Abstract:
A fluidization segregation tester for bulk particular solids having, in combination,a base supporting a vertically extending shaft, a plurality of discs rotatable about the axis of the shaft and including an uppermost disc and a second disc stacked vertically on the base, each disc having a vertically extending bore spaced from said axis, said discs being independently rotatable to align the respective bores therein to form a sample chamber, the second disc having an aperture for supporting a sample jar, an expansion receptacle connected to the top of the chamber and adapted for filling the chamber with a sample of the solids, and means for connecting the bottom of the chamber to a source of gas under pressure, whereby the sample is fluidized and segregated and expands into said receptacle, the uppermost disc being rotatable to align the bore of the uppermost disc with the aperture in the second disc, whereby the sample jar collects the portion of the fluidized sample within the bore of the uppermost disc.
