The interpretation of ring shear cell results

In testing some powders on a Portishead shear cell it was found that the sample sometimes becomes grossly inhomogeneous, some portions being much more compacted than others.

Description
Summary:In testing some powders on a Portishead shear cell it was found that the sample sometimes becomes grossly inhomogeneous, some portions being much more compacted than others. A suggestion is made that this phenomenon may occur in other cell types without being detected, which would render interpretation of results more difficult, especially as similar inhomogeneities may occur in bulk handling plant. The Jenike shear cell was found to give values of strength of powders considerably greater than those of the Portishead cell.
