Algorithm for treatment of sedimentation curves in particle size analysis for powders

  • 34 Accesses

Abstract

An algorithm is suggested for calculating the particle size distribution in powdered materials from the results of sedimentation analysis in gravitational and centrifugal fields. Comparison of the particle size analysis for a Stokes' suspension of a specific fractional composition shows that the suggested algorithm eliminates a bias of the differential characteristic of the distribution toward an increase in particle size.
