ABSTRACT:
The particle size range of a paper pulp suspension is determined by flowing the suspension up a measuring tube having a filter at the bottom thereof. When a plug of suspended material has formed, the inlet of the measuring tube is closed off. A liquid is then fed to a member which forms a gap in the plug of material and passes up through a measured portion of the suspension. The time taken for the liquid to pass through the plug to a given height is indicative of the mean particle size of the suspension.
