Segregation

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.

Co-processing engineers particle morphology, density, and surface structure into a single composite excipient particle. Flow function and compactibility testing show what that buys formulators on continuous direct compression lines, and where it does not.

Dense-phase and dilute-phase pneumatic conveying create different particle contact mechanics, and the resulting attrition and segregation risk depends on velocity, solids loading ratio, and the powder's own attrition sensitivity, not on a fixed assumption about which mode is gentler.
