The minimum ignition energy (MIE) is one of the most important parameters for the assessment of explosion risks and the design of protection concepts when handling combustible powders. With the introduction of the ATEX regulation in Europe, the issue of ignition source analysis has become relevant not only in large bulk production plants where mostly powders of pure solids are handled, but also in mixing and standardization plants, in particular in pharmaceutical production, where mostly mixtures of different solids are processed. Investigations have shown the effect of mixing dust explosive powders with inert or less sensitive auxiliary materials [Bartknecht, Janes et al]. These investigations have been extended in this paper. A phenomenological mathematical description of the MIE of mixtures depending on the MIE of its components and the composition is proposed. The approach is the extended to the MIE of pure powders with complex granulometry.
