Instrument for Determining the Particle Size Distribution of Grain by Sedimentometric Analysis

摘要

The principle of sedimentation analysis for determining the particle size distribution of grain is described. The design and electrical scheme of a sedimentometric instrument, in which the grains are distributed depending on the velocity in the fluid are presented and their electrical conductivity during sedimentation is measured. The advantages of using the method of measuring conductivity compared to the traditional gravimetric (weight) method are given.
