Abstract

The present invention relates to a compacting process suitable particularly for the compacting of materials with a pyrophoric tendency and especially for the compacting of scrap metal generated in the nuclear industry: and compacting means (4), and a compacting device including said means (4), appropriate for the implementation of said process. In said process the blanketed materials are compacted with optimized complementary external blanketing. The inert gas used for said external blanketing is characteristically conveyed via the compacting means (4) and blown in through their lower end (15).
