Risks of fire and explosion

The risks of fire that the reprocessing of aluminium hold represent a big challenge. The mechanical recycling processes like shredding, conveying or filtering are at special risk.

Spark extinguishment for the aluminium reprocessing

At the Dormagen recycling specialist, all areas at risk are monitored by spark detectors. Besides the highly sensitive FM 1/8 spark detectors, detectors of the type DLD 1/8, that are insensitive to light, are used in areas with light ingress. Dirt accumulation on the optics of the spark detectors is prevented by means of air purge adapters. If sparks are detected, the automatic extinguishing system will be activated. A fine water mist spray extinguishes danger potentials within milliseconds. The low amount of water reduces the influence on downstream production processes to a minimum. The investment in additional safety was judged very positively by the approval authorities and the property insurer.
