Abstract

The first experimental measurement of particle‐size distribution (PSD) from undiluted, rapidly flowing potassium chloride (KCl) suspensions using continuous‐wave photon migration techniques is presented. PSDs were obtained from a laboratory simulation of production‐line slurries used in the chemical fertilizer industry. Spectral measurements of concentrated, rapidly flowing slurry containing 25–40% KCl particles were used to calculate the suspensions' reduced scattering coefficient and PSD using inverse algorithms. Our PSD results agree excellently with sieving measurements. Refractive index is important in the calculations of the PSD and the suspensions' reduced scattering coefficient.
