    Fertilizer Powder and Granule Handling: Segregation, Caking, and Dust Control

    Bulk-blended fertilizer fails in three recurring ways: segregation between straight materials of different size and density, hygroscopic caking in urea and ammonium nitrate under humidity cycling, and dust release during bagging. Each failure mode maps to a specific diagnostic test rather than a single generic powder check.

    Why Kst Is Not Enough: What the Explosion Index Tells You and What It Misses

    Kst quantifies explosion rate-of-pressure-rise under standardized lab conditions. It does not directly describe how an explosion behaves in your vessel, at your turbulence level, or with your ignition scenario. This insight explains what the number means, where the cubic law holds, and when a competent person must go further than the test certificate.
