How long do the measurements take?

Results are usually available about two weeks after sample receipt – depending on laboratory capacity and the number of samples. Time consolidation tests can extend the standard lead time accordingly. The results are then available online in the customer portal.

How much sample material is needed?

About 1 to 2 litres per sample for a complete bulk solids analysis for silo calculation; 0.5 litres is enough for a flowability measurement alone. You receive the exact amount with the quote. Please do not send unnecessarily large quantities – the material is homogenised and reduced to the required amount.

What is the maximum particle size?

For a standard-compliant measurement the material should not exceed a particle size of 2 mm. For coarser particles we assess the feasibility together with you.

What is the difference between flowability and flow function?

The flowability ffc is measured at one consolidation stress and is suitable for comparing bulk solids. The flow function σc(σ1) describes the flow behaviour across a stress range and is the basis for silo design.

What is needed for wall friction?

A wall sample of your wall material made to our drawing, which you receive with the quote. The surface should correspond to that of the silo. We keep standard materials in the laboratory on request.

Which evaluation do I receive?

A test report with an assessment of the flow behaviour. After the measurements for silo design, the calculation tool in the customer portal is also available to you – with silo loads to EN 1991-4, mass flow, arching and ratholing. The results serve as a design aid and do not replace an engineering silo calculation.
