of Powders and Bulk Solids for Silo Design,
Flowability Tests, Comparative Tests.
The testing services we offer contain the measurement of flow properties using shear testers (e.g. computer-controlled ring shear testers RST-XS and RST-01.pc, Jenike-type shear tester) and other equipment (e.g. uniaxial compression test, lambdameter) for the characterization of bulk solids (e.g. for quality control or for silo design). Typical flow properties are:
compressive strength (in dependence on consolidation stress, time at rest,
temperature, humidity, concentration of flow agents etc.) .
Wall friction (friction
between bulk solid and wall materials like mild or stainless steel, concrete,
alumina, linings, etc.).
Bulk density (in
dependence on consolidation stress).
Stress ratio at uniaxial compression, wall friction coefficient and bulk density for silo design for strength (e.g. according to DIN 1055 Part 6, the new DIN EN 1991-4 or other codes).
