To avoid problems during the storage and discharge of cohesive bulk materials, silos should always be designed for mass flow. In the case of mass flow silos, the whole bulk material is in motion during discharge. Problems, as they may arise from funnel flow, can be avoided in this way.
In the case of funnel flow, only parts of the bulk material are in motion. This may lead to
Three physical quantities must be measured for a silo calculation:
These values are not constants but functions and are measured at different consolidation pressures depending on the pressure level in your applications.
Take advantage of our longtime experience in bulk solids analysis. Measurements such yield locus, wall friction, bulk density, time consolidation as well as bulk material moisture are carried out using certified measuring instruments in in our lab. This will give you all parameters necessary for a silo calculation. Structured process procedures ensure a high quality standard and economic workflows.
Automated and customizable reports simplify to use the results. Automatic analysis of the measurements and further calculations, such flow function, stress conditions in the silo, limiting criterion for mass flow or funnel flow, bridging (critical outlet diameter), load on the discharge device are online available after the measurements. It is even possible to automatically calculate and compare different silo shapes and dimensions automatically.
