyor units. For this reason, Aluminium Oxid Stade GmbH (AOS), one of the major German alumina producers, decided to use energy chains from motion plastics specialist igus. For several years now, they have reliably supplied conveyor units and stockpiling equipment with energy, data and media.
