Granumetric Lite

Granumetric Lite blends sieve and laser particle-size data into a mass recipe that follows a packing or statistical target curve.

Enter passing values for each feed, pick Funk–Dinger, Fuller, Andreasen, Bolomey, Gates–Gaudin–Schuhmann, Rosin–Rammler or a certificate envelope, and read the mass fractions that best match the curve. Sliders always move mass. The plot is dry solid volume unless you switch to a certificate or a mass-basis model.

WHAT THIS EDITION INCLUDES
• Up to three components and sixteen size classes.
• Free packing and classical statistical targets, plus a custom passing table.
• Mix, reference and feed curves; linear or logarithmic size axis.
• Quality numbers: max and RMSE passing error, specific surface, fineness modulus, d10 / d50 / d90.
• Six starter examples (sand + crushed stone, cement + limestone, filler + pigment, mix certificate, 316L powder, three sands).
• Density catalog. Local gallery. PDF report and JSON of your own project.

This Lite edition does not include extra fitting methods, the engineering calculator toolbox, more than three components, CSV export, or the full example library. There are no in-app purchases.

A thin banner from Yandex Advertising Network is shown at the bottom of the screen. The app may use the device advertising ID to serve ads. Mix files stay on the device. No account is required.

WHO IT IS FOR
Process and materials engineers who set mass fractions of particulate feeds so the blended passing curve matches a packing model, a mill product, a grading envelope or a certificate.

Granumetric Lite shares its math core with the iPhone, iPad and Mac apps. The full Android toolbox with in-app purchase is published on RuStore.
