Bulk Solids Measurements

Comparison of sample flowability

Measurement of the flowability factor by yield locus determination (duplicate measurement) at one consolidation stress.
For selecting problematic materials, quality control or product certification.

(Please specify the maximum consolidation stress below or describe the application site so we can determine the reference stress.)

Comparison of flowability at multiple consolidation stresses

Measurement of the flow function by determining several yield loci at different consolidation stresses over a specified stress range.

(Please specify the maximum consolidation stress below or describe the application site so we can determine the reference stress. Depending on the size of the stress range, at least three different consolidation stresses should be measured for a reliable flow function.)
