Can a fixed conversion factor always replace sieve analysis?
No. Correlation depends on the material and measurement definitions. Establish the relationship over the intended product range before changing a quality-control method.
Image-based particle width is often a relevant starting point for sieve comparisons, but a single shift factor need not describe every shape or distribution. Use representative material and examine both narrow fractions and the intended working range before transferring acceptance criteria to another method.
Planning measurement method comparison
Define the measurement question before selecting a preferred technique. Sample state, geometry and distribution weighting can explain differences between valid methods. Use paired measurements on representative material, retain the conditions and evaluate any proposed correlation across the actual working range before transferring an acceptance criterion.

Questions before selecting a configuration
How can Glen Mills help with this application?
Share comparison definition, material range, transfer evidence when you contact Glen Mills for further information or a quote. This helps focus the discussion on the preparation and evaluation described here.
How should a measurement result be assessed?
Use the size definition, distribution basis and acceptance criteria required by your measurement method. Discuss particle measurement with Glen Mills when a representative trial is needed to evaluate the configuration.
