The Automated Shear Cell modules for the FT4 Powder Rheometer allow assessment of powders in terms of shear strength. Using a shear cell on the high-specification FT4 platform enables the automatic generation of accurate and reproducible shear information. This is in addition to bulk powder properties data and the comprehensive powder flowability data provided by a standard FT4 measurement.

A range of shear cell options is available to suit different sample sizes and applications:

  • 85ml powder volume using 48 mm diameter shear head
  • 10ml powder volume using 24 mm diameter shear head
  • 1ml powder volume using 24 mm diameter shear head

Fully automated testing
Each shear cell is delivered with a library of testing programs in which the following stages are fully automated:

  • The standard conditioning cycle that prepares the sample for testing
  • A 'pre-shear' stage during which the powder bed is sheared to maximize the major principal stress
  • A single series of tests at a particular pre-consolidation stress, which may be sufficient for powder characterization. For example, a powder may be pre-consolidated to 10 kPa and then sheared at 9, 6 and 3 kPa, with pre-consolidation to 10 kPa between each test
  • More comprehensive, multi-stage testing to produce a range of yield loci corresponding to different pre-consolidation stress levels. Usually a given sample will be suitable for repeated shear testing to obtain the required set of yield loci. In this case the entire evaluation is automated.
