Raw material particle size distribution measuring device, particle size distribution measuring method and porosity measuring device

摘要

Providing raw material particle size distribution measuring device, particle size distribution measuring method, and porosity measuring device for measuring porosity using the measured particle size distribution, which can measure the particle size distribution of raw materials including coarse particles and fine particles with high accuracy To do. A raw material particle size distribution measuring device, a coarse particle measuring device for acquiring information indicating the particle size distribution of coarse particles, a fine particle measuring device for acquiring information indicating the particle size distribution of fine particles, and a particle size distribution of coarse particles The coarse particle size distribution is calculated using the information shown, the fine particle size distribution is calculated using the information showing the fine particle size distribution, and the coarse particle size distribution and the fine particle size distribution are used as raw materials. And an arithmetic unit that calculates the overall particle size distribution.
