Particle size distribution measuring device and particle size distribution measuring method

摘要

It provides a particle size distribution measuring apparatus and a particle size distribution measuring method capable of measuring the particle size distribution of raw materials including granulation and adhesion powder attached to the granulation with high precision. The particle size distribution measuring device 1 includes a granulation measuring device 2 for acquiring information indicating a particle size distribution of granules, an adhesive powder measuring device 3 for acquiring information indicating a particle size distribution of the adhered powder, and a raw material 13 ) Is provided with a computing device 4 that calculates the particle size distribution. The calculation device 4 includes a granulation particle size distribution calculation unit 43 that calculates a granulation particle size distribution based on information indicating a granular particle size distribution acquired by the granulation measurement device 2, and an adhesive powder measurement device 3 Based on the information indicating the particle size distribution of the adhered powder obtained from, the adhesion powder particle size distribution calculation unit 44 that calculates the particle size distribution of the adhesion powder, and the granular particle size distribution and adhesion of the granules calculated by the granulation particle size distribution calculation unit 43 A raw material particle size distribution calculation unit 45 is provided for calculating a particle size distribution of the raw material 13 based on the particle size distribution of the adhered powder calculated by the powder particle size distribution calculation unit 44.
