Granumetric

Granumetric optimises particle-size distributions for powder, aggregate and slurry mixes. You enter sieve or laser data for each component, choose a packing or statistical target, and read the mass recipe that best matches the curve — on iPhone, iPad and Mac, from one math core. The target is a dry solid-volume packing curve unless you switch to a certificate or a mass-basis model. Sliders always move mass fractions. Moisture is kept on the batch, not on the packing plot. WHAT YOU CAN DO • Blend two or more granulometries on a shared particle-size axis (test sieves ISO 3310 / GOST 6613 and laser-diffraction equivalents ISO 13320). • Fit to two Funk–Dinger packing models (classic 1994 and with grain-shape parameter α), Fuller, Andreasen, Bolomey, Gates–Gaudin–Schuhmann, Rosin–Rammler (Weibull), a custom passing table, or a certificate envelope. • See the mix curve, the reference, and…
