📊 Tromp Selectivity Curve (Grade Efficiency T(x), Cut Size d50, Imperfection I <0.25)

Air Classifier Tromp Curve & Imperfection Calculator

Calculate grade efficiency Tromp selectivity curves ($T(x)$) and Eder imperfection factors ($I = rac{d_{75} - d_{25}}{2 d_{50}} < 0.25$) across industrial powder classifiers: identify bypass fish-hook phenomena, eliminate fines contamination in coarse tailings, and particle classification yields.
