Faster friction measurement

Published: 1-Mar-2006


A new module for the Freeman Technology FT4 Powder Rheometer allows fast, fully automated measurement of wall friction using standard or custom materials in contact with powders under test.

In all processing machinery, powder is required to flow within containing surfaces such as hoppers, chutes and pipes. The frictional resistance between a given surface and the powder moving over it can be important to the powder transfer process.

The FT4's wall friction module allows experimental measurement of frictional resistance with a total test time of around 10 minutes.

The module comes with a set of four grade 304-stainless steel discs with various surface finishes. Additional discs featuring specific materials and surface conditions can be produced easily.
